About

// who I am

Over the past 6+ years, I have led production AI/ML initiatives for Insurance, Petrochemicals, and Financial Services clients across the US, Australia, and the Middle East — translating ambiguous problems into measurable impact.

My recent focus is Generative AI, Agentic AI (LangGraph), and time-series forecasting. I have shipped a conversational claims agent operating at ~99% success across 22,000+ production queries, and a multi-agent fraud detection platform that cut claim adjudication from hours to under 2 minutes. Earlier engagements delivered >95% forecasting accuracy and ~35% process optimization for global clients.

Engineer by education, data whisperer by profession — a firm believer that numbers tell captivating stories. Outside of the data universe, I'm all about finding balance.

WEA Claim Analytics Agent
LangGraph · Python · Pandas · Flask · Plotly Dash
  • Conversational AI for Claims Analytics: Architected and deployed a production LangGraph agent on Cortex Lab that translates natural-language questions into executable code over 7M+ claim activity records from MIMICA in real time.
  • Multi-Stage Reasoning Pipeline: Intent triage (Conversational / Simple-Data / Multi-Step), dynamic plan decomposition, code generation, sandboxed execution, correctness verification, and a self-correction loop with up to 5 retries and persistent error memory.
  • Code Safety & Guardrails: 6-layer safety framework — prompt injection (instruction override, persona hijack, prompt extraction, delimiter, code injection, PII exfiltration), import blocking, timeouts, output caps, schema/answer caching, S3-persisted trace logs.
  • Production Deployment: Gunicorn + Flask + Plotly Dash with async polling-based streaming for real-time response delivery.
  • Outcome: ~99% success across 22,000+ production queries over 150 active days (100% in the most recent week).
ClaimIQ Analytics Accelerator — Multi-Agent Fraud Detection
LangGraph · FastAPI · React · Docker · WebSocket · Azure AI Foundry · Bedrock
  • Multi-Agent Architecture: LangGraph-orchestrated pipeline of 7 specialized agents for FNOL intake, loss-cause classification, and parallel fraud adjudication across structured, document, visual, and network-graph modalities.
  • Hybrid ML + LLM Reasoning: Pre-trained XGBoost classifier wired through a provider-agnostic LLM layer supporting Azure AI Foundry and Amazon Bedrock for flexible model switching.
  • Visual & Document Forensics: Image authenticity checks (reverse search, AI-generated detection) and cross-document discrepancy reasoning surface manipulated evidence and inconsistent claim narratives.
  • Network Graph Intelligence: Fraud-ring detection via entity overlap (garage, broker, customer, ZIP) visualized as an interactive graph for adjusters.
  • Smart Triage & PII: Auto-routing to Auto-Approve / Manual Review / SIU with audit-logged decisions; upstream PII masking via Microsoft Presidio for GDPR/HIPAA-aligned handling.
  • Outcome: Reduced claim adjudication from hours to under 2 minutes with explainable, evidence-backed verdicts adjusters can defend in SIU referrals.
Non-Catastrophic Claims Forecasting
Python · TensorFlow · Plotly · Chronos · TimesFM · TabPFN · PatchTST · NBEATS
  • Meta-Modeling Architecture: Multi-layer framework spanning 48 U.S. states and 7 lines of business, ensembling Chronos LLM, TabPFN Timeseries, TimesFM, PatchTST, NBEATS, and Ridge regression on residuals.
  • Accuracy & Stability: >95% average accuracy on a 56-month validation window with a rolling 26-week horizon at weekly granularity — consistent across market and seasonal regimes.
  • Outcome: Enabled state-level dynamic resource allocation and capacity planning across regions and lines of business.
Insurance Policy Evaluation Optimization
Python · SQL · Excel
  • Questionnaire Optimization: Analyzed 107 evaluation parameters using Cramér's V and Phi-coefficient association tests to identify redundant and interdependent variables.
  • Feature Prioritization: 2-way / 3-way ANOVA against claim outcomes (high SSR vs. SSE) retained categorical questions with high discriminative power.
  • Outcome: Cut to 60–70 items per state-specific compliance — ~35% faster policy evaluation, ~14% shorter underwriting lifecycle.

Intermittent Demand Forecasting via Meta-Modeling (S&OP)
Python · RapidMiner · Mar 2023 – Nov 2023
  • Cannibalization Detection: Identified product cannibalism and upgrade transitions using cointegration and distributional tests across the SKU portfolio.
  • Product Association: Discovered SKU interconnections and built alias mappings from historical purchase patterns via Market Basket Analysis.
  • Modeling: Meta-modeling solution combining Linear Dynamical Systems and Deep Auto-Regressive Recurrent Networks, scaled to ~2,600 SKUs across ~49 countries in the MEAF region.
  • Leadership: Led the data science squad, owned client comms, and drove the transition to Agile-Waterfall hybrid — improving utilization tracking, velocity estimation, and delivery quality.
Sales Price Prediction — Polyethylene Sub-products
Python · RapidMiner · SARIMAX
  • Multivariate Time Series: Deployed SARIMAX models tailored to each sub-product across global sales offices.
  • Outcome: ~97% accuracy across 22 sales offices globally for all 3 polyethylene sub-products.
Document Classification & Automation
Python · SQL · XGBoost · Plotly Dash
  • Performed EDA and pre-processing to build training data from thousands of customer emails.
  • Classified claims documents using XGBoost on text from emails, lodgment files, and audio transcripts.
  • Built a model-monitoring dashboard in Plotly Dash to track target and feature drift in production.
