Designed and implemented a real-time analytics monitoring platform using Apache Kafka, Node.js, and React to support both large millisecond-timestep simulations and continuous high-throughput data streams. Built Kafka producers and consumers to stream and process over 1M+ simulation messages per day, storing results in InfluxDB for advanced analytics and visualization. Led delivery of features across three products, coordinating with product owners and stakeholders. Enhanced system reliability by integrating Prometheus and Grafana dashboards, reducing downtime by 20% through proactive monitoring and alerting.

Collaborated with an Agile team to develop scalable iPaaS full-stack solutions using Java, JavaScript, and Spring, handling 10,000+ daily integration requests across enterprise systems. Integrated 6+ HR platforms via REST APIs for cross-platform data exchange. Improved reliability and maintainability by writing 30+ unit, integration, and performance tests in JUnit, increasing test coverage by about 20%.

Refactored and enhanced a React & ASP.NET website (V2), delivering bug fixes and new features. Restructured and optimized SQL databases with 100k+ records, improving query speed by 20% and reliability. Created a Python/Qt-based tool to boost productivity for multiple engineering teams.
