About this gig
AI agents are only useful when they can actually do something for your business.
I build custom AI agents that make decisions, work with your data, call your APIs, and act across your existing tools.
Examples:
- Lead qualification and prospecting
- Research and data-processing agents
- Document processing and decision workflows
- CRM and internal-tool automation
- Multi-step workflows with branching, retries, or human approval
- Custom integrations with APIs, databases, and internal systems
What you get:
- Custom AI agent built with Python + LangGraph
- Integration with your APIs, CRM, database, or internal tools
- Custom tool integrations, including MCP where appropriate
- Error handling, retries, and human-in-the-loop approval when needed
- Clean source code and documentation for future maintenance
Why work with me? I've run backend infrastructure for an e-commerce operation processing 236,000+ orders, and maintain an open-source framework for evaluating LLM agents.
Included: source code + setup docs. Not included: hosting and API/LLM costs.
Message me before ordering with your use case.
Available: 24/7
Best regards,
Mustafizur Rahman

I'm a developer with 7+ years of experience across WordPress/PHP web development and, more recently, custom AI agent systems built with Python and LangGraph. I've run production infrastructure for a high-volume e-commerce operation and delivered WordPress projects with a focus on reliability and long-term maintainability, not just launch-day polish. Whether it's a site that needs to run smoothly for years or an AI agent that needs to make real decisions in production, I build things meant to keep working after handoff.

FAQ
What kind of AI agents can you build?
Anything from a single-task agent (e.g., lead qualification) to a multi-agent system with tool access, memory, and approval steps. Message me your use case and I'll scope it.
Can you connect the agent to my API, CRM, or database?
Yes, this is the core of what I do, especially for systems without off-the-shelf connectors.
Can the agent take actions, not just generate text?
Yes. LangGraph agents can call APIs, write to databases, send messages, and make branching decisions based on real data.
Can you deploy it to my server or cloud?
Yes.
Do I get the source code?
Yes, full ownership, no restrictions.
Why LangGraph instead of a basic chatbot or no-code automation tool?
No-code tools are great for simple tool-to-tool workflows. LangGraph is worth the extra cost when the workflow needs actual decision-making, branching logic, retries, or combining multiple model calls with custom business rules.
