An engineer who thinks in products, not just tickets.

I'm a full stack web developer with 8+ years of commercial experience, working with agencies, startups and established businesses. My core stack is the JavaScript ecosystem end to end - React, Next.js and TypeScript on the frontend, Node.js and NestJS on the backend - and I take projects from A to Z: from the first idea and planning to launch and support, for any digital business task.

Before IT, I earned a master's in business and service management and worked in analytics, digital marketing and project management - so I think in users and business results, not just code. AI tools are part of my daily workflow, and I stay responsible for every line that ships.

Web applications first. Everything around them when needed.

Main focus

Web application development

Product-grade frontends and the APIs behind them - typed, tested and built to be maintained by the next developer.

Agentic AI development

An agentic workflow with Claude Code: a clear spec first, AI agents take the routine, and I review, test and own every line that ships. Faster delivery without cutting corners.

From concept to launch. One person, no hand-offs.

Every project goes through the same six stages - whether it is a company website or a full web platform. You always know what happens next, and who is responsible for it: me.

  1. 01

    Concept

    Who the product is for, what problem it solves and what success looks like in numbers.

    GoalsAudienceSuccess metrics
  2. 02

    Planning & PM

    A one-page spec with scope, milestones and estimates. Clear priorities and regular updates - no surprises.

    UX / UI

    User flows, wireframes and a clean interface that fits the brand and works on every screen.
