What I build.

Freelance full-stack development, end to end — from a startup MVP to a production platform. Every service below is backed by work that is live today.

Fractional CTO for startups

A part-time CTO for startups that need technical leadership before they need a full-time one — architecture, roadmap and delivery, from someone who still writes the code.

MVP development for startups

I build the first version of your product end to end — the app, the backend, payments and the admin panel — scoped to what proves the idea, so you can put it in front of real users.

DETAILS

Mobile app development

I build iOS and Android apps in React Native and Expo, from the first screen to the store — with native Kotlin and CallKit modules where they matter, and the backend, payments and admin panel behind them.

Encrypted chat & video calling apps

I build messaging that only the people in the conversation can read — on the Signal Protocol — and group voice and video calling on WebRTC, for teams that can’t afford a leak.

SIGNAL PROTOCOL · WEBRTC · MEDIASOUP · SQLCIPHER · CALLKIT · NESTJS

DETAILS

AI integration & LLM features

I add AI where it does real work — chatbots that answer from your own data, LLM-driven features inside production apps, and pipelines that turn spreadsheets and documents into finished output — built with the same backend engineering as the rest of the product.

Web apps & admin dashboards

I build web apps people use every day — SaaS platforms, admin consoles, data dashboards and product sites — in Next.js and React, together with the backend and data behind them.

Backend & API development

I build complete backends in NestJS on PostgreSQL and Redis — auth, payments, background jobs and real-time — sized for the users you have and the ones you’re planning for.

DETAILS

E-commerce & Stripe payments

I build the parts of a business that take money: Magento stores with a real catalogue and checkout, and Stripe payments with subscriptions, wallets, escrow and payouts.
