I build AI-powered web and mobile apps from prompt design to App Store releases. 8 years of full-stack engineering, the last 2 focused on production AI products with real users.

Currently shipping:

- Vaffli, a couples app live on iOS and Android in 6 languages. Sole engineer: React Native + Node.js + OpenAI pipeline (2k+ requests/day, JSON schema, GPT-4), real-time pair-sync via WebSockets, RevenueCat billing, Redis job queue for scheduled push.

Stack: RN, Node, PostgreSQL, Redis, Firebase.

- CVSmith, an AI-powered ATS resume checker SaaS competing with Jobscan and ResumeWorded. Founder and solo engineer. Multi-model orchestration (OpenAI + Claude), 5-component scoring, AI bullet rewriter, Stripe billing. 22k+ scans last 30 days. Featured on Product Hunt.

Stack: Next.js, Postgres, OpenAI, Claude.

What I help with:

- AI integrations: OpenAI, Claude, prompt engineering, RAG, streaming, tool calling, JSON schema, multi-model orchestration

- Full-stack TypeScript: Next.js, React, Node.js, PostgreSQL, MongoDB, GraphQL

- Production React Native: iOS and Android, Expo, App Store and Play Store releases

- End-to-end delivery: Stripe, RevenueCat, real-time, push, infrastructure

Good fit if you are:

- A SaaS founder adding AI features and you want someone who ships, not prototypes

- A startup taking a feature from "let's build X" to production without hand-holding

- A team with a React/Node codebase that needs reinforcement for an AI roadmap

- A team in France, Germany, NL, UK, or anywhere in EU. I work fully remote with EU/UK time-zone overlap

8 years across US, UK and EU clients. Available 30+ hrs/week. English fluent, Russian native.
