What I'm looking for

I’m looking for remote Engineering Manager or Technical Lead opportunities where I can lead teams, shape technical direction, and drive delivery for scalable, reliable systems. I’m especially interested in backend-heavy, platform, and distributed systems environments where leadership, ownership, and business impact matter more than individual contributor scope.

Engineering Manager focused on building and scaling distributed systems that support real business operations. I lead teams at the intersection of technical depth and delivery, aligning engineering with business needs and ensuring complex systems work reliably in production.

My background spans business-critical platforms, fast-paced MVPs, and data-intensive systems, with a strong emphasis on execution, ownership, scalability, and measurable impact. I have led the delivery of high-impact products, including a platform for Brazil’s free energy market that reduced processing time from weeks to hours for around 350 clients, and an MVP launched in three months in a fast-paced environment.

My core strengths include engineering leadership, distributed systems, software architecture, backend systems, scalability, and reliable execution.
