Hey hey!
I'm Andrii Petlovanyi
Full Stack dev from Ukraine

About me
I'm a Full Stack Developer with 7+ years of coding experience and 3+ years in professional product development. I work across the full spectrum — web, mobile, browser extensions, and backend services.
My stack is built around the JS/TS ecosystem (React, Next.js, Nest.js, Node.js) extended with Python and FastAPI for backend-heavy tasks, and Expo / Swift for mobile. I've shipped products in e-commerce, healthcare, and fintech.
Born in Morshyn, based in Rivne, Ukraine. Outside of code I'm into spinning fishing, fast cars, psychology, and mountains.
What I build
Web Applications
Full-cycle web apps — from architecture to deployment. React, Next.js on the front, Nest.js / FastAPI on the back.
Mobile Apps
Cross-platform with Expo / React Native, native iOS with Swift. From MVP to production.
Chrome Extensions
Browser extensions that integrate into existing workflows and automate routine tasks.
APIs & Microservices
REST and event-driven services with Node.js, Nest.js, Python. Scalable, documented, production-ready.
