Background

About David Abreu

Driving technological innovation and operational efficiency is the engine of my career. As a Tech Lead, I've directed teams of 10+ developers in creating and optimizing robust, scalable solutions aligned with business objectives. My experience encompasses defining complex architectures, managing software projects, and implementing artificial intelligence, with a special focus on conversational agents and advanced automations using N8N. I've led the integration of AI through APIs (OpenAI, Claude, OpenRouter) and frameworks like LangChain, LangGraph, and CrewAI, developing intelligent agents and chatbots that enhance business interaction and productivity. In the backend realm, I excel in designing efficient algorithms and building solid systems with Python, Django, NestJS, and GraphQL, applying methodologies like TDD to ensure software quality. My background includes managing architectures in AWS, administering microservices, and optimizing cloud resources. I'm motivated by the challenge of transforming complex processes into clear and effective technological solutions, and I enjoy collaborating with multidisciplinary teams to achieve outstanding results. Always open to new connections and opportunities to create impact through technology.
