Alexandre
Jaques.
Full-stack developer based in Lisbon. I build scalable products, AI workflows, and the unsexy plumbing that makes them ship.
Lisbon · 2026An engineer
who runs ops.
Six years at a SaaS startup taught me that shipping is just the beginning. What compounds is the system around it.
I'm a Full-Stack Developer based in Lisbon with an unusual combination: 6+ years of Operations leadership at ChatGuru, founding IntegraNinja to design automation systems for clients in legal, retail, healthcare, and real estate, and hands-on engineering across the React/Next.js stack.
Lately I've been deep in AI Engineering (Claude Code, LLM APIs, agentic workflows) and integrating them into the kind of operational backbones I spent years optimizing by hand. Currently studying AI & Machine Learning Engineering, focused on building scalable, useful systems.
