Context
At Braistech, I had one of my first product experiences in a small environment with a distributed level of responsibility. The domain involved crypto-asset contracts and financial movements.
How I worked
I led the structure of the main system with Node.js and NestJS, took part in designing microservices for the business core, and developed Flutter applications. I also built a contract system and worked on payment integrations related to the Binance ecosystem.
I participated in a transition from an MVC organization toward Clean Architecture. The goal was to reduce coupling and make a growing system easier to maintain, while I guided junior developers through the code decisions.
What I took from it
This stage consolidated my interest in backend and architecture. Working across the full product also gave me a full-stack perspective that remains useful in conversations with frontend and product teams.
