I’m a senior full-stack engineer and software architect with 20+ years of professional experience building production-ready web applications, APIs, and cloud-based systems. I work with modern JavaScript/TypeScript, React, Node.js, Kotlin, Java, Spring Boot, PostgreSQL, Elasticsearch, and cloud infrastructure (AWS/Heroku). My focus is clean architecture, reliability, and delivering solutions that actually solve business problems — not just code. I’m fast, precise, and able to take full ownership of a task, from planning to deployment. I’m currently available for freelance work in the Web2 and Web3/DeFi space, including: • Full-stack development (React + API + DB) • Backend engineering (Java/Kotlin/Spring, Node.js) • API integrations, microservices & automation • Database design & optimization • DevOps, CI/CD, cloud environments • Smart contract integrations or Web3 tooling • Technical troubleshooting, debugging, and performance fixes Let's build, improve, repair..
