I turn expensive, ambiguous data operations into dependable production systems: agents that shorten incident response, platforms that make governed data self-service, and automation that gives senior engineers their time back.

Today I am a Senior Software Engineer in Data & AI Platform Engineering at Red Hat. Across eight years, I have built for regulated enterprise platforms and consumer products serving up to 120M+ users and 500M events per day.

What I build

01 / Agentic AI

Production MCP and LangChain systems for investigation, release orchestration, metadata intelligence, and operational decision support—with observability and human handoffs designed in.

02 / Data platforms

Self-service data products on Snowflake, Databricks, dbt, Spark, and Delta Lake, with governance, quality, lineage, and cost controls embedded in the paved road.

03 / Platform engineering

Cloud-native control planes and developer workflows built with Python, Go, Kubernetes, OpenShift, GitOps, Terraform, and pragmatic automation.

Systems I have shipped

System	What changed	Scale and stack
Data Reliability Agent	Automated first-line pipeline triage and reduced initial investigation from ~38 minutes to ~4 minutes.	MCP, LangChain, OpenShift, Langfuse
Release Assistant	Orchestrated governed releases and saved 1,000+ lead-engineer hours annually.	Python, GitOps, Snowflake, 150+ compliant data products
Self-service Data Mesh	Replaced legacy Redshift/Starburst paths and reduced infrastructure cost by $200K+/year.	OpenShift, dbt, Snowflake, Kubernetes
Consumer AI at scale	Built GenAI search, recommendations, and conversational systems for Tata Neu and Beem.	120M+ users, 500M events/day, 12 Indic languages

Open source, upstream

I contribute correctness fixes, security hardening, CI improvements, typing support, tests, and documentation across the data and AI ecosystem.

64 merged upstream pull requests across 30 repositories, including the DuckDB, vLLM, dbt Labs, Red Hat, llm-d, Apache, and LangChain communities.
