About Edsel

Software Engineer with strong experience building scalable backend systems and AI-powered applications. I specialize in Node.js, TypeScript, and cloud-native architectures, with a focus on event-driven systems, APIs, and high-performance services.

I have experience designing and deploying production systems using modern tools such as Docker, PostgreSQL, and distributed messaging systems, as well as integrating large language models into real-world applications through RAG pipelines and AI agents.

I enjoy solving complex technical problems, improving developer experience, and building reliable systems that can scale with growing demand. My work often involves designing clean architectures, optimizing performance, and ensuring observability and reliability in production environments.

Outside of engineering, I’m passionate about technology innovation, cinema, travel, and great food—interests that keep my curiosity and creativity active.
