Work Experience

Software Engineer (Part-Time) – QA Engineering at Bloomberg L.P. Frankfurt

January 1, 2026 - Present

Built a multi-user FIX 4.4/4.2 dark-pool venue simulator with per-session state isolation; drove a hybrid architecture and a 7-goal, 13-milestone roadmap through stakeholder review. Created a deterministic scenario engine and 95 automated pytest cases across 12 reproducible order-flow scenarios, covering 100% of BIDS-scoped test cases with no live-venue dependency. Reduced full test-suite runtime from 60s to 18s (~70%) by adaptive first-byte/drain-window socket reads while preserving determinism and a 100% pass rate. Diagnosed and fixed a QuickFIX threading deadlock by dispatching outbound sends to daemon threads, keeping inbound callback non-blocking.

Software Engineering Intern at Bloomberg L.P. Frankfurt

July 1, 2025 - October 1, 2025

Accelerated a hot serialization path over 8x in a production rule engine for enterprise live market-data fanout by replacing per-tick sprintf(heap allocation + runtime format parsing) with C++17 std::to_chars into stack buffers, shifting the path from memory-bound to CPU-bound. Re-architected the type-conversion layer with C++20 Concepts and templates, eliminating a 1,000+ line mapping table and cutting edit sites to add a new data type by ~70%; shipped to production and validated against the existing regression suite with Google Benchmark.

Software Developer (Part-Time) at Digital David AG

February 1, 2023 - December 1, 2025

Led a 4-person team to build and launch an internal AI résumé-screening tool: integrated the OpenAI API with structured-output prompts (score, reasoning) for candidate-to-job matching, and built an evaluation workflow on recruiter-scored CVs, iterating prompts to 90% agreement with human A/B/C ratings and a recruiter-validated ~50% cut in initial screening time. Engineered an enterprise legal case-management platform in C#/.NET on Azure, pairing Azure OCR with LLM-based extraction to auto-populate form fields from uploaded documents, reducing manual data entry for a key client by ~60%.

Lead Contributor at DroneDeck

December 1, 2024 - February 1, 2025

DroneDeck — Drone Telemetry Dashboard: cut dashboard startup time by ~60% via a centralized data service and background-threaded polling; built an offline API simulator for 100% local testability (lead contributor; graded 1.0).
