Freelancer profile translated to English.
Back to original languageAbout Lucas
You build fast, but is your backend starting to slow the team down?
I address two concrete problems:
Launch a reliable API without technical debt. I design versioned, secure APIs boosted by AWS, ready to handle the load from the start. No emergency patches six months later.
Connect AI to your business tools. I integrate agents capable of executing real workflows: triage, generation, automation. Not a chatbot, but a component that fits into your existing stack.
Four years of experience on high-volume projects, including a mission in a SAFe environment (~100 developers) of over a year on a complex AWS architecture.
100% remote. Available quickly.
