  1. SG Analytics

    Data Scientist

    Current

    Production pipeline (client-facing)

    In progress

    Agentic financial model builder

    • Building an AI agent that turns SEC EDGAR filings for public and private companies into a complete, client-ready financial model in the client's custom template: income statement, balance sheet and cash-flow statement, forecasts, a revenue build and a DCF valuation.
    Completed · maintained for daily delivery

    Company risk-monitoring pipeline

    • Architected and own an end-to-end, client-facing production AI pipeline tracking 200+ companies across 91 global locations: an ETL process that extracts, deduplicates and loads news data for classification and daily client delivery.
    • Cut per-request latency 97% (2 s → 50 ms) with prompt caching, and reduced inference cost 33% by productionizing a custom ML model I trained for multi-label classification across 55 risk categories (92% accuracy, 91% F1).
    • Diagnose and resolve client-facing pipeline issues (data gaps, misclassifications, delivery failures) with under 1-hour turnaround, keeping daily delivery accurate and client trust intact.

    Client demos (quick prototyping)

    • Engineered an Ontology RAG demo for a regulatory banking client, built on OKF (Open Knowledge Format) with LanceDB for vector storage. It enables structured multi-hop reasoning over unstructured documents, with 48% lower token cost and 40% faster retrieval than standard flat-vector retrieval.
    • Built a fraud-ring detection demo for financial transactions: an ML anomaly-detection model across 40+ transaction-level and behavioural parameters that identifies coordinated fraud beyond single-transaction anomalies.
  2. SG Analytics

    Data Science Intern

    • Designed an intelligent SWOT Analysis System using RAG and Amazon Bedrock, integrating SEC 10-K and annual reports with web data to produce factually accurate, auto-generated reports.
    • Developed a smart web crawler and data pipeline using Python, Scrapy, FastAPI and AWS S3, automating extraction of 500+ URLs/minute with 95% accuracy.
    • Automated an SFDR-compliant CIM system to extract ESG data and KPIs from unstructured corporate documents, generating structured Excel reports for financial analysis.
  3. Chegg

    Subject Matter Expert

    • Delivered 400+ optimized solutions in C++, Python, Data Structures, Algorithms, and Optimization.
    • Provided comprehensive explanations on a wide range of computer science topics with an Average rating of 4.5+.

It's easy to lie with statistics. It's hard to tell the truth without statistics.
