Summary
Oscar Leche is a Staff Engineer based in the Randstad with 11+ years of hands-on experience designing and shipping full-stack web systems and IoT hardware since 2009. He blends backend expertise in PHP, Node.js, Java and Ruby with frontend UX sensibilities and practical hardware prototyping, having worked with Open Hardware and human-interaction driven electronics since 2012. At Virtuagym he led the financial division to decouple monolith modules into Kafka-driven microservices and guided GraphQL and microservice standardization efforts, and now drives architecture and delivery at Recharge. He’s comfortable across cloud and DevOps tooling (Docker, AWS, GitLabCI) and has repeatedly built resilient integrations with banks and third-party systems. A certified Scrum Master since 2021, he pairs technical depth with strong team leadership and communication skills. Not obvious from the resume: he uniquely combines product-facing UX instincts with low-level hardware prototyping, enabling end-to-end solutions from physical device to cloud service.
