Muhammad Okfriansyah

Engineering Manager · AI Systems Architect

Jakarta, Indonesia — open to US remote

Engineering leader with 13 years of software engineering experience, including 6+ years leading high-performing fintech and SaaS teams. I ship payment infrastructure at scale — payment gateways, banking APIs (SNAP), and KYC systems — and apply that reliability discipline to autonomous AI systems: deterministic pipelines, orchestrators, and production workflows that don't break when left unattended.

Principles

Engineering constraints I enforce

01

Deterministic over probabilistic

Given the same input, produce the same output. Pipelines must be reproducible.

02

Idempotent operations

Every worker, stage, and retry produces the same result without compounding side effects.

03

Database-backed state

The database is the single source of truth. No in-memory-only state for what matters.

04

Orchestrator over agent chaos

A central coordinator owns execution flow. Workers stay stateless and replaceable.
