About

I'm a Senior Data Engineer and Cloud Data Consultant with 20+ years of experience modernizing analytics ecosystems with Snowflake, Microsoft Fabric, Azure SQL, and SQL Server. I build automated, scalable pipelines and resilient data models that turn raw data into reliable, actionable insight — especially in high-volume, mission-critical environments where performance, cost efficiency, and long-term maintainability are survival. My toolkit is deep SQL + Python, paired with AI-assisted development (GitHub Copilot, ChatGPT, Claude) to deliver solutions that are cloud-native, operationally practical, and designed to evolve beyond prototypes.

"To live in peace, free from rigid structures — building projects that flow naturally through intelligence and awareness. Technology should serve life, not the other way around."

Featured Projects

Crypto Arbitrage Scanner

FinTech

Scans 9 exchanges (Binance, Bitget, Bybit, Coinbase, OKX, KuCoin, Kraken, Gate.io, MEXC) for price inefficiencies. Uses Bellman-Ford shortest-path algorithm and triangular arbitrage detection. Includes a Swapper module for executing trades, WebSocket L2 order-book feeds, SDK bootstrapping for native exchange integrations, and a real-time balance monitor.

  • 4,000+ LOC scanner with graph-based arbitrage detection
  • 9 exchange integrations with 4 balance provider backends
  • Live swap executor with dry-run and production modes

OAI Code Evaluator

AI / ML

YAML-driven evaluation pipeline with rule-based scoring across Instructions, Accuracy, Optimality, Presentation, and Freshness dimensions. Supports regex/substring matching, threshold conditions, ranking normalization, rewrite post-processing, and structured audit metadata output.

  • 6-stage evaluation pipeline (adjust → rules → rank → rewrite → validate → summary)
  • Declarative YAML rules with regex, substring, and threshold conditions
  • 5-dimension scoring with configurable ideals and tolerances

Email Collector & Classifier

Automation

Multi-account IMAP collector supporting Gmail, Hotmail (MSAL OAuth device-flow), and Exchange. Classifies emails into Scam/Suspicious/Spam/Clean/Unknown using a weighted scoring engine with 200+ domain rules, URL-shortener detection, phone-pattern matching, and fuzzy deduplication.

  • 5-label classifier with weighted scoring and hard rules
  • 200+ domain classification rules
  • OAuth device-flow for Hotmail/Outlook
