Hi, I’m Yusuf. I am a Lead Software Engineer with over 8 years of experience specializing in Java and Spring Framework architecture, enterprise e-commerce platforms, and distributed systems. Throughout my career, I’ve designed and delivered high-traffic platforms for the Astra Group, including seva.id, auto2000.co.id, and motorkux.id.

My engineering philosophy focuses heavily on system scalability, platform modernization, and long-term technical strategy. Here is a look at what I do:

• Platform Modernization & Architecture: I am currently leading a major enterprise initiative to migrate multiple legacy SAP Commerce monolith projects into a highly scalable Spring Boot microservices ecosystem. As part of this, I design core system architectures, including secure RBAC models and a dynamic "Rules-as-a-Service" engine using Drools that decouples business logic from application services.
• Performance Engineering: I build systems meant to scale. By implementing full-page caching (EHCache, Redis) and custom image proxies (which cut image payload sizes by up to 80%), my teams have successfully reduced page load times to sub-second levels and ensured our platforms can easily handle 3× traffic spikes without downtime.
• Enterprise Integration: Beyond application code, I bring strong expertise in infrastructure and data architecture, utilizing event-driven integrations (Kafka) to connect enterprise systems like SAP CDP, SAP Emarsys, and SAP S/4HANA.

As an engineering leader, I act as an internal technical consultant for other teams and manage teams of up to 12 engineers. I own the end-to-end delivery process, from initial analysis to production launch. I take pride in mentoring developers, enforcing engineering quality, and driving platform evolution—efforts that earned my team the internal "Best Project Development Quality" award in 2024.
