Portfolio v1 / Legacy

Aleksei Lopatin

Full-Stack Developer

React · Next.js · TypeScript · Python · FastAPI · PostgreSQL

I build and deploy web applications, from database schemas and APIs to frontend interfaces, authentication, testing and deployment. My recent work includes a school-management platform, a React + FastAPI gradebook, a Thai-learning app and a meal planner.

I previously worked as a data analyst at Knoema using Python and SQL. I currently teach mathematics and computer science, where several of my education projects originated.

Open to full-stack, frontend and Python backend roles — in Thailand, remotely or with relocation.

This is the first version of my portfolio. Older projects remain available here. Visit my current portfolio for recent work and source code.
