Yusuf Adiputera Lead Software Engineer specialized in Java, Distributed Systems, and Enterprise Commerce

Lead architecture and evolution of enterprise-scale e-commerce platforms, driving modernization from monolithic SAP Commerce systems to a scalable microservices ecosystem across multiple business domains.

Architecture & Platform Ownership

• Designed and implemented the core platform layer for enterprise-scale commerce; co-defined service boundaries and integration contracts with the Solution Architect.
• Owned the shared core layer that core, CMS, and product services depend on.
• Established service boundaries, platform standards, and long-term system evolution strategy.
• Built reusable platform capabilities including rules engine and shared infrastructure components.

Platform Modernization

• Leading the enterprise-wide migration from SAP Commerce monolith to Spring Boot–based microservices.
• Technical authority for the core platform library consumed by 3 product teams across multiple business domains.
• Defined engineering standards and implementation guidelines for distributed systems.

Scalability & Performance Engineering

• Diagnosed 10× request amplification on SAP Commerce Accelerator via Datadog (20–30 inbound RPS to 200–300 internal ops/sec).
• Implemented EHCache full-page caching with selective invalidation, reducing internal operations by ~70-85% and P95 latency from 2.1s to ~800ms.
• Improved system resilience to handle 3× traffic spikes without downtime or horizontal scaling.
• Reduced image payload size by up to 80% through custom image proxy service.
• Optimized storefront performance via CMS lazy loading and rendering improvements.

Security & Access Control

• Designed JWT/OAuth2-based access control across microservices using a Permission-Based Access Control (PBAC) model, where API endpoints are secured by granular permissions via custom @Secured annotations rather than broad roles.
• Implemented a Redis-backed access-token cache with DB fallback for validity checks, and time-bounded role grants.

Enterprise Integration

• Contributed to SAP Customer Data Platform (SAP CDP) and SAP Emarsys implementation for unified customer data and marketing automation.

Engineering Leadership & Technical Influence

• Led a team of up to 12 engineers delivering end-to-end platform development.
• Acted as internal technical consultant across multiple teams, providing architectural guidance and solution design for parallel projects.
• Drove cross-team technical alignment, ensuring consistency in architecture, standards, and best practices.
• Mentored engineers and senior developers on system design, performance, and scalable architecture.
• Collaborated with product, infrastructure, and enterprise integration teams to align technical solutions with business goals.
• Owned CI/CD pipeline design and deployment strategy across Azure DevOps and Jenkins.
• Awarded Best Project Development Quality (2024).

Selected Achievements

• Delivered motorkux.id go-live (2022) and seva.id marketplace launch (2020) with payment, shipping, and 3rd-party integrations.
• Decision-as-a-Service. Designed a Decision-as-a-Service platform that lets business teams author and ship new pricing, promotion, and eligibility rules directly, without going through backend release cycles. The key design choice was keeping the engine intentionally generic: it doesn't know what a Customer or Product is, it just evaluates conditions on whatever data the client sends in. That's the invariant that lets new rules onboard without engineering work. Backend involvement is bounded to genuinely new categories of rule logic (such as adding a new type of condition), which is rare and easy to distinguish from "add a new rule."
• Led multiple SAP Commerce upgrades across enterprise platforms (seva.id, auto2000, motorkux.id - versions 6.6 → 2205).
• Developed custom promotion engine supporting location-based quota without coupon dependency.
