Enterprise Next.js for Maersk Training.
The clearest proof of the audit-and-fix track: brought in directly by a global maritime-training company after an earlier build fell short, to audit it, rebuild it, and ship two production platforms.
Maersk Training
Called in directly to rescue a stalled enterprise build
Two production platforms for a global maritime-training enterprise — audited, rebuilt, and shipped directly for Maersk Training after the original delivery fell short of what the business needed.
- Engaged directly by Maersk Training after an earlier build didn't hold up — audited the codebase, rebuilt what didn't work, and shipped.
- Reporting and analytics dashboard — Recharts visualisations, Excel export, and NextAuth-secured access.
- Course-catalogue and e-learning platform on Contentful with GraphQL codegen and Algolia search, rebuilt to multi-locale enterprise standards.

“It is extremely satisfying to be able to give Nicklas a scope and simply redirect my focus elsewhere, because I know Nicklas is capable of remaining critical of both Delivery-Quality, and Value-Sanity. Nicklas will take any request and turn it into a functional product.”

Inherited build
A delivery that didn't hold up against what the business actually needed. We were brought in directly, after the fact.

Audit
Read the codebase end to end and wrote down what was broken, what was salvageable, and what each option would cost.

Rebuilt, not patched
Replaced what didn't work with typed, tested, multi-locale enterprise foundations instead of layering fixes on top of them.

What we run ourselves.
A studio that only ships other people's software never feels its own delivery model. Everything below is ours — built on the same guardrails, routing and review gates we sell, and where the model gets stress-tested before a client ever sees it.
