About

Backend engineer who built an agentic LLM system for private equity/finance that answers questions over enterprise contracts and documents using a vector-db RAG pipeline. Differentiator is a trust-focused citation framework (with highlighted source text) to reduce hallucinations in high-stakes workflows, plus strong DevOps experience deploying microservices on Kubernetes with Helm/GitOps and building Kafka real-time pipelines.

Key Strengths

• Designed and owned agentic LLM backend architecture for enterprise workflows
• Built robust RAG pipeline backed by a vector database to ground responses
• Implemented citation/traceability framework with source linking and highlighted evidence to reduce hallucinations and increase user trust
• Built CI/CD with GitHub Actions including automated tests, validation, performance testing, and image builds
• Deployed containerized microservices to Kubernetes with rolling updates, namespaces, and Helm-managed configs
• Built Kafka-based real-time pipeline handling burst traffic with partitioning and ensuring exactly-once processing via offsets and idempotent writes
• Planned phased infrastructure migrations with dependency mapping, risk analysis, and production-mirroring staging validation
• Built and deployed production LLM/RAG system for enterprise document/contract Q&A
• Designed transparency features (citations + highlighted source text) to drive trust and adoption in finance/high-stakes use cases
• Integrated structured and unstructured enterprise data via robust ETL for unified conversational querying
• Optimized RAG for low-latency, accurate, grounded responses (indexing/retrieval tuning + domain fine-tuning)
• Strong agent/workflow engineering using modular components, retries/fallbacks, and production monitoring
• Rigorous evaluation approach: edge-case testing, domain benchmarks, and LLM-as-judge scoring
