Alejandro Padilla
Full-Stack Developer · Python & TypeScript
I design, ship, and operate full-stack systems in production — FastAPI and Next.js services, asynchronous processing, and LLM-backed automation where it measurably removes manual work.

$ about-me
Technical execution with a business purpose.
I'm Alejandro Padilla, a full-stack developer and Computer Science student at Universidad Nacional de Loja in Ecuador.
I build and operate systems that real clients depend on: domain modeling, backend services, asynchronous job processing, authentication, automated tests, and deployment. I also apply AI as an engineering tool — LLM-backed automation and agent-orchestrated development workflows — when it removes measurable manual work.
