Your product doesn't need another developer who bolted an OpenAI call onto a to-do app. I've shipped React/Next.js/Node.js systems handling 25M+ monthly users, and I build AI into that same level of infrastructure, not next to it.
5+ years building production web applications, including a mobile editor used by 25M+ users a month, a real-time bidding platform handling thousands of simultaneous global users, and a generative AI platform live for 10,000+ users.
**๐๐ก๐๐ญ ๐ ๐๐ฎ๐ข๐ฅ๐:**
๐ป **Frontend:** React, Next.js, fast, SEO-friendly, production-ready interfaces
โ๏ธ **Backend:** Node.js, NestJS, Python, REST APIs, real-time systems, database design
๐ค **AI layer:** OpenAI, Anthropic, Gemini API integration, multi-agent systems, RAG pipelines, and AI automation that plugs into real business workflows
**๐๐๐๐๐ง๐ญ ๐ฐ๐จ๐ซ๐ค:**
โข PosterMyWall: React/Redux mobile editor used by 25M+ users/month, plus a Stripe-based checkout/download flow (Puppeteer, Redis, AWS)
โข Invaluable dot com: Next.js migration, NestJS real-time bidding microservice handling thousands of concurrent global users with live state
โข Alson ai: Generative AI platform (NestJS, Next.js, OpenAI, AWS) live for 10,000+ users
I care about how a system fails, not just how it works in the demo. Clean code, sensible error handling, and documentation your next developer can actually read.
If you're looking for a React/Next.js/Node.js developer who can also handle the AI side properly, message me with what you're building. I'll give you an honest read on scope before we start.

Full-Stack & AI Developer, NestJS Developer, Node.js Expert, React.js Developer, Next.js Developer, LLM Integration Specialist, API Integration, Backend Developer, TypeScript, RAG, GraphQL, REST API Developer.
Hi, I'm Syed. I'm a Full-Stack and AI Developer with 8+ years building web and mobile apps that ship and scale. My core strength is backend work in NestJS and Node.js, paired with clean React, Next.js, and Angular front ends. I also build AI/LLM features and handle the messy integration work most projects need, including payments (Stripe, MyFatoorah), CRM and ERP systems (HubSpot, NetSuite), messaging (Twilio), and real-time data.
๐๐ง ๐ญ๐ก๐ ๐๐ ๐ฌ๐ข๐๐, I build things people actually use in production: chatbots, RAG pipelines, document analysis and data extraction, and structured JSON output from LLMs. I've also set up self-hosted, on-premises models with Ollama for clients who need their data to stay private.
Over the years, I've worked with startups and established companies across fintech, e-commerce, healthcare, ride and transport services, and management platforms. I've delivered solo and as part of senior engineering teams, and I'm comfortable working to tight deadlines without letting code quality slip.

I ask good questions early, keep you in the loop, and own the problem instead of just the ticket. You get clean, documented code you can build on, and someone who stays calm when deadlines get tight.
