Hi, I'm Andrey Savelev, a senior front-end engineer with 10+ years of experience and hands-on back-end skills in Node.js, NestJS and FastAPI. I help companies develop, release, and maintain their products.

I follow AI-assisted development practices and adopt coding agents where company policy allows, with a focus on code privacy, human review, and verification.

What I focus on

• End-to-end delivery: taking features from API design and back-end logic to a polished UI and release
• AI-assisted development: building practical workflows with coding agents, backed by code review, tests, and verification
• Performance: making applications faster and more efficient on both the client and the server
• Architecture: structuring front-end and back-end code so that it stays scalable and maintainable
