Services & Capabilities
I deliver full-cycle software services tailored to enterprise needs. Typical engagements include architecture and technical leadership, custom development, integrations, and long-term maintenance.
Integrations & Extensions
Extend existing systems or integrate third-party services with robust, well-tested connectors.
Full-stack Delivery & Ops
End-to-end delivery: design (Figma), development, deployment, server maintenance and monitoring.
Consulting & Tech Leadership
From architectural direction to team leadership — I help shape how software teams deliver robust systems.
Approach & Background
I combine technical depth with pragmatic product thinking. As a technical lead at a leading Croatian software vendor I have led projects, designed UIs in Figma and worked hands-on across backend, database and deployment. I prefer to solve domain problems, not chase the latest shiny stack — I can work with the tools that best fit your needs.
Real-world business software experience
Years of building and extending solutions for complex business domains.
Product-minded engineering
From ideas and wireframes to production-ready systems and monitoring.
Ops & server maintenance
Linux server management, deployment pipelines and long-term maintenance experience.
Personal projects: embedded systems and hobby game engine work (C/C++). Academic thesis on vector control on multicore ARM processors.
