About Oscar

Oscar Chavez - Cloud Infrastructure & DevOps Consultant



About


I am a Cloud Infrastructure and DevOps specialist who helps startups and scale-ups build reliable, cost-effective systems. As a founding DevOps engineer at the Middle East’s leading open banking provider and technical leader at fintech startups, I bring both strategic thinking and hands-on expertise to help companies scale their infrastructure while reducing costs and complexity.

What I do


-I dramatically reduce cloud costswhile improving performance. Through strategic refactoring and optimization, I’ve helped companies cut infrastructure spending by up to 70%
-I eliminate deployment frictionby building modern CI/CD pipelines that transform release cycles from weeks to minutes
- **I architect for reliability at scale**, maintaining >99.9% uptime for mission-critical APIs serving hundreds of thousands of users, even through major infrastructure migrations
-I create self-service infrastructure platformsusing GitOps and Infrastructure-as-Code, empowering development teams to move fast without compromising security

Who I am

- I’m a pragmatic problem-solverwho focuses on business impact first, technology second. I align technical decisions with company goals, whether that’s passing security audits or reaching market coverage targets
- I thrive in high-stakes environments, managing critical infrastructure for financial services in regulated markets and leading operations at fast-growing startups
- I’m passionate about developer experience. The best infrastructure is invisible infrastructure that just works, letting teams focus on building great products
