Job Success
Islamabad, Pakistan - 7:48 am local time
I am a Top-Rated Plus Full-Stack Developer on Upwork with over 1,000 hours billed, 10+ years of experience, and a consistent 5-star track record. Whether you need an MVP from scratch, require scaling for a product that has found traction, want to modernize a legacy platform, or need AI integration into an existing system, I design the right path across product architecture, data architecture, integrations, and production rollout.
Core Technical Delivery:
Full-Stack Web Apps: Extensive experience building scalable applications using React, Next.js, Node.js, TypeScript, and Python. I implement clean architecture deployed on AWS and Vercel for industries ranging from health and fitness to custom dashboards.
SaaS Platforms & SaaS Development: Building multi-tenant SaaS systems, role-based SaaS workspaces, and HIPAA-compliant SaaS platforms. All SaaS solutions are white-label ready with Stripe subscription billing integrations.
MVP Development: Rapidly launched MVPs optimized for speed and scalability. I leverage Node.js, Next.js, PostgreSQL, Supabase, and MongoDB database design to ensure your MVP architecture scales without rewrites.
AI Integration & AI Agent Development: Advanced Retrieval Augmented Generation (RAG) pipelines, LLM integrations (OpenAI API, GPT-4, LangChain), Python-powered AI agents, and multi-agent systems. I build AI voice agents for customer support, sales automation, and onboarding, embedded directly into your SaaS.
API Development & API Integration: Scalable REST and GraphQL API development using Node.js and TypeScript. I specialize in robust API integrations with Stripe, Twilio, OpenAI API, and other critical SaaS APIs.
Backend Architecture & Automated Workflows: Real-time backend development with Node.js, Redis, Docker, and CI/CD pipelines. I also deploy automated workflows using n8n for FinTech, E-Commerce, and health platforms.
Live Streaming & Real-Time Apps: WebSocket-powered real-time applications, Next.js live streaming platforms, and event-based backend architectures.
It is not just about shipping features, it is about building resilient Full-Stack Next.js and Node.js systems with strong maintainability, tenant isolation, compliance controls, and cost-aware infrastructure. I build for regulated environments requiring HIPAA, SOC2, PCI-DSS, OAuth2, RBAC/ABAC, and audit logs.
