Senior🎓
Top SchoolDavid Oliveira is a senior Java software engineer with over 20 years in IT and nine years of hands-on experience building backend systems, six of them focused in the financial sector. He specializes in scalable, high-performance distributed architectures (microsserviços, EDA) and cloud-native platforms on AWS/Azure, leveraging Java 21, Quarkus, Kafka and observability stacks to operate mission-critical, compliant systems (PCI-DSS, LGPD). David has a track record of measurable impact—reducing latency by 40%, increasing throughput by 35%, and lowering incident diagnosis time by 45%—and designed event-driven SAGA flows handling 500k+ events/day. He pairs deep technical craftsmanship (virtual threads, native compilation, tracing, structured logging) with product-aware architecture, having led projects that replaced risky third-party dependencies and unlocked new business channels like Pix and Open Finance. Currently driving engineering standards and reusable libraries at Claro Brasil, he excels at aligning governance, security and developer velocity across large-scale transformation initiatives. Colleagues value him for blending full-cycle delivery skills with pragmatic leadership in highly regulated, high-throughput environments.
