Hire the Best TypeScript Developers
in Pakistan

Hi, I'm Ali, a full-stack developer with 6+ years of experience building web applications with React, Next.js, TypeScript, and Node.js. I've worked across SaaS products, e-commerce platforms, and enterprise tools, handling everything from frontend architecture to backend API design (REST and GraphQL) and database work with PostgreSQL and MongoDB. I also work with Svelte and have experience integrating AI workflows using tools like LangGraph and n8n. On Upwork, I've completed 6 projects with Top Rated status. I focus on clean, maintainable code, clear communication, and delivering things that actually work in production, not just in a demo. If you need someone to build or improve a web application, I'd be glad to talk through your project and how I can help. Best Regards Ali H

I help founders and businesses build SaaS products, AI-powered web apps, and MVPs with Next.js, React, TypeScript, and Supabase. 50+ Upwork contracts · 100% Job Success · Top Rated · 1,500+ hours · every project rated 5.0 ⚡ Services I Offer: ✔ SaaS Development — Next.js, Supabase, Stripe subscriptions ✔ MVP Development — idea to working product, fast ✔ AI Integration — Claude API, OpenAI API, RAG, document processing ✔ AI Chatbot Development & AI Agent Workflows ✔ Full-Stack Web Application Development ✔ API Development & Integration — REST, webhooks, third-party services ✔ Marketplace, Booking Platform & Client Portal builds ✔ Front-End Development — React, TypeScript, Tailwind CSS ✔ Back-End Development — Node.js, Python, PostgreSQL ✔ Fixing AI-generated & inherited codebases — audits, refactoring, production hardening 🏆 Recent results: → Two-week build delivered in 3 days, with enhancements ($4,600 project, 5.0) → AI-powered restaurant mapping MVP live in record time (client's words, not mine) → 14-month ongoing frontend engagement, 800+ hours, one client → Full production cutover for a Supabase/Stripe SaaS — zero downtime 💡 Why clients come back: I look at the real thing before I quote — the actual repo, the actual API responses, the actual data. Then you get a straight answer: what's achievable, what it costs, what I'd cut. Working URL early, and it stays working. Scope changes raised the week I spot them, not at handover. And when AI-generated code demos beautifully but can't survive real users — keys in the client bundle, auth that only runs in the browser, no error states — I'm the developer who makes it production-ready without a wasteful rewrite. 🔧 Specialties: Next.js · React · TypeScript · JavaScript · Node.js · Python · Supabase · PostgreSQL · Stripe · Tailwind CSS · Vercel · Docker · SaaS Development · MVP Development · AI Integration · AI Chatbot Development · AI Agent Development · RAG · Claude API · OpenAI API · API Integration · Full Stack Development · Web Application · Workflow Automation 📩 Tell me what you're building — or send the repo if it exists. You'll get a real assessment before either of us commits.

Stop building just another feature. Start automating business outcomes. As a Top-Rated Full-Stack Engineer (100% Job Success) specializing in AI Automation, I bridge the gap between traditional MERN/Next.js development and cutting-edge LLM integration. I don’t just wrap APIs; I build secure, production-grade AI systems that save time, cut costs, and scale gracefully. WHY PARTNER WITH ME? 🔹 Beyond Basic Chatbots: I engineer autonomous AI Agents (LangGraph, LangChain, CrewAI, MCP) that execute complex, multi-step business logic and real-world tasks. 🔹 Data-Driven AI (RAG): I build robust Retrieval-Augmented Generation pipelines using Vector Databases (Pinecone, Supabase) so your AI answers reliably using your private data—with zero hallucinations. 🔹 Production-Ready Architecture: AI is useless if the core app crashes. I ensure seamless integration into robust Node.js and Next.js architectures with enterprise-grade security and multitenant authentication (Keycloak/SSO). 🔹 Human-in-the-Loop Safety: I implement strict guardrails and prompt security to keep your proprietary data protected and your operations reliable. CORE TECH STACK & EXPERTISE: 🧠 AI & LLMs: LangGraph, CrewAI, Custom Agent Workflows, Prompt Engineering, RAG Pipelines. 💻 Frontend: React.js, Next.js, TypeScript, UI/UX optimization. ⚙️ Backend & Databases: Node.js, Nest.js, GraphQL, PostgreSQL, MongoDB, Vector Databases. ☁️ Cloud & DevOps: Docker, Microservices, Stripe API, Keycloak, REST APIs. TYPICAL ENGAGEMENTS: ✔️ Custom AI Agents: Building multi-agent systems for lead generation, data extraction, or automated customer support. ✔️ Internal AI Knowledge Bases: Designing RAG systems to instantly query massive amounts of internal PDFs, contracts, or company data. ✔️ Legacy Modernization: Retrofitting your existing web applications with modern, AI-native capabilities. ✔️ Full-Stack Development: End-to-end development of scalable SaaS platforms from architecture to deployment. My goal is to deliver measurable ROI, not just lines of code. If you want a technical partner who communicates transparently and delivers on time, let’s talk. Send me a message to discuss your current bottlenecks, and let's map out an automation strategy that scales. --- 🚀 EXPLORE MY WORK Please view the Portfolio section below to see live interactive demos of my AI-native applications and my complete 6-year engineering showcase.
