I'm Zaid, a full-stack software engineer at PGC Digital working on 10xTA, a multi-service recruitment platform: Fastify APIs, multi-tenant isolation with PostgreSQL row-level security, Azure Entra auth, CI/CD, and AI workflows for resume ranking and interviews. Before that I freelanced for international clients and built the backend of IntelliPrompt, an AI prompt SaaS.

Engineering Notes

Things I've Figured Out

Your RAG demo works. Then someone uploads a 240-page PDF.

Chat-with-your-docs is magic with a 2-page file and falls apart with a real one. The fix isn't a better model; it's the boring pipeline around it.
