Rockstar🎓
Top SchoolWashington Botelho is a Senior Software Engineer with 16 years of experience who evolved from front-end work into back-end and infrastructure-focused engineering, primarily using Ruby and Elixir. He’s driven migrations and performance improvements at scale—rewriting billing and checkout systems, moving services from monoliths to microservices, and optimizing critical flows to reduce load by over 40%. A pragmatic maintainer and open-source contributor, he’s improved Java frameworks like VRaptor (serialization, validation, dependency upkeep) and publishes work on GitHub while founding startups and a design/music initiative. Comfortable across cloud and queueing technologies (Kafka, RabbitMQ, AWS) and payment integrations (Stripe, DocuSign, Iugu), he blends product-minded engineering with operational reliability. Based in São Paulo, he pairs deep technical breadth with a collaborative mentoring history, often surfacing unexpected wins by turning refactors and migrations into measurable business impact.
