Top Rated
Project details
This catalog specializes in creating modern, high-performance web applications with Next.js, leveraging Server-Side Rendering (SSR) for speed and SEO optimization for better visibility. I build apps that are lightning-fast, scalable, and deployment-ready, ensuring they meet both technical and business goals.
With expertise in Next.js architecture, I combine React’s flexibility with server-side rendering and static site generation to deliver apps that load instantly, rank better on search engines, and provide a seamless user experience.
Benefit from:
✔️ Next.js web app development (modern & scalable)
✔️ Server-Side Rendering (SSR) for performance
✔️ SEO-optimized structure for better rankings
✔️ API integration & backend connectivity
✔️ Responsive & mobile-friendly UI/UX
✔️ Deployment support (Vercel, AWS, Azure, etc.)
✔️ Optimized code for speed & scalability
I ensure your Next.js application is not only visually appealing but also built for speed, search visibility, and growth.

Rawalpindi, Pakistan - 5:55 pm local time
WHAT I DO
1) AI INTEGRATION INTO YOUR EXISTING PRODUCT
AI chatbots and assistants, RAG pipelines (LangChain, pgvector, Pinecone) over your documents with citations, semantic search, AI agent workflows, voice features, image and content moderation, computer vision — wired into your real app with streaming UI, auth, per-user usage caps, an evaluation set and LLM cost controls. OpenAI API, Anthropic Claude, Gemini. Production behavior, not a demo.
2) FINISH & PRODUCTIONISE AI-BUILT APPS
You built it with Lovable, Bolt, Cursor, Replit or FlutterFlow — or a previous developer left. I audit the code and data layer (auth, Supabase RLS, security, secrets), build the missing backend, fix crashes and performance, and get it through App Store and Google Play review. Audit in 3–5 days, fixed quote after.
3) AI-FIRST MOBILE APPS & MVPs
Flutter mobile app development (iOS + Android) with a FastAPI or ASP.NET Core backend, admin dashboard, Stripe payments, push notifications, analytics and store release — with the AI layer designed in from day one.
4) BACKEND & CLOUD FOR AI APPS
Python/FastAPI and .NET REST APIs, PostgreSQL/pgvector, SQL Server, MongoDB, Redis, Firebase, Supabase; deployment on Azure and AWS with Docker, Kubernetes and CI/CD; monitoring, LLM latency and cost tuning.

HOW I WORK
• Send the job post, the repo, or a short Loom → you get a 1-page plan (scope, architecture, milestones, risks) and a fixed quote within 24 hours.
• Milestone-based delivery, daily async updates, weekly demo. Your repo, your cloud — source code, documentation and CI/CD included.
• Security by default: role-based auth, secrets management, RLS, store compliance. NDA welcome.
• 30+ hrs/week, replies within 2 hours (evenings US, mornings EU/Gulf).
Good fit: a product that exists (or an AI-built prototype that needs to become real) and a budget of $1,500+ or $45+/hr. Not a fit: sub-$500 tasks, "clone X", UI-only work.
Send the post or a Loom — plan and quote within 24 hours.
