About me

From front-end to my own company

I've been working in software development since 2022. I started in front-end at Opikode and moved to fullstack at Transforma Educação, where I built the Ensina Mais e-commerce, which serves the ZeroHum and ZH+ networks.

In July 2026 I left Transforma to work full time at Techlithy, the company I cofounded. There I lead the development of our CRM for sales teams that sell and support customers on WhatsApp and Instagram. Today Techlithy also runs all of Transforma's IT, so my former employer is now a client.

I like working end to end: understanding the problem of the people who use the system, designing the architecture, writing tested code and shipping it safely.
