01Profile
A product developer with real, practical range.
With over 6 years of hands-on engineering inside software houses and fast-moving product teams, I bridge deep technical execution with real commercial empathy. Having built enterprise ERPs, cross-platform mobile apps, 3D geospatial platforms, and real-time AI tools, I am now focused on solving the fundamental commerce bottleneck for Pakistani businesses: giving any physical store an automated digital identity and selling engine operated entirely through WhatsApp.
Creator of Karobari — enabling Pakistani merchants and local businesses to create an automated digital store and manage multi-channel commerce with nothing but WhatsApp voice notes and text in Urdu or English.
Conversational AI & Product Founder
Creator of Karobari — pioneering zero-friction WhatsApp commerce for emerging market businesses through voice and AI.
Full-Spectrum Technical Range
Fluently architecting across React 19, Next.js 16, Convex, React Native, Electron, Docker, and LLM agent orchestration.
Commercial & Operational Empathy
Focuses on the bottom-line: fee collections, revenue dashboards, checkout conversions, and frictionless user adoption.
02What I build
Complete business systems, not isolated screens.
I build the workflows around the screen too: data, roles, automation, integrations and the launch details that make software actually usable.
Conversational Commerce & WhatsApp AI
AI agents, automated storefront generators, billing engines, and inventory managers driven purely by WhatsApp voice and text in Urdu and English.
Full-Stack SaaS & Operations ERPs
Scalable multi-tenant cloud platforms, real-time reactive databases (Convex), billing pipelines, and executive dashboards built for daily high-concurrency usage.
Cross-Platform Mobile Applications
Production React Native and Expo applications with offline caching, hardware integrations (BLE, GPS, Cameras), and verified store distribution on iOS and Android.
Desktop Automation & Native Workstations
Electron and desktop utilities bridging local operating systems, hardware peripherals, WhatsApp automation engines, and cloud control panels.
03Featured work
Products shaped around operations, revenue and daily use.

05How I work
A direct path from workflow to working software.
1. Deconstruct the Real Workflow
Start with how real people and merchants already work. Identify where time is wasted, how customers communicate (e.g., WhatsApp voice notes), and what data matters.
2. Rapid High-Leverage MVP
Ship the smallest, complete system that creates immediate commercial value, tests market adoption, and solves the core bottleneck without feature bloat.
3. Hardened, Maintainable Scale
Build with type safety, clean schemas, reactive real-time backends (Convex/Prisma), and automated messaging pipelines ready to handle daily production scale.
