Message

At Sourcelab Ltd., I design and implement fintech and compliance solutions with .NET, NestJS, TypeScript, React, and PostgreSQL. I also build cloud-native services and REST APIs that integrate identity verification, OAuth 2.0/OIDC, and compliance screening.

At VSG Bulgaria, I led the modernization of LoanVantage's spreadsheet-style financial analysis interface from Angular/jQuery to React while preserving its business calculations and workflows. Earlier, at Kukui Corporation, I led a five-engineer team modernizing MudTrax/Mudlick and designed a streaming approach that cut average client data ingestion time from about 42 hours to 2–3 hours.
