Eric V.

Senior Backend Engineer and Software Architect with 15+ years of experience designing, modernizing, and supporting business-critical systems. My strengths include backend architecture, technical problem-solving, production debugging, legacy modernization, API design, systems integration, and clear technical communication. My core stack includes Java 11–21, Spring Boot, REST APIs, Kafka, PostgreSQL, microservices, AWS, Docker, Kubernetes, JUnit, WireMock, SonarQube, and Datadog. I also develop and debug Python and Django APIs using ORM-based persistence, data validation, error handling, and pytest. Selected achievements include modernizing a payment orchestration platform for a major Brazilian retailer, integrating eight payment providers while preserving existing API contracts and implementing idempotency, retries, circuit breakers, Kafka inbox/outbox patterns, and automated contract testing. I also owned the backend of a multi-tenant e-commerce observability platform, delivering live analytics, RBAC, asynchronous AWS S3 reports, SQL and cache optimizations, an anomaly-detection engine covering more than 15 scenarios, and a Spring AI catalog-enrichment pipeline with human approval and external synchronization. I hold a degree in Computer Science from the Federal University of Juiz de Fora (UFJF). I apply DDD, SOLID principles, design patterns, clean-code practices, automated testing, and code reviews to deliver reliable and maintainable solutions. I take ownership from technical analysis through production delivery and can quickly understand unfamiliar codebases, identify risks, explain tradeoffs, and implement pragmatic solutions.
