The internal AI platform at MPM

Private systems, described in the open. Problem, outcome and stack for each.

01Agent platform

Agent Builder

  • LangChain
  • LangGraph
  • MCP
  • vLLM
  • LiteLLM
  • Next.js
  • TypeScript
Problem
Every team that wanted a chatbot rebuilt the same plumbing — prompting, tool wiring, auth and deployment — and none of it was reusable.
Outcome
One workspace where a team composes an agent from tools, MCP servers and functions, then publishes or embeds it without writing infrastructure.

02Retrieval service

RAG Knowledge Base

  • RAG
  • ChromaDB
  • Nomic Embed v2 MoE
  • LangChain
  • OCR
  • Python
Problem
Agents needed to answer from company documents, but the documents could not be sent to a hosted embedding API.
Outcome
Documents are embedded locally into ChromaDB collections and served to agents over an API, so grounding never leaves the network.
Full write-up
03Architecture documents

App Consultant

  • LangGraph
  • vLLM
  • LiteLLM
  • Next.js
  • TypeScript
Problem
Engineers and analysts wrote the same required documents in different formats, making architecture reviews harder.
Outcome
A guided conversation produces a PRD and architecture document following the internal templates.

04Decision support

Successor Planning

  • Python
  • AHP
  • TOPSIS
  • LangChain
  • vLLM
Problem
HR succession planning needs rankings that reviewers can reproduce and inspect.
Outcome
Computes rankings with AHP and TOPSIS; the LLM explains scenarios without changing the scores.

[02] About

Engineering, from backend to AI

Five years of backend and platform work, now pointed at applied AI.

I’m an AI engineer at MPM in Surabaya, building internal AI platforms and applications.

Previously, I spent four and a half years modernising backend systems. I’ve also built freelance web applications since 2020.

01

LLM infrastructure

Self-hosted model serving and a central gateway that fronts every internal application.

  • vLLM model serving
  • LiteLLM gateway
  • Ollama
  • Routing, auth & usage tracking
02

Agent development

LLM-backed applications and stateful, multi-step agent workflows over enterprise data.

  • LangChain
  • LangGraph
  • Internal agent builder
  • Data warehouse retrieval
03

Backend & platform

The microservices, containers and pipelines the rest of it runs on.

  • Node.js & .NET
  • Microservices architecture
  • Docker & CI/CD
  • PostgreSQL & SQL Server
