Experience
Senior Software Engineer & Founder
Oct 2017 — Present · US
Founded consulting practice specializing in complex system transformations for SMBs. Currently architecting RESTful and GraphQL APIs handling 100K+ requests/minute using Python and Go, with event-driven microservices leveraging message queuing and pub/sub patterns.**Key Achievement**: Led $70M federal unemployment platform modernization serving Vermont, Mississippi, and West Virginia. When 2M+ unemployed citizens couldn\'t access benefits due to failing 1980s COBOL/VBA systems, I evolved from testing specialist to technical lead, delivering functional web platform and saving $5M in taxpayer funds through automated testing framework replacement.**Legacy System Expertise**: Successfully modernized and decomposed 1990s VBA/VB/Java desktop applications into maintainable, modular architectures. Applied Oracle GoldenGate expertise to streamline complex data integrations while coordinating technical decisions across multiple state governments and educating non-technical stakeholders on modern development practices.**Current Focus**: Leading API design reviews and establishing backend engineering best practices for high-throughput distributed systems.
