What I'm looking for

I’m open to Senior or Lead Fullstack Developer and System Architect roles, where I can take full ownership of the technical product lifecycle.

At Freelance, I operate a private R&D lab focused on AI-native SaaS products. I’ve designed and shipped MVPs, including an AI feedback assistant that turns customer surveys into sentiment analytics and product reports, and a community bot that uses RAG to answer questions from an internal knowledge base.

At THE GAME, I developed an EdTech product from zero to 2,000+ DAU and shipped its MVP in 2.5 months. Earlier, at X5 Digital, I built a supplier portal and reusable design system that cut typical interface development time by 3x; at Бизнес Молодость, I helped build an EdTech ecosystem supporting 3,000+ concurrent users.
