Owned the design and development of scalable microservices for a high-load billing platform (Java 17/21, Spring Boot) - from architecture decisions to production operation. Contributed to SOC 2 compliance remediation, resolving audit findings related to logging practices and session handling to strengthen data security controls. Built and maintained CI/CD pipelines (GitLab, Jenkins) ensuring smooth delivery and zero-downtime deployments. Collaborated closely with cross-functional DevOps, QA, and product teams to deliver reliable, high-throughput billing services.

Developed and maintained reactive microservices to support billing and payment logic in a high-load enterprise environment. Improved invoice processing performance by 30% by refactoring synchronous operations into an event-driven, reactive architecture using asynchronous service calls. Ensured high reliability and code quality with 85%+ test coverage (unit and integration tests) and implemented performance and end-to-end testing strategies. Configured and maintained Prometheus/Grafana dashboards for monitoring billing microservices in production, enabling proactive detection of integration latency and throughput issues.

Developed and maintained backend features for customer center and customer shop, improving product discovery and account management experience for millions of e-commerce users. Established robust CI/CD pipelines in GitLab, increasing release consistency. Designed and documented RESTful APIs using Swagger/OpenAPI to ensure ease of integration across teams. Managed Kubernetes deployments using Helm charts, standardizing configuration and release management across microservices. Migrated legacy monolithic backend to domain-driven Spring Boot microservices, improving deployment speed and fault isolation across the platform.

Developed and maintained backend features for customer product catalog with Java 7/8 and ATG (Oracle Commerce). Integrated external and internal systems using SOAP-based web services. Collaborated in transitioning core backend logic to Spring Framework, preparing for microservice adoption.
