What I'm looking for

I'm looking to work remotely with US or EU engineering teams on scalable, high-performance cloud-native systems, contributing backend architecture, event-driven services, performance improvements, and hands-on technical delivery.

Based in Buenos Aires, I work remotely with international clients through my US entity, Kayak Consulting LLC, adapting my schedule to US and European business hours while ensuring strict NDAs and full client IP ownership compliance.

With over 20 years of hands-on experience, I don't just design architectures; I integrate into the engineering team and stay in the technical work, refactors legacy bottlenecks, and solves complex backend problems from the inside. Throughout my career, I've worked with high autonomy across fintech, telecom, and supply chain, scaling and stabilizing high-traffic platforms.
