You will get Middleware API from Undocumented Protocol/API
Project details
This service is useful when you need to integrate with a web app, mobile app, vendor portal, internal dashboard, legacy system, or non-documented protocol. I can inspect request flows, authentication behavior, payload formats, and session logic, then implement a working API wrapper or automation service around it.
The goal is to turn a difficult manual process into a maintainable backend system your team can use through a simple API.

About Muh
AI Automation Engineer | Custom LLM Systems in TS & Go | RAG, Workflow
Purwokerto, Indonesia - 10:31 am local time
What that means in practice: I handle the full backend layer behind AI products. LLM API integrations, RAG pipelines, structured outputs, workflow automation, middleware, session and auth flows, database integration. Built in TypeScript, Node.js, and Go.
Before focusing on AI, I spent years on backend APIs, automation, and integrations across fintech, banking, and payment systems. Past work includes KTB Automation API, banking middleware for Krungthai Bank, a Hyperledger Fabric mobile e-voting platform, and reverse engineering undocumented API flows across payment systems.
That background helps me build AI tools as real systems, not just prompt demos.
I prefer custom-coded solutions when a project needs reliability, control, or deeper backend logic. I can start the same day after receiving a PRD, brief, or clear requirements. Async-first and
available 11 AM to 11 PM GMT+7, covering the full EU working day and US East Coast mornings.
Send the project details and I'll tell you clearly whether I'm the right fit.
