About

Professional summary

I am a Full Stack Developer with hands-on experience building end-to-end web and game-related products using React.js, Node.js, Python, JavaScript, SQL, HTML, and CSS.

I have worked in a fast-paced startup environment, where I owned features from concept through production across both client-side and backend systems. I am comfortable delivering under tight deadlines while maintaining code quality, stability, and test coverage.

My experience includes developing automation pipelines for AI-powered content generation, building internal development tools and CLI utilities, and creating external websites that improve team workflows.

I bring a cross-functional mindset shaped by work as a developer, tester, project manager, and content creator. I have contributed to agile delivery cycles, game mission implementation, code reviews, bug fixing, and frequent pull request merges.

I value reliable engineering practices and regularly write unit and integration tests using Jest and Pytest. I enjoy collaborating with teams to turn product requirements into practical, production-ready solutions.
