Full-Stack Software Engineer building web and mobile products with React, React Native, Next.js, Node.js and Go.

I work across the full product lifecycle — from UI/UX and frontend architecture to backend APIs, PostgreSQL, testing, CI/CD and production delivery.

My focus is on shipping maintainable products, improving system performance, and making pragmatic architecture decisions that have measurable impact.

• End-to-end product delivery
• React, Next.js & React Native applications
• Backend services with Node.js, NestJS & Go
• REST APIs, PostgreSQL & application data flows
• Performance, caching & scalable architecture
• Automated testing & reliable delivery
• UI/UX, Figma & reusable design systems
• Docker, CI/CD & production infrastructure

• Delivered a real estate marketplace MVP in under 3 months
• Reduced infrastructure costs by 10x through rendering and architecture improvements
• Reduced CMS/API overhead by 30% by redesigning application data flows
• Improved page-load times by several seconds through rendering and caching optimization
• Built automated testing and CI/CD workflows for safer, more reliable releases

A full-stack reading application for language learners, built around React Native + Go + PostgreSQL.

The backend is being developed as a production-oriented modular monolith with:

• Go + chi
• PostgreSQL + pgx
• REST APIs
• JWT authentication & refresh tokens
• database migrations
• translation caching
• structured service / repository / handler layers
• Docker
• graceful shutdown & health checks

The mobile client is designed around reading, contextual translation, personal vocabulary, notes and reading progress.
