Faizan AshiqBackend Engineer

Hi, I'm Faizan.

Backend engineer at Levitate Data, working on Cognition. Before that, senior backend and DevOps at Muuve, plus contract and product work across NestJS, PostgreSQL, MongoDB, and AWS.

I build APIs and data layers that stay understandable after the first production incident — clear module boundaries, type-safe interfaces, and deployment patterns that survive real traffic. I write about architecture and production lessons on the blog when something is worth keeping in public.
