Agentic engineering · AI-powered delivery

React Native · React · Next.js · TypeScript · Agentic AI workflows

Based in Lahore, Pakistan, I combine production-grade mobile and web engineering with hands-on agentic systems work: structured instructions, layered prompting, guardrails for agent behavior, and MCP-enabled integrations using Cursor, Claude Code, Codex, and Copilot. Result: faster delivery, stronger review quality, and maintainable codebases as teams scale.

About

Agentic engineering for mobile-first products.

Senior Mobile Engineer with 7+ years shipping React Native and Expo apps end-to-end — TypeScript-first codebases, native modules where needed, and the New Architecture path when teams are ready to invest in long-term performance and maintainability. Strong focus on offline-first design, reliable sync, and apps that stay fast on real devices and flaky networks.

Track record of production-grade delivery — including ~25% app performance gains at Carswitch and ~30% deployment pipeline improvement at TCP Software — without trading stability for speed.

Over the last ~2 years, I have implemented agentic engineering workflows with Cursor, Claude Code, Codex, and Copilot: structured system instructions, repo-level guardrails, reusable prompts, and multi-step review loops that keep delivery speed high without reducing code quality.

I build practical AI execution layers, not tool demos — including instruction hierarchies, rules and constraints for agent behavior, MCP-backed integrations, and reusable hooks/skills for repeatable implementation workflows across teams.
