At The Software Practice, I build and evolve a distributed construction payment platform spanning invoice APIs, manual billing, notifications, and Workday and DBS Bank integrations that support thousands of daily transactions.

I design reliable event-driven systems with AWS SQS and SNS, achieving over 99.9% message delivery success, and improve critical payment-service availability through root-cause analysis and production issue resolution. I also built Playwright regression automation with sharding and CI integration, cutting test execution time by about 60%.

Previously at Samsung R&D Institute Indonesia, I engineered cloud-based backend services and a streaming platform processing roughly one million events per second across channels. Using C#, Java, gRPC, Proto.Actor, Redis, FoundationDB, Kafka, Temporal, Docker, Kubernetes, and Helm, I helped double throughput and reduce deployment time by about 70%.

My work also includes high-concurrency APIs and ERP systems at Pasifik Satelit Nusantara, an automated valuation model for PT PLN, and full-stack projects across Django, React, TypeScript, Laravel, and .NET. I enjoy building maintainable systems that make complex workflows faster, more reliable, and easier to operate.
