backend & route-optimization · reliability engineering · MG / Brazil

I design and run the backend that keeps freight moving at scale — from a fiscal-document pipeline holding a >99% generation SLA to the route-optimization core of a logistics platform. Mechatronics and firmware roots; comfortable from the silicon to the distributed system.

Profile

What I'm responsible for

Tech Lead at Uello, a logistics startup, where I own the backend and QA tracks. I pair strategic leadership with hands-on engineering, and I optimize for systems that stay up, stay observable, and stay easy to ship to.

01

Reliability & SLOs

Led a full refactor of the financial and fiscal flow to a document-generation SLA above 99%, with observability and monitoring built in via NewRelic.

02

Route optimization

Own the route-optimization system at the core of the platform — infrastructure, service stability, and the developer experience around it.

03

Platform & DevEx

Build internal tooling that streamlines deployment and observability, and fold quality into CI/CD so teams move fast without breaking production.

Experience

The route so far

A path from firmware and embedded electronics to leading backend systems in logistics — each stop a waypoint.
