Software engineer at Coredump / Hylastix who architected Janus across backend, embedded, mobile, and web tiers.

At Coredump / Hylastix, I led the Janus platform from inception through first-MVP staging delivery, making architectural decisions with a team that grew from two to five engineers. I bootstrapped its backend, web frontend, and Android mobile tiers.

I architected six independently deployable bounded contexts and a four-tier system spanning Spring Boot services, ARMv7 embedded controllers, an Android NFC app, and an Angular admin portal. I implemented transactional domain events with PostgreSQL and the Outbox Pattern.

At BelaDuga / Artmie, I took full architectural responsibility for Warehouse Internal and contributed to its ongoing migration toward Spring Boot microservices. I also delivered Gsheets Matador end to end as its sole developer, syncing calculated CSV data to Google Sheets.

Earlier, I contributed across Java enterprise, financial, and web platforms at FIS, Prodyna, Bel-Dev / FactSet, Sluzbeni Glasnik, and Realaiz / EuroDynamics. At Sluzbeni Glasnik, I built LoRa, an internal user-management tool that remains in use.
