Engagement models
Use the contract shape that matches the problem.
No staff leasing or full-time placement. The work is scoped around deliverables, cadence, and technical ownership.
Technical audit
Fixed-scope review, usually 2-3 weeks, with written findings and a remediation plan.
Project delivery
A defined build such as a module, integration, upgrade, or performance remediation.
Retainer
Monthly support for live commerce platforms: patches, small features, release support, and response times.
Advisory
Architecture review, code review, roadmap planning, and Magento guidance for existing teams.
The company
A founder-led software company, small on purpose.
Jotunn d.o.o. is a Croatian limited company built around Magento and Adobe Commerce engineering for agencies, merchants, and platform teams across Europe and North America.
The practice stays deliberately small, so senior technical ownership remains close to the work: discovery, delivery, change management, and follow-up support.
Work
Real work, documented plainly.

Read the full case study Price index failure in a 125M-row Adobe Commerce table
A national B2B distributor's production site started returning HTTP 429 errors. New Relic showed lock-wait timeouts, and the price index table was larger than the entire InnoDB buffer pool. This case study covers the diagnosis, the immediate pressure reduction, and the structural fix that was scoped next.
