What I do

One thing,
done properly.

Web & Mobile Development

Frontend engineering,
end to end.

For teams and founders who need an interface built once, built right, and still maintainable a year from now. Embedded in your team or freelance — the standard doesn't change.

Frontend architecture Component systems, design systems, and state architecture that stay coherent as the team and the product grow.
Web & mobile delivery End-to-end feature work across both platforms — React Native and Flutter apps running on iOS and Android, shipped to the stores.
API integration REST APIs, auth, and the unglamorous data-flow edges that decide whether a product actually ships.
Performance Core Web Vitals, bundle discipline, and animation that never drops a frame.

The path

Four years,
eleven products,
one standard.

2022 — The start

First paid site, built freelance for a shop that had none — catalogue, contact, and vanilla JavaScript, HTML and CSS. Hosted and indexed so customers could actually find it. One rule from day one I’ve never dropped: understand the whole system, not just my ticket.

2023 — Full stack

Built a wholesale ecommerce platform end to end — Next.js and MongoDB, stock that stayed true in real time, an order pipeline over Nodemailer, and online payments. Learned to own the whole system, not just the screen in front of it.

2024 — Scale

Frontend across six client products at an agency: an ERP, a leadership-evaluation SaaS, a social music platform, two ecommerce builds — and a mobile migration off Ionic-Angular onto React Native. Different domains, same standard.

2025 — Product

Joined Alfred. The partner-shop web app in React and Redux, the drivers app in React Native, the customer app in Flutter. Three codebases, three audiences, one product.

2026 — Promoted

Moved up to semi-senior — not for time served, but for ownership and technical decision-making. Now leading feature work across a two-platform fleet-management monorepo in Next.js, Tailwind, HeroUI and Zustand.

Today

Eleven products live across web and mobile. Looking for the team or the client whose next thing deserves to be built properly.
