Luis Felipe Duitama Castillo
Systems Engineer
Senior Software Engineer and Full Stack Developer with 12+ years of experience building robust, scalable and maintainable products across complex domains. Core strength in frontend architecture: component systems, TypeScript migrations, clean code boundaries and atomic design, combined with solid backend and cloud capabilities that cover the full delivery lifecycle.
Proven ability to design and implement complex systems, including graph-based routing algorithms, real-time data pipelines, microservice architectures on AWS (ECS Fargate, Lambda, API Gateway), AR experiences and 3D browser rendering via WebGL. Comfortable owning architecture decisions, leading cross-functional teams and going hands-on when it matters.
Operates with a product mindset, pragmatic about tradeoffs, deliberate about long-term maintainability and fast to iterate without sacrificing quality. Experienced with CI/CD (GitHub Actions), containerization (Docker, Kubernetes) and AI-assisted development tooling (GitHub Copilot).
