What I'm looking for

I'm available for remote work in Mexico.

At Turing, I engineered Python backend services for data pipelines and improved application performance by 20% through PostgreSQL and MySQL query tuning and Redis caching. I also designed async backend architecture with Kafka, raising throughput by 35%.

At Petco México, I overhauled storefront rendering and caching, reducing page load times by 30% and boosting conversion by 12%. I built web experiences with Next.js and React and contributed to modernizing the storefront into a headless architecture.

At Katana Inu, I architected a gaming platform supporting 100K+ concurrent users and helped cut API latency by 30%. I built distributed microservices and directed twelve or more engineers across teams delivering major features.

Earlier, at Teahouse Finance and Sam's Technology Company, I worked on trading interfaces, enterprise applications, and APIs. I bring experience across backend, frontend, data, and deployment work, and I write automated integration tests before work ships.
