About

I have been a software developer for over 5 years, working across back-end and front-end.

I helped build, from the ground up, a multi-tenant payments platform for digital course creators: payment splitting across parties, a PSP-agnostic architecture, asynchronous processing, test coverage above 90% and zero critical incidents in production.

Today I am co-founder and full-stack developer of AcheiConsulta, a healthcare appointment booking system. That gave me hands-on exposure to the sector’s flows and domain rules, and a seat in product decisions — not only technical ones.

Continuous learning

I have prior experience with C# from personal game projects. Since 2026 I have been actively studying ASP.NET Core and .NET, applying the grounding in OOP, layered architecture and design patterns I already had from PHP, Laravel and Symfony. I am documenting that process in a series of articles.
