About Me

Valentina Koniukhova is a Flutter mobile developer based in Buenos Aires, Argentina, with over 5 years of cross-platform iOS and Android experience. She is the creator of the open-source RollerList Flutter package and has shipped apps including AimYear, Focido, despues.care, and CABA-test to the App Store and Google Play.

Hello! I'm Valentina, a passionate mobile developer specializing in Flutter and cross-platform development. I build elegant, performant apps for iOS and Android while solving complex problems through clean, maintainable code.

I received my degree in Russia and worked as an IT lecturer at a university, teaching the next generation of developers. I mastered Android native development through Udacity with a Google scholarship, and I've been working with Flutter since it became production-ready over 5 years ago.

Currently based in Buenos Aires, Argentina, I contribute to the open-source community through packages like RollerList and share my knowledge through technical writing on Medium.

💼Featured Projects

A selection of projects I've built, from open source packages to mobile apps.

Worklore story feed — short developer stories agents can reproduce

Worklore

Web Platform

A library of short, honest developer stories about what people actually built with their AI agents. Every story is executable — a reader's agent fetches the "Reproduce this" contract, applies it to their own project, and reports back, so stories carry verified reproduction counts.

Safety Control offline-first industrial inspection app

Safety Control

Client App

An offline-first field-inspection app for industrial safety, built for a client with an existing web platform. Inspectors download the day's tasks in one morning sync, complete checklists and photos fully offline on site, and upload results after each inspection. I designed the custom sync protocol over the client's browser-oriented API.
