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, mountains, and staying active. I enjoy things that require focus, patience, and a clear mind.
I also enjoy collecting things I genuinely like: sneakers, caps, and fragrances. For me, it's not just about owning them, but about building a sense of taste and paying attention to details.
That same mindset carries into my work: I don't just build products — I refine them until they feel simple, clean, and right.
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.
