About me

Who am I?

Software engineer and tech lead building critical software since 2013 across energy, live broadcast, payments, SaaS and AI. I design scalable, secure systems (cloud migrations, microservices, event-driven platforms serving millions of users) and lead the teams that run them. Today I am a tech lead at Luby, leading client teams, owning architecture and shipping AI features to production. Previously senior software architect at Poli Digital, technical lead at Globo and technical lead of a 9-engineer team at Neoenergia. Postgraduate specializations in software architecture, applied AI engineering and cybersecurity.

How I work

01Reliability first

Most of my results are about systems not failing: fewer incidents, fewer failures, less downtime.

02Architecture that scales people

Guidelines, reviews and mentoring so the team keeps the bar high without depending on one person.

03It counts in production

From live broadcasts to LLM features, the work matters when real users rely on it.

Key achievements

Results, with numbers

Measured outcomes from each company, each one detailed in the experience below.
