Oleksandr Vasyliev

Backend developer with a Node.js, NestJS, and TypeScript stack. Over 1.5 years of commercial experience building and maintaining fintech and logistics projects — including Stripe integrations, WebSockets, and OpenAI API — with PostgreSQL and Prisma ORM.

Alongside commercial work, I independently run several end-to-end full-stack projects - from architecture to production: an online jewelry store built with Next.js and Medusa.js v2 featuring a custom pricing engine and admin panel, and a job board aggregator with data deduplication algorithms (NestJS + Prisma + PostgreSQL + Next.js).

I write clean, maintainable code, design REST APIs, and work confidently with third-party integrations. Reliable with deadlines and communication, comfortable working remotely across time zones.
