Project details
Your product needs a strong and reliable backend. I am a nodejs developer who builds the core systems that make applications work. I create fast and secure apis, real time features, and scalable servers.
I focus on practical solutions. I build rest and graphql apis that are easy to use and maintain. I add real time capabilities like live chat and notifications. I work with databases like mongodb and postgresql to ensure data is managed well. I also connect third party services such as payment systems and cloud storage.
I deliver:
Custom NodeJS API Development: Lightning-fast RESTful APIs and GraphQL endpoints.
Real-Time Solutions: Interactive features like live dashboards and messaging
Third-Party Connections: Flawless integration with payment gateways, AWS S3, and email services.
I believes in clear communication and straightforward results. I write clean code and stick to deadlines. My approach is to understand what you need and deliver a backend that works.
If you are looking for a nodejs developer to help build your project, let's talk. I am ready to get started.

AI Coding Tools Expert & Coach Needed (Claude Code, Cursor, Open Claw)
Tanzeel really helped me become an AI-first executor. He was really the first person who made me familiar with terms like MCP, API, et cetera. When it comes to technical knowledge, he has a very deep expertise, so I would really recommend working with him.

Job Success
Lahore, Pakistan - 7:51 am local time
I specialize in AI Integrations, voice AI systems, RAG pipelines, and AI Agent development and 𝐎𝐩𝐞𝐧𝐂𝐥𝐚𝐰, for startups and businesses ready to automate the work that's slowing them down.
— WHAT I'VE SHIPPED IN PRODUCTION —
✅ Voice AI agent that replaced manual patient intake — zero staff needed for initial screening healthcare - (TopHealth AI),
✅ ML-core AI product — end-to-end, from model to production - (Akki.ai)
✅ End-to-end taxi booking platform live, scaled, real users - (TasleemTaxi),
✅ Published Jira Forge app on Atlassian Marketplace went through full review - (AgilePulse)
✅ Retail POS system deployed across UAE locations, handles real transactions daily - (Syspos)
— MY STACK —
📌 Voice AI: Vapi, ElevenLabs, Retell
📌 AI/ML: LangChain, LangGraph, RAG, OpenAI, OpenClaw, Anthropic/Claude Code
📌 Backend: FastAPI, Node.js, Python
📌 Automation: n8n, custom agentic orchestration and Twilio
📌 Frontend: Next.js, React
📌 Platforms: Jira Forge (Atlassian Marketplace)
📌AI Integration Architecture: connecting LLMs, Voice AI (Vapi/ElevenLabs), and automation.
Most of my work right now is AI voice agents. Healthcare, fintech calls, legal intake, real estate, customer support, I've built for all of them. One of my favorites was a Vapi AI receptionist for a clinic chain in Florida. Patients call, it answers, books the appointment, done. No staff needed at 2am. I also built an outbound voice agent for a taxi company in Oman that takes booking calls in plain natural language. These handle real calls from real customers every day, which is a very different thing from a demo that works once in a sandbox.

I’ve been working as AI Agent developer done 100s of AI Integrations for the last 5+ years, and I can confidently say I’ve done it all.

I also do a lot of agentic work with Claude API and MCP. If you don't know MCP (Model Context Protocol), it's basically how you give AI agents real tools and a shared brain instead of stuffing everything into one giant prompt. I've built custom MCP servers and set up orchestration where multiple agents pass work between each other and actually finish tasks on their own. Some of this runs through n8n or Make, some is pure code. Depends what the project needs.

I've strong experience with AI Integrations and building AI Agents using N8N, Vapi and other tools. Moreover, I've deep expertise in Anthropic Claude Implementations and Claude Integrations for multiple industries like healthcare, health-tech, Real estate, and financial sector.
Most AI agent developers will leave you in dark when something stuck, I'll stay with you until it's done, and I never leave you with something you can't own and scale.
