• High-Throughput Microservices: Technical Owner for the Java-based event-driven backbone serving 460M+ users; optimized Kafka and Kinesis consumers handling 1M+ RPS with sub-200ms latency across a distributed architecture.

• GenAI & RAG Orchestration: Architected a State-Aware RAG pipeline using LangChain4j and Pinecone; engineered an ingestion flywheel that embeds technical manuals into a Vector DB and synthesized them with real-time device state via a Kinesis-to-Kafka pipeline.

• Cost & Performance Optimization: Implemented Semantic Caching in Redis to slash LLM token costs by 80% and automated troubleshooting for global users, reducing manual support volume by 70%.

• Global Service Orchestration: Directed the technical delivery for Amazon Dash Replenishment (DRS) and Cloud-to-Cloud Voice integrations; synchronized technical release cycles and API contracts between US-based cloud infrastructure and Korea-based engineering labs.

• Operational Excellence & Resilience: Reduced MTTR by 35% by architecting fault-tolerant microservices using Resilience4j (Circuit Breakers, Bulkheads); standardized distributed tracing to isolate Kinesis shard-lag in real-time.

• Technical Leadership & Mentorship: Directed cross-functional execution for major product launches; mentored 5+ mid-level engineers on microservices best practices and standardized a "Design Doc" culture that reduced architectural rework by 25%.

• Founding Team Lead: Built the backend for a B2B Health platform (featured in WSJ) from the ground up; led a sprint team of 4 to implement secure security frameworks and prepared technical documentation for audits.

• Forward Deployed Engineering: Acted as the lead technical point of contact for clinical partners; managed on-site deployments and translated real-world requirements into backend architecture.

• High-Scale Batch Processing: Built a Spark-on-EMR pipeline utilizing Spark-SQL; reduced processing of biometric telemetry from 6 hours to 45 minutes while managing Hadoop-based snapshots for clinical data recovery.

• Cross-Functional Integration: Managed end-to-end data flows for real-time monitoring; handled cross-platform release cycles across firmware, mobile, and cloud teams.

Developing and designing disruptive digital health services using Hadoop,Hbase,java,Spark and Apache Phoenix.

• Worked with enterprise social network solutions production team (SAP JAM COMMUNITIES) on Web Development in an agile software development Environment.

• Developed End to end features (Backend plus Front End) in Single Page Web Application using MVC Framework and REST architecture. Got good experience of Ember JS, SCSS, JAVA, Rails, My SQL, Redis, Git and learned the best software WEB development practices.

• Developed the features and automated the test cases using Selenium (UNIT + REGRESSION) with continuous integration using Jenkins, and solved HIGH PRIORITY BUGS from JIRA to maintain high quality standards during weekly deployments to production.

• Worked independently to build out performance test suite using Master/Slave configuration in Jmeter for Social Collaboration Product. (Previously was a QA intern in same team).
