Product leadership,
platform architecture,
production code

I'm Ricky Santosa — PM, architect, and builder based in Jakarta. Outside my primary PMO and delivery roles I've independently designed, built, and shipped 17 production-grade platforms spanning enterprise SaaS (marketplaces, AIOps, fraud detection, cybersecurity, data governance, PM/PMO intelligence), Indonesia-focused retail & commerce systems, and mobility infrastructure (EV charging). Rust preferred, pragmatic always.

Every number in this portfolio was extracted from the source repositories — no marketing extrapolation. strict clippy · argon2id · hash-chained audit.

Practice

Product Manager and hands-on full-stack engineer based in Jakarta, operating simultaneously as PM, architect, and builder. Strong background translating operational and governance complexity into scalable, auditable systems.

Primary stack is Rust (Axum / Tokio / SQLx) for distributed microservices, complemented by Laravel/PHP monoliths for cost-appropriate SMB and retail deployments. Every platform is Indonesia-first, operator-owned, auditor-ready on day one.
