Web application development

Eight years of shipping production web applications – from legacy AngularJS rescues to greenfield React platforms. I build systems that survive scale: strict typing, lazy loading, test coverage and an architecture the next engineer can actually read.

What you get

Production-ready application

A deployed, monitored web app – not a prototype. CI/CD pipeline, error tracking and performance budgets included.

Architecture that scales

Module boundaries, state management and data flows designed for the team you'll have in two years, not just today.

Test coverage that matters

Unit and E2E coverage (Jasmine/Karma, Cypress) on the flows that pay your bills – auth, checkout, data integrity.

Legacy migration

Incremental AngularJS → Angular or monolith → modular migrations without stopping feature delivery.

How it works

  1. 01

    Scope

    One call + a written brief: what we build, what we explicitly don't, and how we measure done.

  2. 02

    Architecture

    System design, data model and milestone plan you can hold me accountable to.

  3. 03

    Build

    Weekly demos on a staging URL from week one. No black-box sprints.

  4. 04

    Ship & handover

    Production deploy, docs, and a walkthrough for your team.
