At Edukasi Teknologi Finansial (Emtrade), I extended the RabbitMQ-based InsightSentry pipeline to process SIP market data across 11,000+ symbols. I also contributed to payment processing, login auditing, and data integrity flows.
At The KPI Institute, I designed and built an LMS backend from scratch using more than 10 microservices, and led a backend team of up to five engineers. I improved reporting performance from over 10 seconds to under one second through PostgreSQL indexing, query optimization, and code refactoring.
