Systems and quantitative engineer with 18+ years building production systems across financial reporting, data/BI automation, forecasting, and open-source infrastructure. At Kreston BulMar, I design and implement financial-data software for BG GAAP/IFRS reporting and validation: 69 mapping rules, 17 validation rules, and 53% test coverage across the full application (approximately 73K LOC + 38K LOC). Earlier, I built a 15,000+ line VBA forecasting system supporting weekly forecasts for more than 200,000 kg of products, and at DSK-Rodina reduced a three-hour data-cleaning workflow to one click. My current public work focuses on local-first AI infrastructure, Rust/PyO3 systems, and simulation-first autonomy.
Started 13 October 2025. I design and implement production financial-data software for BG GAAP/IFRS reporting and validation. Kreston BulMar is a member firm of Kreston Global.
Built data/BI automation, fraud-detection analytics, reporting, and operational workflows for a pension-insurance company.
Built and maintained the company's long-lived sales-forecasting and analytical infrastructure, used daily by executives throughout the thirteen-year role.
Worked across customer engagement, market positioning, sales strategy, and commercial analysis, building the business context that later informed my systems work.
