At Onsite Electro Services, I reduced search latency from 5 seconds to under 200ms across APIs serving 700K+ searchable records and built a payment orchestration system processing 4,000+ payments through asynchronous workflows.

I've also built an LLM-powered document intelligence platform that automates 70%+ of support queries, asynchronous reporting pipelines, inventory workflows, and synchronization services that improved cross-system consistency by 95%. My work spans Java, Spring Boot, Kafka, Redis, Elasticsearch, AWS, and GenAI tools, including semantic search and RAG systems.
