We provide custom web development services, including web applications tailored to your workflows, data, and users, so your site converts better, integrates cleanly with the tools you already use, and scales without hitting a platform ceiling.
TRUSTED BY
We build the full range of web development services, from a marketing site to a multi-role platform. Some clients need one of these. Most need a few that work together. Here is what we cover.
Web apps with real business logic: user roles, dashboards, data models, and the workflows your team runs all day. This is custom web application and software development for products, where the software is what your business actually runs on.
Client portals, partner portals, and admin dashboards that turn scattered data into one screen people can act on. Role-based access, live data, and reporting your team checks instead of exporting to a spreadsheet.
Custom e-commerce for stores that have hit the ceiling of Shopify plugins. Inventory logic, payment flows, and checkout built around how you sell. We wired Stripe into the Champions platform and added live streaming on top of it, because merch sells better mid-broadcast.
Marketing sites and landing pages that load fast and read well on a phone. We handle custom web development design and build together, so the interface your designer approved is the one your users get, on every screen size.
The unglamorous software that saves the most hours. We replace manual handoffs, spreadsheets, and copy-paste work with internal tools that automate the process end to end, so your team stops doing by hand what code can do on a schedule.
Your web app rarely lives alone. We connect payment gateways, CRMs, ERPs, and internal tools through documented, versioned APIs. Good integration work is mostly invisible. You only notice it when it fails, which is exactly why we test the failure states first.
Marketing teams should not need a developer to change a headline. We build and customize content management systems your team can run without a ticket queue. WordPress where it fits, headless where it does not.
Slow sites lose rankings and revenue. We profile what is actually dragging load times, fix the render path, and get Core Web Vitals into the green, whether it is a site we built or one we inherited from another team.
Legacy code is not a moral failing. It is just code that outlived its assumptions. We rework aging platforms piece by piece: new front-end on old data, a monolith split into services, framework upgrades that do not require a full rewrite. Done without shutting the business down.
Manual and automated QA runs through every sprint, not as a phase bolted on at the end. Functionality, load, security, accessibility. If a release goes out with a known bug, it is because we discussed it with you and decided together it could wait.
Post-launch support and maintenance with real response times. Monitoring, security patches, performance tuning, and small feature work under one agreement. Your web app keeps earning after the launch party.
WHY CUSTOM
Most businesses that start with builders like WordPress, Shopify, or Wix eventually hit a ceiling. The design becomes limiting, performance slows, and every new requirement forces another compromise. Custom web development breaks that cycle. Instead of bending your business to fit a template, the software is built from the ground up around your goals, your users, and your growth plans.
The system fits how your team actually works, not the other way around. No feature you will never use, no missing one you need.
Custom builds carry only your logic, so they stay fast as traffic grows. When one startup moved from a template platform to a custom Next.js app, load time dropped from 4.2 seconds to 0.9, and organic traffic rose 64%.
Custom APIs connect directly to the systems your operations depend on. No middleware hacks, no limited connector apps.
Add features, user roles, and traffic on an architecture built to grow, instead of migrating to a new platform every two years.
Semantic markup and clean code help search visibility, security fits your actual threat model, and you own 100% of the code and IP.
A custom web development project typically includes discovery and planning stages, iterative design, agile development, and structured launch procedures. Here’s how it works:
Every custom web development project starts with a deep understanding of your business. We interview your team, map the workflows, and write down what the system must actually do. We do not stop at what pages you want. We identify the outcomes you need, whether that is organic traffic growth, higher conversion, workflow automation, or complex data handling. This is where scope creep goes to die. (Most budget overruns are born in skipped discovery.)
Custom UI/UX is built around your brand identity and your users’ behavior, not modified from a generic theme. Wireframes first, visuals second. You review clickable prototypes before a single line of production code exists, so changing your mind is cheap. Custom development means the design responds to your business needs, and that focus on tailored solutions shows in navigation that stays out of the user’s way.
Development follows agile, in two-week cycles with a demo at the end of each one. Our full-stack development approach covers front-end frameworks (React, Vue), back-end development (Node.js, Python), headless CMS development, API development, and scalable infrastructure. You see working software every fourteen days, not a status report.
Automated test suites run on every commit. Before launch, every project goes through performance optimization testing: Lighthouse audits, core web vitals verification, security assessments, accessibility checks (WCAG compliance), cross-browser, and load testing. Manual QA covers the paths robots miss, like a user rage-clicking the back button mid-checkout.
Staged rollout, monitoring dashboards live from hour one, and a rollback plan we hope to never use.
After deployment, we provide training and documentation so your team can manage content updates confidently. Custom content management systems let non-technical staff make content updates without coding and without compromising quality or site performance. The team that built your platform stays available for it. No handoff to strangers reading documentation for the first time.

ENGINEERING
Anyone can promise clean code. Here is what that means in our repositories, specifically.
Code merges trigger automated builds and tests, so integration problems surface in minutes instead of during launch week.
No developer merges their own work unreviewed, including the senior ones. Especially the senior ones.
Unit tests, integration tests, and end-to-end coverage on critical user paths.
Every change is traceable to an author, a ticket, and a reason. When you take ownership of the code, you take ownership of its story too.
Infrastructure as code, environment parity between staging and production, and deployments that do not require a maintenance window at 3 a.m.
Repository, documentation, infrastructure configs. If we ever part ways, you lose nothing but our company in your Slack.
Challenge
Willo, a UK recruiting startup, was up against phone screening. Recruiters in high-turnover industries were burning entire days on calls just to shortlist candidates, and they needed a secure way to screen applicants remotely without making candidates install anything.
Solution
We built the web platform around asynchronous video. A recruiter sets up a branded interview from a desktop, tablet, or phone in under three minutes. Candidates record answers from any device, no app, no download, and submit only when they are happy with the take.

