About

Professional summary

I am a full-stack developer with more than 10 years of experience building web and mobile products, from customer-facing applications to admin systems and internal business tools.

My work spans front end, back end, and mobile development. I mainly use React, Vue, Next.js, and TypeScript on the front end, and Node.js, PHP, Python, and Java Spring Boot on the back end.

I have built products for SaaS, enterprise platforms, e-commerce, retail operations, CRM, dashboards, knowledge bases, and workflow automation. I am comfortable working across the full delivery cycle, including API design, authentication, database design, integrations, and production support.

In recent years, I have focused on AI-powered business tools such as AI agents, RAG knowledge assistants, prompt workflows, and internal AI training. I care about building features that are practical, understandable, and useful in real business settings.

I also have experience with Flutter and React Native for cross-platform mobile features, as well as data handling with MySQL, PostgreSQL, MongoDB, and Redis. I am used to working on systems that require reliability, permissions, and careful release management.

I value clear communication, code review, and responsible use of AI tools. I am comfortable moving between frontend and backend work, and I stay engaged when production issues need to be solved.
