Hartree Partners · Risk & Pricing

Work across the firm's commodities Market-Risk (VaR) and risk-reporting platform, partnering with traders, risk and support across oil, gas, power and physical commodities.

• Built and maintain Position Service ETL components (Python/Airflow) consolidating EOD/intraday feeds from 8+ ETRMs into a unified position store feeding all downstream reporting.
• Contributed to the migration to a new historical-simulation VaR engine and the risk-controls layer on top (configurable configs, official/preliminary runs, risk overrides) that produces VaR for the daily risk reports.
• Help own production reliability of the morning risk jobs — root-causing and fixing pipeline failures end-to-end, backed by diagnostics and day-over-day reconciliation that gates the risk report.
• Contributed to an interactive position viewer where traders build and save views and aggregations across any dimension (commodity, market area, counterparty, book) at daily or monthly granularity, with Intraday / COB / historical modes.
• Contributed to the risk-operations console — view and email risk reports, re-run VaR intraday, apply pricing / Risk P&L overrides, edit risk-engine/report mappings. Report pages now load from pre-built tables instead of slow on-demand aggregation.

Centrica Plc · Front Office Development

Supported the power trading desk — built data-capture, standardisation and monitoring tooling for European energy markets.

• Built Python services to capture European energy-market transparency data — REMIT urgent market messages, transmission/grid capacity and outage data — from multiple providers and venues (EEX, EDF), using a decoupled producer–curator design.
• Developed a data-curation platform standardising heterogeneous vendor feeds into a single canonical view — one consistent source of fundamentals for the desk to trade on.
• Built compliance alerting for algo trading — tracked daily order-message volumes against venue messaging limits and alerted the desk as thresholds approached, so they could act before a breach.
• Migrated ~10 TB of time-series market data from PostgreSQL to ClickHouse with automated reconciliation, materially improving query performance and storage compression.
• Implemented data-staleness and quality monitoring — scheduled jobs that reconcile against source, detect gaps/stale feeds and alert the desk early. Built a Conda environment setup tool standardising Python environments across desks.
