$100k+ earned on Upwork | 1,000 + billed hours | Building production-ready AI SaaS & Full-Stack products with a proven 5-star client history.
If you shoot me a invitation or direct message i'll send you a personalized loom video back on how i may be able to help you!
Your AI SaaS works in the demo, then breaks the moment real users hit it. I build production ready web applications and Full Stack SaaS platforms that don't, the kind running production right now, moving 10,000+ messages a day at 99% delivery and saving one client $200k+ a year. From AI automation and RAG systems that don't hallucinate to scalable backend systems, multitenant architectures and secure enterprise software,I build products that stay reliable as they grow.

I build web scrapers and backend systems that run reliably in production, so you're not the one debugging them at midnight with AI/LLM integrations layered in where the project calls for it.
I work with startups and growing teams who need something specific built and shipped, not a generic dev shop. Scraping pipelines, backend APIs, automation workflows, AI integrations I've built all of these in production, not in a tutorial.
A few things I've actually shipped:
✅ Scraped 10,000+ business records with Python/Selenium, piped through AWS
Lambda into DynamoDB and RDS running unattended for a live client
✅ Built a Pinecone + LangChain recommendation engine with semantic search
over embedded text data
✅ Built a real-time chat system: WebSocket gateway + RabbitMQ across
microservices
✅ Built a gRPC payment microservice for secure transaction handling
✅ Shipped NestJS REST APIs with JWT auth, cutting response times through
clean query and caching design
✅ Ran a Python/Selenium scraping framework for a German B2B SaaS company
(Markt-Pilot) still an active client
100% Job Success Score. Top Rated. Karachi-based, but I work async-friendly
hours for US/EU teams.
If you've got a backend, scraper, or AI workflow that needs to actually work
in production send me the details and I'll tell you straight whether it's
a good fit, no sales pitch.
EXPERTISE: NestJS | Node.js | Python | Selenium | BeautifulSoup | AWS

🚀 Over 14 years and 320+ shipped products, we've helped startups and scaling businesses turn ideas into fast, profitable digital platforms. Our team has delivered 180+ custom web applications, 60+ mobile apps, and 40+ AI-powered software systems, each engineered to perform from day one and scale without friction.
I lead a senior full stack developer team with deep roots in both frontend and backend engineering. We've driven results that speak for themselves: load times reduced by up to 73%, API response times cut from 1.8s to under 200ms, and clients growing revenue by 3-5× after launching platforms we built. Whether the project calls for a dedicated React developer, a WordPress developer, a mobile app developer, or a complete full stack developer team owning end-to-end delivery, we've executed at scale across every major industry.
E-commerce and growth systems are core to what we do. Our full stack Shopify builds have processed $2M+ in Year 1 GMV. Custom React Shopify frontends we've engineered improved client conversion rates by 38%. Full stack ecommerce platforms we've shipped now serve 50,000+ daily active users. Full stack SEO is baked into our engineering process from day one, server-side rendering via React Next.js, structured data, Core Web Vitals optimization, helping clients rank on Page 1 for 400+ competitive keywords within 6 months of launch. SEO React architecture isn't an afterthought in our workflow; it's a first-class engineering requirement built into every frontend system we deliver.
Our React developers architect scalable component libraries used across teams of 15+ engineers and consistently deliver UI scoring 90+ on Lighthouse performance audits. On mobile, we've shipped 60+ cross-platform React Native mobile applications with 800,000+ combined downloads and an average 4.7★ app store rating. Every React Native developer on our team works across the full product lifecycle, architecture, development, App Store submission, and post-launch iteration, using React Native Expo for fast, reliable iOS and Android deployment.
Our WordPress developer practice has produced 90+ websites, from editorial platforms handling 500,000+ monthly visitors to WooCommerce stores carrying 10,000+ SKUs. Every website that leaves our team is performance-tuned, SEO-ready, and built so non-technical editors can manage it without touching a line of code.
The full stack developer team I lead operates across the entire technology stack. On the frontend: React, React TypeScript, React Next.js, Vue.js, Webflow, Tailwind CSS, and Bootstrap.
On the backend: Python, FastAPI, Django, Node.js, Laravel, PHP, REST APIs, and GraphQL.
Our Python developer capability covers data pipelines processing 2M+ records daily and backend APIs handling 100,000+ requests per hour. Infrastructure runs on AWS, Firebase, and Supabase, with CI/CD pipelines that compress deployment time to under 8 minutes.
We've delivered software across 15+ verticals including AI platforms, fintech, healthcare, legal document automation, education LMS, HR software, social media products, automotive ERPs, manufacturing systems, and digital marketing platforms with Meta, Google, and TikTok integrations.
Our AI-powered platforms have reduced client manual review time by 65%, improved lead qualification accuracy by 44%, and automated 1,200+ repetitive operational tasks per month.
The engagement model flexes to fit what you actually need. A solo React developer who owns frontend delivery end-to-end and ships a complete system in 6 weeks. A senior web developer who steps into an existing codebase, stabilizes releases, and reduces critical bug rates by 80% within 90 days, something we've done for 25+ companies. A full stack developer team scaling from 2 to 14 engineers mid-project without missing a single deadline. We've operated in every configuration and delivered in all of them.
Whatever the scope - a new website, a SaaS product, a scalable React frontend, a CMS platform, cross-platform mobile apps, or a complete backend system, my team has the full stack developer depth, the React developer precision, the web developer range, and the product engineering experience to build it right the first time.
14 years. 320+ products. Millions of users served. Let's build yours.
