Custom Web App Development

Custom web app development — software that does not rot, built in Vue 3 and TypeScript

Off-the-shelf tools take you far, and then they stop. At some point you need a dashboard or a client portal that works the way your business works. This is what custom web app development is for. I design and build it end to end: frontend, backend and deployment.

I have worked on 40+ projects for clients including Adidas, OPAP and About You, spanning booking platforms, enterprise backoffice systems and internal tools. I specialize in Vue 3 on the frontend, with TypeScript, Node.js or Laravel across the rest of the application.

The cost of scattered tools rarely shows up on an invoice. It appears in the time spent copying data between systems, or in a process that depends on one person's memory. As the business grows, those workarounds become harder to manage.

A custom web app can earn back its cost when it replaces an expensive process. Repeatable copy-paste becomes automation, disconnected tools can share the same records, and reports use data already in the system. You own the code and control the roadmap.

If the application needs an assistant, search over your own content or generated output, I can add AI features with evals and cost controls through the same build process.

01
Technical Audit
I map your requirements, data and integrations first. You get a clear scope, an architecture proposal and a realistic estimate before any code is written.
02
Architecture & Design
Database schema, API contracts and component architecture are defined up front, so surprises surface on paper, where they are cheap to fix.
03
Development & Build
Short iterations with TypeScript and a tested API. Continuous integration, preview environments and milestone reviews make progress visible throughout the build.
04
Deployment & Warranty
Deployment, data migration and documentation, with a 30-day technical warranty after go-live. The code lives in your repository from day one.

What custom web app development delivers

  • A custom web app that fits your workflow, not the other way around
  • TypeScript, tests and documented boundaries that make maintenance and future extensions easier to assess
  • Performance and accessibility tested during the build and before release
  • Full ownership: code, documentation and deployment in your hands

What does custom web app development cost?

It depends on scope. Send the outline through the contact form and I will reply by email with an estimated cost and timeline. If the fit is right, the proposal uses fixed milestones instead of open-ended hourly billing.

The schedule depends on workflow complexity, integrations, data migration, access rules and test coverage. I map those dependencies first, then reply with an estimate and split the work into reviewable milestones.

Yes. I build the frontend and the Node.js or Laravel API, with PostgreSQL or MySQL underneath. One engineer owns the whole stack, so architecture decisions do not get lost between frontend and backend handoffs.

You do. Everything lives in your repository from day one. You get documentation and a 30-day technical warranty after go-live.
