I've been working as a developer professionally for 10+ years and I enjoy developing complete products from the ground up, including the full tech stack and design.

The last couple of years I've been dedicated to working almost exclusively with React and Node.js full time in large scale projects.

Before working as a consultant I launched a streaming music service focused on electronic music with two friends/co-founders. I was responsible for everything technical including backend/frontend and providing reliable hosting for millions of songs.

We secured music licensing deals from several major music labels such as Sony Music and raised multiple rounds of funding.
