## About

Backend engineer with 6\+ years building scalable, reliable distributed systems\. At Dentira, I'm an SDE\-3 leading a six\-person vendor engineering team on a procurement platform serving large dental service organizations \(DSOs\), where correctness and performance at high volume are the whole game\. My day\-to\-day lives in event\-driven data infrastructure: MongoDB Change Streams, Kafka, and stream processing for near\-real\-time pipelines; Temporal for durable orchestration of long\-running workflows; and OpenSearch for search and observability — all on AWS/EKS across multiple regions, with data locality as a hard constraint rather than an afterthought\. On the performance side, I lean heavily on Redis — distributed locking, cache\-aware design, and the invalidation strategies that keep cached data correct under concurrency\. What I've built: • Order processing pipeline on Kafka, powering high\-volume order flows through the platform • Near\-real\-time data integrity monitoring across order systems handling millions of mutations a day • Proactive alerting and observability across the stack — infrastructure \(AWS, Kubernetes, resource exhaustion\), databases, and custom application\-logic alerts that catch issues before they page\. What I'm building now: • Order lifecycle automation on Temporal — end\-to\-end orchestration of the order journey with automated handling of exceptions and failures • AI agents that autonomously debug mission\-critical issues — structured decision graphs over MCP\-connected tools \(database, logs, code\) to localize failures fast\. I like systems that are observable, recoverable, and boring in production\. Always happy to talk backend, distributed systems, and data infrastructure — let's connect\.
