Hi, I'm M. Arslan

Full Stack Developer · Backend · DevOps · AI

I build full products end to end — modern web apps with React and Next.js, scalable APIs with Node.js and NestJS, backed by PostgreSQL, MongoDB, and Redis. I containerize with Docker, deploy on Kubernetes, run CI/CD and monitoring, and build AI agents that run in production. 3+ years shipping real systems for clients across Pakistan, the UAE, Europe, and the US.

Full products that are fast, observable, and built to last

From React and Next.js frontends to APIs, databases, Docker, Kubernetes, CI/CD, and AI agents — I build and run the whole thing.

// About

Full products, built to last
frontend · backend · DevOps · AI

I am a Full Stack Developer with 3+ years of hands-on experience building production systems end to end for real clients. On the frontend I build modern, responsive web apps with React, Next.js, TypeScript, and Tailwind CSS. On the backend I design and ship scalable REST APIs and microservices with Node.js, NestJS, and Express, backed by PostgreSQL, MongoDB, and Redis. I also handle the infrastructure — containerizing with Docker, deploying on Kubernetes and DigitalOcean, running CI/CD pipelines, and setting up monitoring with Prometheus and Grafana so systems stay reliable under real load. On top of that I build AI agent systems with OpenAI and Claude. My focus is clean, maintainable code and full products that are fast, observable, and built to last.

I own systems end to end — API design, databases, containers, deployment, and monitoring. No handoffs, no "that's not my job" when something breaks. My live SaaS is ChatPilot, a multi-tenant AI CRM used by paying clients in production.

I come from a strong competitive programming background — 700+ LeetCode problems and ICPC 2025 Regional — so problem solving, edge cases, and performance are second nature. I care about clean, observable systems that stay fast and reliable as they scale.

AI agents
wired into real
backend systems.

I build the AI layer that sits on top of solid backends — agents, LLM pipelines, custom MCP servers, and workflows that call real tools, take actions, and run reliably in production.

AI Agents

Chat, Voice & Call Agents

I build AI agents that plan steps, use tools, remember context, and fix errors on their own — chat, voice, and full call agents that talk to customers in real time.

  • Lead bots that talk to customers 24/7
  • Voice and call agents with OpenAI Realtime
  • Tool-calling agents that take real actions
  • Agents that read Slack and write reports
LLM Integration

OpenAI & Claude in Production

I integrate OpenAI and Claude into real backends — RAG over your data, function calling, and reliable prompt pipelines that run at scale, not just demos.

  • RAG over private data and docs
  • Function calling and structured outputs
  • Streaming responses and token control
  • Guardrails and fallback handling
MCP & Claude Code

Custom MCP Servers & Agentic Ops

I build agentic systems with Claude Code — custom MCP servers, Slack and GitHub integrations, and AI workflows that ship real code and run real operations.

  • Custom MCP servers for client tools
  • Claude Code agents for code review and ops
  • AI-driven CI/CD and deploy helpers
  • Internal tools that read context and act
Automation

n8n & Make Workflows

I build custom n8n and Make.com flows that connect AI agents to your business apps — easy for non-tech people to use and edit later.

  • Custom n8n nodes for any API
  • AI nodes for OpenAI and Claude
  • Self-hosted n8n on Docker
  • Make.com scenarios with branching logic

ChatPilot

Multi-tenant AI CRM Platform

A full multi-tenant AI CRM platform built on business messaging. It pairs a NestJS backend, a dedicated messaging server, a real-time web dashboard, and an AI agent layer so many businesses run on one system with full data isolation. AI agents chat with customers 24/7 and staff can take over any conversation at any time.
