Technical depth.
A product eye.

I hold a BS in Information Technology from the University of the Punjab. Day to day I own Laravel orchestration — queues, jobs, scheduling, multi-tenancy — plus Python automation and Nginx delivery with CI/CD.

Recent focus: Ollama local models for cost-efficient bots, JazzCash payment rails, and FBR tax automation for Pakistani retail.

03

05

DevOps & delivery
