10+ years architecting ETRM systems across European Natural Gas, Power, and LNG desks. Proven expertise in Endur AVS, JVS, WASM SQL performance tuning, and REMIT compliance.
Executed 4/4 trading queries flawlessly. Zero syntax errors, optimal index utilization, and correct join logic on split daily delivery schedules.
Identified gas weekend double-counting, bank holiday curve fallbacks, and REMIT out-of-order queue rejections with production-ready solutions.
Evaluated by active ETRM engineering leads. Outstanding code structure, error handling, and deep Endur AVS architectural knowledge.
Detected that joining `trades_main` with `trade_schedules` multiplied weekend trade rows when daily delivery strips split. Solved by aggregating schedules prior to join.
Recognized that INNER JOIN on `curve_prices` drops holiday trades when non-business day prices are missing. Implemented LEFT JOIN with prior-day proxy price fallback.
Designed a transaction sequencing buffer to ensure lifecycle modifications (Action Type 'M') wait until initial trade capture ('N') is acknowledged by regulatory gateways.
