Summary
I'm a Lead Software Engineer with 8.5+ years of experience specializing in Java, Spring Framework architecture, and distributed systems. I've designed and delivered enterprise-scale platforms for Astra Group (PT Astra International Tbk, IDX:ASII, Indonesia's largest diversified conglomerate), including seva.id, motorkux.id, and auto2000.co.id, spanning full-headless architectures and platforms serving millions of monthly active users (MAU).
I'm currently leading an enterprise modernization initiative migrating SAP Commerce monoliths to a distributed Spring Boot architecture. For each platform, the backend is decoupled into distributed services structured around traffic patterns and authentication boundaries. To eliminate redundant development across teams, I architected a shared multi-module core commerce library that provides foundational commerce capabilities and domain models for product teams to extend and override.
As an engineering leader, I lead and upskill 12 engineers, act as an internal technical consultant across parallel projects, and establish the technical standards that drive long-term business growth.
Key Achievements
- Lead Engineer: Led engineering for motorkux.id and seva.id marketplace, delivering high-availability platforms serving 1.5M–2M+ monthly active users (MAU).
- Award Recipient: Received the internal "Best Project Development Quality" award (2024) for enforcing strict CI/CD quality gates: zero critical security vulnerabilities, passing SonarQube gates, 100% automated acceptance test reliability, and reliable delivery.
- Decision-as-a-Service: Designed a domain-agnostic Decision-as-a-Service platform powered by Apache Drools to evaluate eligibility rules across multiple applications without backend deployments.
- Performance: Diagnosed 10× request amplification on SAP Commerce Accelerator via Datadog; reduced P95 latency from 2.1s to ~800ms via EHCache full-page caching, enabling the monolithic storefront to absorb 3× traffic spikes (peaking at 60–70 page-request RPS) directly from cache without horizontal scaling.
- Image Optimization: Built a custom image proxy service, reducing image payload size by up to 80% and saving substantial bandwidth across high-traffic platforms (2024).
- Modernization: Leading the migration of SAP Commerce monoliths to distributed Spring Boot services separated by traffic patterns and authentication boundaries, while architecting a shared core commerce library adopted across 3 independent product teams.
- Enterprise Integration: Built event-driven Kafka integrations connecting SAP Commerce with SAP CDP and Emarsys for real-time customer profiling and marketing automation.
