AI Engineer.
I build production AI systems: RAG pipelines, MCP servers, and agentic workflows that actually ship. Right now that includes AI managing 1B+ IDR in enterprise contracts.
AI systems in production.
Six systems, all live. No demos, no prototypes. Real users, real uptime, real consequences.
MCP Integrations
MCP servers wiring LLMs into internal APIs, databases, and business logic. Agentic calls under 200ms.
Agentic Workflows
Multi-step agents with tools, memory, and planning loops. Human-in-the-loop where it matters.
SEO Agent
Audits websites and ships actionable SEO fixes for paying clients.
Financial Agent
Reads bank data, analyzes spending, writes reports. Not a chatbot wrapper.
Procurement AI
Procurement platform for ADW + BRI, managing 1B+ IDR in contracts.
Things I've written.
Short essays on AI systems, tool integrations, and production engineering.

What people say.
From the people who hired me, managed me, or shipped alongside me.
Asrafil restructured our delivery process and got a stalled banking project to production in two months. He is the engineer you hand the hard problem to.
He delivered our crypto payment integration end-to-end — clean architecture, clear communication, zero surprises at handover.
Top Rated on Upwork for a reason. Scoped honestly, shipped early, and the system still runs untouched a year later.
