About

I am a Software Engineer 2 at Microsoft, working within the Azure Data Factory team to build high-scale data orchestration engines for Microsoft Fabric. With nearly 5 years of experience across industry leaders like Salesforce, Tekion, and Progress Software, I specialize in designing and scaling distributed backend systems using Java, Golang, and Cloud-native architectures. Career Highlights: At Microsoft: Currently focusing on high-throughput microservices and service orchestration for global data integration. At Salesforce: Redesigned a Business Rule Engine architecture, scaling it from 80M to 500M monthly hits while improving fault tolerance. At Tekion Corp: Built a scalable Kafka-based messaging system from scratch and launched the Travel Scheduler project. At Progress Software: Engineered a modern testing framework for ODBC/JDBC drivers, replacing legacy systems and streamlining data connectivity. I thrive on solving complex scalability challenges, optimizing low-latency APIs, and implementing robust design patterns to build reliable, enterprise-grade software.