Challenge
A US sports startup wanted fans buying merchandise directly from their favorite athletes, with purchases happening during the broadcast moment rather than after it. Nothing off the shelf combined commerce with live video.
Solution
Our team started with the e-commerce core: catalog, Stripe payments, order flow. Live streaming came next, so an athlete can sell mid-stream while fans watch. Mobile shipped on React Native, the web storefront on React and Next.js, both consuming the same Node.js and GraphQL back end on AWS.

Challenge
Younergy, a Swiss CleanTech company, makes solar power available by subscription. Its installers and clients needed to track energy consumption, import, export, and generation remotely, and no existing tool did that in a form a non-engineer could use.
Solution
Working alongside the client’s team, we designed and built the front end of a management web app around a single dashboard. Every metric an installer needs sits one click deep, and the same interface holds up for individual homeowners, EPCs, and PV distributors.

A custom web development service earns its price through domain knowledge. It is the difference between a developer who asks what HIPAA is and one who architects for it before kickoff.
Patient portals, telemedicine platforms, and clinic management tools built to HIPAA requirements from the first sprint.
Payment infrastructure, digital wallets, and investment platforms where a rounding error is a lawsuit. We build with audit trails and encryption standards that satisfy actual auditors.
Storefronts and marketplaces engineered for conversion, from product discovery through checkout and returns.
Learning management systems and course platforms with progress tracking that teachers actually use.
Listing platforms, virtual tour integrations, and CRMs for teams that close deals on their phones.
Booking systems, workout platforms, and membership tools. Explore our shipped products in the public portfolio.
Applicant tracking, async video interviewing, and screening tools that cut days off time-to-hire. We built Willo’s video interview platform end-to-end.
Booking engines, itinerary tools, and property dashboards that hold up when inventory and prices change by the minute.
Feeds, messaging, profiles, and moderation built to stay fast as the user base grows from hundreds to hundreds of thousands.
Each project gets the framework that fits its performance, timeline, and team needs.
React, Next.js, TypeScript, Vue.js, Angular, HTML5, CSS3
Node.js, Python, Ruby on Rails, NestJS, Spring
REST, GraphQL, JSON, webhooks
AWS, GCP, Docker, Kubernetes
Full-stack development teams are assembled per project. If your platform needs React developers or Python engineers specifically, we staff for it.
The cost of custom web development comes down to four things: how many features, how many integrations, how strict the compliance scope is, and how the team is structured. Below is a practical breakdown by tier so you can size the project before you ever talk to us.
$7,500–$25,000
1–3 months
Best for: companies that need a fast, credible web presence they fully own and can update without a developer.
$20,000–$60,000
2–4+ months
Best for: startups validating an idea or companies replacing a workflow that spreadsheets and off-the-shelf tools have outgrown.
$50,000–$125,000+
3–6+ months
Best for: scaling businesses building a platform that multiple user types depend on every day.
A few things move the number. Third-party integrations add cost per system connected. Compliance requirements (HIPAA, PCI DSS, SOC 2) add architecture and audit work. Custom web app development services with real-time features, like live streaming or collaborative editing, sit at the higher end.
You get a fixed scope, timeline, and budget in writing before development starts. Milestone billing, no surprise invoices.

VERIFIED REVIEWS
Clients rate our web development services 4.8 on Clutch based on 70+ reviews and 4.8 on GoodFirms based on 30+ reviews. Both profiles are public, unedited, and occasionally blunt.
Most projects fall between $7,500 for a marketing site and $125,000+ for a complex platform with multiple integrations. Scope, business logic, and compliance requirements drive the number. We provide a fixed quote after a discovery call, and our cost calculator gives a fast first estimate.
Most custom web projects take 6 to 16 weeks to complete. An essential custom site typically takes 6–10 weeks. Advanced web applications with complex integrations and custom features run 3–6 months. Enterprise solutions with compliance requirements and extensive integrations can take 6–12 months or longer.
Timeline factors include the complexity of features, number of third party integrations, design review cycles, content readiness, and stakeholder feedback speed. A clear discovery phase and disciplined project management keep timelines on track and prevent scope creep.
Builders like Wix or Squarespace are the right tool for simple sites with standard needs. Custom web development is for products: applications with unique workflows, heavy integrations, or performance requirements a template cannot hold. If your roadmap includes features no plugin offers, you have already outgrown the builder.
Yes. CRMs, payment systems, marketing platforms, internal databases, and anything else with an API. Integration work is scoped per system during discovery, so the quote you approve already includes it.
You do. LITSLINK transfers 100% IP ownership on every engagement, including repositories, documentation, and infrastructure configuration. No licensing tails, no dependency on us to keep your own product running.
We architect for the load you expect in year two, not the load you have at launch. Modular services, cloud infrastructure that scales horizontally, and database design that survives a traffic spike from a good press day.
Ongoing maintenance ensures websites stay secure and updated. Post-launch support is essential for maintaining custom websites – it includes security updates, performance monitoring, bug fixes, and feature enhancements.
We offer structured maintenance agreements that cover regular dependency updates, security patches, performance optimization, and technical support. Choosing a partner impacts the product, timeline, and business outcome, which is why our commitment extends well beyond launch day.
No. Every custom site we deliver includes a user-friendly admin interface or CMS that allows your team to manage content, update pages, and handle routine tasks without writing a single line of code. Custom content management systems allow easy content updates without coding.
We also provide training and comprehensive documentation so your team has the confidence and access to manage day-to-day operations independently. Well-designed custom dashboards make ongoing management straightforward, even for non-technical staff.
We offer a free, no-obligation project consultation where we’ll talk through your business goals, assess your current platform’s limitations, and outline what a custom solution would look like – including timeline and budget expectations.
