What I'm looking for

I'm looking for a role where I can own cloud/platform observability or event-driven systems, deliver high-scale reliable services, and grow in technical leadership.

I'm a software engineer with eight years of experience building and operating high-scale applications, focused on cloud, platform and observability. I thrive on end-to-end ownership across the development lifecycle and enjoy learning new technologies to get the job done.

At Mercado Livre Brasil I contributed to an Events team handling about 120 million events per minute and implemented trace analysis using GenAI, plus an MCP to obtain traces and enable user self-service analysis.

I also worked on a Tax Transformation platform integrating sources of truth and tax solutions to monitor and control tax calculation flows, and on checkout and payments initiatives to improve performance, UX and payment capabilities including Pix.

My background spans front-end, back-end and automation (RPA) roles at Hurb, Avanade and GlobalMentor,Inc, with experience in performance optimization, integrations, testing and operational traceability.
