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.

How I designed one-tap offline place saving for Apple Watch and iPhone

Pean was never meant to be just another map app. I wanted a faster way to save private places exactly when they matter — from your wrist, without signal, and without friction. Here's the UX and product thinking behind it.
