πŸ‘‹ Hi, I'm Jay

Senior Software Engineer β€” Agentic AI & LLM Systems Β· Real-Time Data Β· Quant Tooling

7+ years building production systems: multi-agent AI platforms in live client use, a patent application in preparation on privacy-preserving multi-agent communication, real-time data platforms at petabyte scale, and event-driven AWS microservices handling millions of concurrent requests. Currently at Optum UK (EMIS Health) β€” Kafka streaming, Trino federated SQL, and Airflow orchestration over petabyte-scale healthcare data. Previously 3 years at JBA Risk (world-leading flood-risk modelling).


πŸ€– Agentic AI & LLM Systems

  • Custom Multi-Agent Orchestration SDK (private β€” details on request) β€” ~65k LOC Python/Pydantic, zero LangChain/CrewAI dependency: async event-driven runtime, RL adaptive orchestrator, MCTS planner, resilient provider layer (circuit breakers, fallback, hedging), in-loop guardrails with trust-tiered PII redaction
  • Mantrix (Cloudmantra) β€” production agentic data-intelligence platform in live client use: Temporal-orchestrated workflows on AWS, NLβ†’SQL analytics across PostgreSQL/BigQuery/Neo4j, hybrid vector + knowledge-graph retrieval
  • Enterprise GraphRAG β€” Neo4j + Pinecone hybrid retrieval over millions of medical documents
  • Patent application in preparation β€” privacy-preserving communication in distributed multi-agent LLM systems

πŸ“ˆ Quant & Trading Systems

  • quotient β€” C++ limit-order-book engine and market-making simulator
  • rust-orderbook-feed β€” live crypto order-book WebSocket client in Rust: Binance, Coinbase & Kraken depth feeds, correct book reconstruction from snapshot + incremental deltas, sequencing & checksum validation
  • Statistical Arbitrage Trading Bot (private β€” ongoing) β€” cointegration-based pairs trading with Kalman-filter dynamic hedge ratios, HMM regime detection, Random Forest signal filtering; Kelly-criterion sizing, MAE-optimized stops; Interactive Brokers integration
  • montecarlo_rust β€” Monte Carlo simulation experiments in Rust
  • Quant methods: NumPy, Pandas, SciPy, Statsmodels β€’ cointegration, mean reversion, Kalman filtering, regime detection β€’ Kelly criterion, volatility scaling, drawdown controls
