Top SchoolFernando Batista is a pragmatic software engineer with nine years of experience and a six-year coding track record, focused the last two years on backend systems that solve real business problems with minimal complexity.

Fernando combines attention to clean architecture and SOLID principles with hands-on skills in fraud prevention (proof-of-life/face-match) and large-data imports, demonstrating a knack for turning brittle legacy flows into reliable, scalable experiences. Based in São Paulo, he pairs technical rigor with measured creativity and a history of mentoring peers and training new engineers.
