    πŸ‘‹ Hi, my name is Guillermo Zevallos

Connect with me:

πŸš€ Software Engineer with 5 years of experience building backend services and web platforms for banking and fintech. I work with Java and Spring Boot on the backend β€” microservices, DDD, CQRS, event-driven design with Kafka β€” and with React, Next.js and Angular on the frontend. I design serverless architectures on AWS (Lambda, Step Functions, API Gateway, DynamoDB) with infrastructure as code using AWS CDK, and I recently led the rollout of an organization-wide AI engineering harness based on spec-driven development.
