Frontend / Fullstack developer

Building websites, apps, and AI features

I create websites, landing pages, dashboards, gateways, bots, and automation. Interface, logic, integrations, and launch — from brief to a working product.

My focusresult
  • Understand the brief and propose a working approach
  • Build around the key user scenarios
  • Ship something people can actually use

What you can order

Website and app development — one process to launch

I turn a brief, a mock, or a messy idea into a working digital product — from landing pages to fullstack services.

WEB

Websites and landing pages

A page built for a specific job: clear offer, responsive layout, forms, analytics.

APP

Web apps and services

Products with real user flows: accounts, roles, data, payments, integrations.

AI

AI inside the product

Chat, RAG, gateway, streaming — wired into the scenario, not bolted on as a widget.

API

Backend and APIs

Auth, databases, provider proxies, Docker, deploy — so the UI has something solid behind it.

MVP

MVP to test the idea

A first version you can show customers, collect feedback, and decide what to build next.

FIX

Work on existing code

I’ll read the legacy, fix the bottleneck, wire CI, and push it to release.

Contact

Shall we discuss a project or how we work together?

Write me directly or leave a short request in the form.

Always reachable

For projects, collaboration, and work offers.

Send a request

Describe the task, format, and the result you want. I’ll reply and suggest a next step.

You can write freely: project, MVP, rework, consulting, or collaboration.

Experience and stack

Fullstack with a shipping bias

I can join a team, own a feature end to end, or take a product from brief to production.
