You will get a Point of Sale & Business Management System
Rising Talent
Project details
Your business is running on spreadsheets, manual invoices, and disconnected tools costing you money every day through inventory errors, missed payments, and hours of manual reconciliation.
I build modern, web-based Point of Sale and Business Management Systems that replace all of that with one unified platform. Real-time inventory tracking, sales and purchase processing, double-entry ledger accounting, supplier and customer balance sheets, employee payroll management, and direct thermal receipt printing — all tailored to your exact business workflow.
Built on Next.js 15, PostgreSQL, and Prisma ORM with 100% TypeScript — this isn't a generic template or off-the-shelf installation. Every system is custom-built from scratch for your specific business operations, designed to handle real retail and wholesale environments.
What you get: a complete, production-ready business management platform with full source code ownership — not a subscription to someone else's software.

Full Stack Developer | Next.js | GenAI | SaaS | MVP | Python | AWS
Lahore, Pakistan - 1:51 am local time
Whether you're a startup founder who needs an MVP shipped in weeks or an enterprise team modernizing a complex workflow, I bring the same thing every time: clean architecture, production-ready code, and a developer who understands your business goal, not just your tech stack.
🤖 AI & Generative Technology
I don't build ChatGPT wrappers. I build real AI systems.
My AI work spans RAG pipelines with LangChain and knowledge-base ingestion, OpenAI streaming with function calling, Claude API integrations, confidence-aware research agents, and intelligent document processing. I've shipped AI systems that reason, retrieve, and respond, running in production for real users.
For Voice AI specifically, I work with the full modern stack:
→ OpenAI Realtime API — low-latency voice conversations with real-time transcription
→ Whisper AI — speech-to-text for transcription pipelines and audio processing
→ ElevenLabs — natural voice synthesis and text-to-speech integrations
→ Vapi / Retell — voice agent frameworks for automated phone and web conversations
→ Tavus / HeyGen — realtime avatar generation and their integration.
If your product needs to speak, listen, or think, I've built that.
🚀 MVP Development
I understand what founders actually need: something real, fast, and scalable enough to grow. I've built MVPs from scratch that include authentication, payments, AI features, and cloud deployment, delivered in weeks not months. I know which corners are safe to cut and which ones will cost you later. That judgment is what separates an MVP that launches from one that gets rewritten.
🏥 Healthcare & Compliance
I've built a healthcare onboarding automation platform where staff could digitally review compliance documents, complete multi-step structured forms, and move through fully auditable automated workflows. This required:
→ WCAG 2.2 AA accessibility standards throughout
→ Semantic HTML5 with proper ARIA attributes for screen-reader compatibility
→ Keyboard navigation and focus management across complex multi-step flows
→ Secure form handling and data integrity for sensitive information
Building for healthcare taught me that great frontend is never just visual — it's compliant, accessible, and trustworthy.
⚙️ Full Stack Engineering
On the frontend I work with React, Next.js, and TypeScript, building component architectures that scale, performance-optimized interfaces, and pixel-perfect Figma-to-code implementations. On the backend I design REST APIs with Node.js and Express, handle complex database schemas with PostgreSQL and MongoDB via Prisma ORM, and integrate third-party services cleanly and reliably.
☁️ Cloud & Serverless Architecture
I work daily on production AWS Serverless architecture Lambda functions, API Gateway, and S3. Beyond serverless, I handle deployments across AWS Amplify, EC2, EKS, and self-hosted environments with Coolify, whatever your infrastructure requires. I build backends that scale cleanly and keep cloud costs predictable as your product grows.
💳 SaaS & Payments
I've implemented Stripe end to end, subscriptions, Connect payouts, webhooks, invoice generation, and usage-based billing tied to AI token consumption. If you're building a SaaS product that needs to charge users, I've solved that problem completely.
