Lahore, Pakistan - 9:27 pm local time
I'm a senior full-stack engineer and tech lead with 11+ years of shipped production systems, web platforms, multi-tenant SaaS, mobile apps, and AI features that make it past the demo stage. I work at the system level: architecture, database design, APIs, frontend, deployment, and the monitoring after launch.

A recent proof point: I founded and solo-built TeleVox AI, a production voice-AI SaaS that answers business calls in about 0.7 seconds, the live demo you can talk to is in my Portfolio below.

WHAT I DO
- Full-stack web applications: React, Next.js, Angular on the front; Node.js, NestJS, Python on the back
- SaaS platforms and CRMs: multi-tenant architecture, billing, role-based access, real-time dashboards
- Mobile: React Native and Flutter, store-ready
- AI features and agents: LLM integrations (OpenAI, Gemini), RAG knowledge bases, chatbots, voice agents
- Cloud and DevOps: AWS, Azure, Docker, CI/CD, observability

SELECTED WORK
- Pepperstone: React front-ends for a global trading platform serving millions of traders; compliance-grade authentication
- Optima CRM: real-estate agency platform on the MEAN stack; the client reports a 40% revenue increase after adoption
- CallAgent AI: conversational AI for call centers with real-time human transfers and campaign automation
- My Lobby: visitor management with QR access, real-time dashboards, and an AI call agent
- LodgeIntel: real-time BI for hospitality groups with live revenue and occupancy dashboards
- TeleVox AI: my own voice-AI SaaS: phone, WhatsApp, and web channels, mid-call bookings, outbound campaigns

STACK: TypeScript, JavaScript, Python, React, Next.js, Angular, React Native, Node.js, NestJS, Express, PostgreSQL, MongoDB, MySQL, OpenAI, Gemini, Twilio, LiveKit, Deepgram, Supabase, AWS, Azure, Docker, Stripe, GraphQL, Socket io

HOW I WORK
Clear written communication, clean maintainable code, honest estimates, and no surprises. NDA-friendly, comfortable leading a build or embedding into your team, with overlapping hours across US, UK, EU, and UAE time zones.

If you need a senior engineer who thinks in systems and delivers business results, not just tickets closed, send me a message. I usually reply within hours.
