Lahore, Pakistan - 1:37 pm local time
With 13+ years of software engineering experience, I build and ship AI-powered products, SaaS platforms, automation systems, mobile applications, enterprise software, and real-time media systems.

I work across Node.js, React, Next.js, Python, FastAPI, TypeScript, APIs, AI integrations, cloud infrastructure, and production deployment. Whether you are building a new product or improving an existing codebase, I can take ownership and deliver independently.

I build practical AI software that connects models to business data, documents, APIs, SaaS platforms, media pipelines, and real-world workflows.

𝐂𝐨𝐫𝐞 𝐄𝐱𝐩𝐞𝐫𝐭𝐢𝐬𝐞

✅ AI SaaS, RAG applications, AI agents, and knowledge systems
✅ Business automation for documents, CRMs, reporting, APIs, webhooks, and internal workflows
✅ Full-stack applications with Next.js, React, Node.js, Python, FastAPI, PostgreSQL, Supabase, MongoDB, and Redis
✅ Enterprise systems including custom dashboards, CRMs, ERPs, marketplaces, and API integrations with scalable architecture
✅ Real-time and media systems using WebRTC, LiveKit, WebSockets, FFmpeg, HLS, and RTMP
✅ Mobile apps with React Native and Flutter
✅ Electron desktop apps and browser/workflow automation with Playwright, Puppeteer, Apify, and n8n
✅ Chrome extensions, REST and GraphQL APIs, microservices, and event-driven architecture

𝐇𝐨𝐰 𝐈 𝐖𝐨𝐫𝐤

I start with the business goal and technical requirements, then choose the architecture based on what the product actually needs.

You get a senior engineer who works independently, understands existing codebases quickly, communicates clearly, and owns delivery.

I can build end to end, take over an existing codebase, improve systems, or work alongside your team.

If you are building an AI product, automating a business process, developing a SaaS platform, enterprise system, API, or real-time application, send me the details and I will explain the most practical technical approach.
