Based in Rawalpindi, Pakistan, currently building multi-tenant SaaS platforms at Tango Sys.
I work across React, React Native (Expo), Python/FastAPI, LangGraph, and Supabase, and I like shipping AI-assisted products fast - from concept to production. Recent work includes an HR ATS platform using GPT-4o for CV parsing and candidate scoring, multi-agent RAG pipelines, and a lead-gen system delivering 4,800+ structured leads a week.
What I work with: Generative AI, LLMs, RAG, LangChain, LangGraph, Prompt Engineering, Vector DBs, React, React Native, Angular, FastAPI, Python, TypeScript, JavaScript, SQL, Supabase, Firebase, Azure AI
A few things I've built:
• HR ATS & Attendance System — GPT-4o powered CV parsing, candidate-job scoring, and payroll management (live in production) • LeadScraper - 8-agent SaaS lead-generation pipeline with a Chrome extension and email enrichment • KaamGraph - autonomous 5-agent workforce-matching pipeline for bilingual (Roman Urdu/English) service matching • Investment Analyst Report Generator - 3-agent system generating real-time investment summaries • Agro World App — AgriTech-FinTech app connecting farmers to market rates and micro-financing, live on the App Store and Google Play
