What I'm looking for

After years of running my own consultancy, I'm looking for a long-term role in a strong engineering team.

At Mellon Development J.D.O.O., I develop Laravel SaaS platforms including WDR Cloud Platform, FitApp, Housespilot and Moji Računi. I work across backend architecture, APIs and product interfaces, and operate the production infrastructure for these applications.

For WDR Cloud Platform, I developed and maintain a multi-tenant platform for bike leasing and fleet management. I also handle its CI/CD, monitoring and production infrastructure, and prepared technical and security documentation that passed the client's enterprise security and privacy assessment.

I operate 15+ production servers and work on security, backups and disaster recovery as part of production engineering. After years of running my own consultancy, I'm looking for a long-term role in a strong engineering team, contributing to technical decisions, code review and mentoring.
