Senior🎓
Top SchoolJohan Idstam is a founder and pragmatic software engineer with 11+ years of professional experience designing secure, database-first systems and automating release management. He prefers tackling legacy complexity—SQL Server, T-SQL, business rules and CI-driven operations—over front-end polish, and favors minimal, elegant code to solve real problems. As founder of JSI Konsult och Bemanning and JSI Skattekonto he combines hands-on development, solution architecture and business analysis to deliver auditable, production-ready services. He has a strong security and DevOps mindset (OWASP, CI, application security) and a history of translating practical needs into robust architectures across finance and fulfillment domains. Outside commercial work he contributed Swedish localization to the popular Easy!Appointments project, reflecting a pragmatic approach to widening accessibility.
