Mintra’s Training Portal is an online learning and assessment platform used by shipping and energy companies to manage crew training — from basic safety courses through to formal exams with real regulatory consequences. Crew members who don’t pass required certifications can’t sail. The platform has to be reliable, clear, and built around the real complexity of how maritime training works.
We redesigned the full system and designed several new features from scratch.

The question bank alone had enough complexity to justify a dedicated mapping phase before any design work started. Questions aren’t just content — each has a type, a language version, a difficulty weighting, a lifecycle state (draft, published, deactivated, archived), and links to specific competence requirements. Moving a question between states follows rules. Reinstating a deactivated question has its own flow. Breaking any of this creates problems downstream in exams and reporting.
We mapped every state, every rule, and every transition before drawing a single screen. By mapping every system before designing it, we avoided the retrofitting that happens when edge cases surface during testing.
We redesigned the question bank with clear visual states so administrators could see at a glance what was draft, published, deactivated, or flagged for review — without opening each record individually. Filtering, sorting, and searching were redesigned to work across libraries of hundreds or thousands of questions spanning multiple languages and subject areas. Bulk actions (publishing a set of questions, archiving outdated content) were given clear confirmation flows to reduce the risk of accidental changes at scale.
Exams on the Training Portal are configurable assessments with specific drawing rules determining which questions appear. We designed the exam builder around three drawing modes:
Admins can preview the question composition before publishing — seeing exactly which questions will appear (or the distribution logic if random) to verify the exam makes sense before it goes live.
The CES evaluates crew members against their specific role requirements. Unlike a standard exam, a CES is configured based on vessel type, crew member department, and operational role — so a chief engineer on a tanker gets a different question set than a deckhand on a ferry. We designed the CES builder so admins could configure these combinations without the complexity overwhelming the screen.

For high-stakes certifications, maritime training requires verified, supervised exams. We designed two proctoring modes:
The design challenge: proctoring creates friction by design. The identity verification steps need to be thorough enough to be meaningful, but clear enough that they don’t delay a candidate who is ready to sit. We mapped the supervisor flow and the webcam flow in parallel to keep the overall experience consistent while the verification methods diverged.


The learner-facing test screen was designed with one priority: nothing should distract from the exam itself. Clear progress strip across the top. Timer visible but not anxiety-inducing. Save-and-return functionality for longer exams. Navigation between questions without losing work. Works across device types, since crew members may sit exams on shared terminals with varying screen sizes.
The reporting module gives administrators visibility into how courses and assessments are performing — not just individual results, but aggregate data that supports both operational and commercial decisions:
Maritime training compliance has real consequences — for crew members who need their certifications, for companies that need compliant rosters, and for regulators who audit both. A poorly designed question bank leads to bad data. A proctoring flow with ambiguity leads to disputed results. The result is a platform that handles the full complexity of crew training management in one consistent interface.













Projects
We designed the full system from scratch — a campaign dashboard, template library, and a linear builder with side panel editing.
Six months across the full product — admin dashboard, adaptive testing, a KTU research experiment, and a broader UX restructure.
We redesigned the platform twice across four user types and built the design system from scratch as their only embedded designers.

I had the pleasure of working with Gytis for a long time, and he has consistently been one of the most thoughtful and dependable product designers I’ve worked with.
Gytis thinks deeply about the product, the user, and the business context behind every design decision. He is very strong at turning ambiguous ideas into clear, polished, usable experiences, and he brings a high level of taste and discipline to the work.
