Let’s Build Something Reliable Together

With years of experience across logistics and e-commerce platforms, I help teams and businesses design event-driven backends that hold up under real demand — and understand the operations running around them.

What I Offer

  • Backend & Distributed Systems — Event-driven architectures on Google Cloud, built for traffic spikes and misbehaving third-party integrations.
  • Logistics & E-commerce Expertise — Deep domain knowledge of everything after the checkout: inventory, fulfillment, carriers, and the systems that keep promises to customers.
  • Cross-cultural Collaboration — Years of shared projects with technical and operational teams across Latin America and India.
  • Performance & Architecture Reviews — Measure first, optimize where it matters, verify before shipping.

Why Work With Me?

  • Hands-on experience running high-demand production systems end to end.
  • Domain fluency in logistics and e-commerce, not just their tech stacks.
  • Clear written communication across time zones, treated as part of the engineering.
  • Deliberately boring technology choices that keep systems maintainable for years.

If you’re looking for an engineer, a consultant, or a second pair of eyes on your architecture — let’s talk!
