Senior full-stack and mobile engineer with 15+ years of commercial experience building and supporting production systems.

 

I deliver complete solutions across backend, web frontend, mobile applications, databases, integrations, deployment, and production support. My primary stack is Node.js, TypeScript, React, Flutter, PostgreSQL, Redis, RabbitMQ, Docker, Linux, and CI/CD. I also work with Python, Go, Java, C/C++, REST/SOAP APIs, automation, AI integrations, and game development.

 

Recent work includes enterprise systems for a retail network of 800+ stores, a procurement and customs-document platform used by 5,000+ users, offline-first Flutter applications with reliable synchronization and DataMatrix workflows, and a legally significant document-signing platform integrated with CryptoPro.

 

I can help with focused, fast-turnaround work: bug fixes, API integrations, React or Flutter improvements, Node.js backend tasks, database issues, Docker setup, scripts, automation, and technical troubleshooting. I provide clean maintainable code, clear communication, reproducible setup instructions, and realistic scope estimates.
