I strongly believe that Code Quality Matters. I hold myself to high standards even in smaller projects, and in my spare time I keep learning about the latest technologies and architectural design patterns. My favorite topics are performance optimization and concurrency, but I am keen on and proficient in a wide variety of technologies (especially if it has something to do with C# or React which I love). Even though most of my work experience revolves around building ASP.NET Core Web APIs and React/Redux(/TypeScript) frontends, I have had projects involving Windows Forms, WPF, Xamarin Forms / Android, numerous console apps, etc. Besides learning, I also love to share my knowledge with others. My favorite part of leading the development team at my current workplace is being able to mentor junior devs who share my passion in ever improving their design, code quality and performance.

I have spent last 7+ years traveling around the world and writing code for fun and profit as part of the Bakery collective. Before that I briefly worked with a couple of French multinationals immediately after graduating from Telecom Bretagne in a lush green corner of French Brittany. After 3 years in San Francisco followed by 2 years on the road doing the digital nomad thing, I settled down in sunny Portugal where I am currently based. My days are now spent digging into javascript and typescript as well as venturing into the world of Rust. I am most comfortable with **Typescript, Node, React and React Native**. Over past years, I have helped built a number of things, including: a complete suite of software tools for powersports dealerships spanning 3 US states, a companion site and app for a motorcycle coaching association, open source community tools and packages for Meteor web framework and very recently exploring firmware development for a pilot repair facility specialized in bitcoin mining gear repairs in Texas. Most of the gigs I take are characterized by a high level of autonomy, loose specifications and a great deal of uncertainty. These are the kinds of environments I find interesting and motivating. "Strong opinions, weekly held" probably best describes my attitude towards engineering, UX/UI and life in general. I speak 5 human languages (English, Portuguese, French, Ukrainian, Russian) and I have written software using these programming languages (typescript, javascript, rust, python, scala, java, c++, ocaml, prolog, lisp).
