About

How I like to work.

I’m a backend-focused PHP/Laravel software engineer from Lahore, Pakistan, with 4+ years of professional experience and practical full-stack delivery responsibility. I care about correctness under load: safe retries, stable ordering, auditability, and clean boundaries between modules. On product work, I optimize for long-term maintainability, clear ownership boundaries, and software that survives real operational use.

My core work combines Laravel application architecture, SQL data modeling, Redis-backed processing, webhooks, and production operations. Python/FastAPI integrations complement that PHP/backend foundation.

What you get

  • Architecture that supports web clients, APIs, jobs, integrations, data, storage, and deployment.
  • Resilient background processing: throttling, retries, resumability.
  • Security-first integration patterns (no leaked keys).
  • Performance-aware DB work and caching.
