Michael ArizalaFull-stack engineering, from database to deployment.
I work on web applications across the stack — React and Python on PostgreSQL — along with the servers, networks, and pipelines they run on.
Senior Full-Stack Engineer & Mid-Level Infrastructure Engineer
The whole stack, one engineer
My work spans the full stack. The product side is React/Next.js front ends on Python back ends — FastAPI and Django — over PostgreSQL. The operations side is the servers, networks, and pipelines those products run on, provisioned, secured, and maintained.
Those two sides overlap, and I like working where they meet — treating the schema, the API and UI on top of it, the containerized service, the CI pipeline, the firewall and DNS in front of it, and database tuning under load as connected parts of one system rather than separate problems.
