I'm Lourenzo Ferreira — a Senior Software Engineer and Solutions Architect based in São Paulo, Brazil, with over 20 years of experience building robust, high-availability technology solutions.
My work spans the full spectrum of modern software engineering: from designing high-performance APIs and event-driven architectures to building complex rule engines, orchestrating business processes, and integrating systems across cloud infrastructures.
I've had the privilege of contributing to mission-critical systems at some of Brazil's leading financial institutions — including Santander, Bradesco, BTG Pactual, Banco BV, and Remessa Online — as well as technology companies like iFood, Passei Direto (UOL EdTech), and international ventures through Rocket Internet.
Through Lourenzo Ferreira Tech, I offer consulting, development, and technical leadership services to companies of any size. Whether you need to modernize a legacy system, integrate AI into your workflows, build a scalable fintech API, or need an experienced technical leader for your engineering team — I'm here to help.
I believe in building systems that are not only functional but resilient, well-tested, and designed for the long term. Every engagement starts with understanding your business needs and ends with production-grade, battle-tested solutions.
