Professional Summary

01

Senior Analytics Engineer with 8+ years across data engineering and analytics, now building production agentic-AI systems for enterprise finance — MCP-based agents orchestrated with LangGraph, monitored with LangSmith, and kept honest by human-in-the-loop review.

The agents stand on eight years of less glamorous but essential work: large-scale distributed PySpark pipelines, anomaly detection, and applied machine learning. I care most about making enterprise data — structured or not — reliable and usable, whether the consumer is a dashboard, a model, or an agent.

Professional Experience

Senior Analytics Engineer

Intuit · Mountain View, CAAug 2025 — Present

Agentic AI for enterprise finance — built carefully, with humans in the loop.

  • Built and shipped an agentic reconciliation system: LangGraph handles stateful, multi-step orchestration; agents scan financial data for discrepancies and classify issues (business / data / timing) using historical JIRA context over MCP — an analyst reviews every recommendation before it goes anywhere.
  • Published reusable MCP agents through the internal developer portal, instrumented with LangSmith for tracing, cost/latency monitoring and evaluation — catching prompt and retrieval regressions before production.
  • Programmatically analyzed 600+ Qlik reports to map dependencies and redundancies, then consolidated them onto modernized data-lake tables — validated end-to-end against general-ledger source of truth.
  • Built Python validation frameworks and moved report codebases to Git — version-controlled queries, real code review, faster QA with less manual reconciliation.

Selected Work

04

Agentic AI Reconciliation System · Intuit

Livein production

Agents that scan enterprise financial data for discrepancies, classify the issue using historical JIRA context over MCP, and propose a resolution — with an analyst approving every step. LangGraph for orchestration, LangSmith for tracing and evaluation. Less false-alarm triage, faster incident resolution.

LangGraph · MCP · LangSmith · Python · Human-in-the-loop

Enterprise Report Consolidation · Intuit

600+reports analyzed

Programmatic analysis of a sprawling Qlik estate — extracting metadata and table-level dependencies, finding redundancies via SQL analysis, and consolidating everything onto modernized data-lake tables with end-to-end validation against the general ledger.

Python · SQL · Data-lake migration · Automated validation

Anomaly Detection Framework · Apple

90%precision

Statistical methods (Grubbs' test) applied to flag suspicious user activity at production scale — strengthening data security and pipeline reliability without drowning the team in false positives.
