About Willian Pacheco

I've been working as a backend developer for 5 years and strongly believe in the transformative potential of technology. Early in my career, I gained experience at a real estate startup, contributing to both backend and frontend services. Later, at Solidaridad, I focused on developing APIs with Python and Django. Almost single-handedly, I implemented the entire testing infrastructure and developed security measures that significantly contributed to the app's user growth and improved productivity.Upon joining Mobiplus in 2021, I took on the challenge of starting the development of a new product from scratch. I played a crucial role in building four applications, which grew to have over 200,000 monthly accesses within a year. I've dedicated my efforts to constructing scalable and easily maintainable applications using Domain-Driven Design (DDD) and Test-Driven Development (TDD) architecture patterns.
