• Established coding standards and enforced engineering quality through code reviews, technical mentoring, and knowledge sharing.
• Coordinated cross-team collaboration across product, infrastructure, and enterprise integration teams.
• Won internal “Best Project Development Quality” award (2024).

Platform Modernization & Architecture

• Leading enterprise modernization initiative to migrate SAP Commerce platform to Spring Boot–based microservices architecture.
• Designed core system architecture supporting multiple business domains and supervising 3 parallel rewrite projects.
• Defined service boundaries, architecture standards, and implementation guidelines.
• Designed secure Role-Based Access Control (RBAC) model for service authorization and resource protection.

Rule Engine Platform (Rules-as-a-Service)

• Designed dynamic rule engine using Drools enabling client-defined conditions and actions without code deployment.
• Built reusable rules platform decoupling business logic from application services.
