Portrait of Andrii Petlovanyi
Andrii Petlovanyi

Full-stack developer based in Ukraine

Product-minded full-stack engineer

I build production-ready web, mobile, and browser-extension products.

I help product teams turn complex ideas into fast interfaces, reliable systems, and user experiences that feel clear from the first use.

About me

Product engineering, quietly polished.

I am a full-stack developer from Ukraine with 7+ years of coding experience and 4+ years in professional product development. I work across web, mobile, browser extensions, and backend services, with a strong focus on product clarity and production quality.

My stack is built around React, Next.js, NestJS, Node.js, Python, FastAPI, Expo, and Swift. I care about products that feel simple because the hard thinking happened underneath: clean flows, stable layouts, strong metadata, readable code, and careful trade-offs.

Born in Morshyn and based in Rivne. Outside of code, I am into spinning fishing, mountains, staying active, and collecting things with a clear point of view: sneakers, caps, and fragrances.

What I build

Production surfaces, not portfolio theater.

Interface systems

Product web apps

Fast, stable interfaces with clean product flows, clear data boundaries, and interaction details that make complex work feel calm.

WebNext.js, React, SEO, accessibility
Mobile UX

Mobile experiences

Capture-heavy mobile flows for real conditions: weak signal, quick saves, Apple Watch moments, and polished native-feeling screens.

MobileExpo, React Native, Swift
Workflow tools

Browser extensions

Focused Chrome extension workflows that stay close to the page, reduce context switching, and turn technical review into clear action.

ExtensionsChrome side panels, audits, automation
Backend systems

APIs and sync systems

Reliable services for sync, validation, metadata, and production behavior under constraints that clean diagrams usually ignore.

SystemsNestJS, Node.js, Python, PostgreSQL

How I think about building products as a developer, not just features

A practical breakdown of how I approach product-minded development: thinking about real users, systems, performance, failure states, and long-term quality instead of only shipping isolated features.
