Full-stack & AI engineer in Lahore, Pakistan. I build the load-bearing half — the billing, the queues, the real-time, the data you make decisions on.

What it does for a business
Same work either way. This just changes how much of the machinery I show you.
I build the software your business actually runs on.
SaaS platforms, AI features that do real work, and automation that takes the busywork off your team. Subscriptions that bill correctly, email that reaches people, dashboards that tell you the truth. I take a product from an idea to something live, then keep it alive — and you get one person accountable for the whole stack instead of a handoff between three.
Full-stack developer, two years shipping production platforms on MERN and Next.js.
Currently at Hashlogics, delivering client platforms end to end — architecture, build and client communication. Next.js and React on the front; Node, Express and Prisma over PostgreSQL, plus Supabase, on the back. The specialism is AI-powered products and workflow automation: RAG assistants, OpenAI pipelines and multi-tenant SaaS, with integration work across Stripe, Mailgun and twenty-odd third-party services.
I like the parts that page you at 3am.
Webhook idempotency. Migration drift on a database you cannot reset. An N+1 hiding behind a nice-looking repository method. A require cycle that only bites standalone scripts. I write the boring layers deliberately — repository and service split, Zod at every boundary, one transport for email, observer taps rather than call-site edits — because that is what makes the interesting layers survivable.
Services
Four kinds of work, each one backed by projects running in production today.
AI features & agents
Assistants, report generation, retrieval over your own data — AI that does real work inside the product, with the guardrails production needs.
Automation & integrations
n8n workflows and the glue between CRMs, Stripe, Google, Zoom and WhatsApp, so work moves on its own instead of being copied by hand.
Rescue & maintenance
Take over an existing app, find what is fragile, fix it and keep it running — security and access testing included.
