About

I’m Muhammad Indrawan, a Senior Backend & Cloud Engineer (Top Rated Plus on Upwork, $100K+ earned across long engagements). I work mostly on Google Cloud, and I own the whole stack: infrastructure, backend services, and the LLM features on top of them.

I usually get called in when:

• Cloud costs are climbing and nobody can explain the line items
• Infrastructure was set up by hand and nobody dares change it
• A backend is buckling under load, or latency crept past what users tolerate
• An LLM feature works in a demo but is too slow, too expensive, or too unreliable for production
• Terraform exists, but it’s half-finished, drifted, or unmaintained
• Event-driven or IoT/MQTT throughput needs to scale past the current design

This blog is where I write up the technical side of that work: GCP architecture, Terraform and DevOps, Node.js/Go backends, event-driven systems, and production AI/LLM engineering, with real numbers, not vibes.
