Surya Tresna Agung

Principal / Staff / Senior Backend Engineer Jakarta, Indonesia 10+ years, almost all as an IC

I'm seeking new challenges—building impactful projects or joining a team dedicated to making a difference.

Distributed systems, high-throughput and low-latency infrastructure. I turn monoliths into event-driven services that hold up under real load. Ten years hands-on as an individual contributor — I stay close to the code and the production incident.

AI is part of my daily practice, not a side experiment: agentic workflows, a central knowledge base (second brain), and MCP tools wired into how I ship.

01

Open for projects

Taking on backend and infrastructure work — architecture, rebuilds, and systems that need to survive production traffic.

Custom Business Software

Internal platforms, ERP and inventory engines, workflow systems.

Trading Systems

Order matching, market data feeds, FIX and WebSocket pipelines, low-latency execution paths.

Marketplace Platforms

Catalog, transaction and settlement systems built to scale.

Game Backends

Realtime state sync, matchmaking, and session infrastructure.

AI Systems

Build or upgrade your AI implementation — agentic workflows, central knowledge bases, and MCP tools.

Retrieval & Context Infra

Vector search, ingestion pipelines, and context plumbing that keeps agents grounded.

Production-grade only. Every system above has been built and run at scale in industries where downtime costs money — brokerage, ride-hailing, and national marketplaces.
