## About

```text
At a confidential energy trading client, I engineered a Kafka-based pipeline for automated data intake, processing, and real-time result delivery. I also optimized the what-if scenario engine, reducing processing time to approximately one-third of its original time.

At TSImagine, I improved RiskSmart’s event pipeline throughput by 267% and implemented a Margin Hierarchy framework for individual client portfolios. I also integrated ICE Risk Model 2 into the risk calculation pipeline.

Across fintech, travel, energy, and SaaS projects, I’ve developed Python backend systems, APIs, and integrations. At BCD TripTech, I integrated hotel booking providers and corporate virtual card payments, and contributed to an internal distributed tracing tool.
