Senior Software Engineer · Enterprise Systems Architect

I design and ship enterprise business systems and SaaS products across telecommunications, county government, agriculture, logistics, and automotive — from requirements and database architecture through deployment, migration, and training.

Building systems teams can trust month after month

Senior software engineer and consultant with over four years of experience architecting, building, and deploying enterprise business systems and SaaS products. Strong across the Python, JavaScript, and Java ecosystems with deep database expertise in MariaDB, MySQL, and PostgreSQL, plus hands-on delivery in the .NET and Microsoft Dynamics 365 Business Central stack.

I own the full delivery lifecycle — requirements engineering, database architecture, deployment, data migration, and end-user training — and lead cross-functional Agile teams that turn complex public and corporate requirements into scalable, automated systems.
