Designed the question bank management system, the assessment and questionnaire builder, the Crew Evaluation Test (CES), the proctoring and exam authentication feature, course reporting, and the student-facing test interface — across both admin and learner experiences.

Design the full platform across both the admin and student sides — question bank management, exam builder, the Crew Evaluation Test (CES), a proctoring system, course reporting, and the student test interface.
The question bank wasn't just a list of questions. Each one had a type, a language version, a difficulty weight, a lifecycle state, and links to specific competence requirements. The exam builder needed to support both simple tests and complex ones where questions were assigned based on a crew member's job role, ship type, and department. The proctoring feature added another layer — verifying that the right person was actually sitting the exam, using either a supervisor or a webcam.
Before designing anything, we mapped every state and rule in the question bank and exam workflows. A question moving from draft to published to deactivated follows specific rules at each step. For proctoring, we mapped the supervisor flow and the webcam flow side by side to understand where they differed before touching the design.

The question bank was designed with clear visual states so admins could see at a glance what was draft, published, or deactivated. The exam builder was structured around three drawing modes — draw all questions, draw randomly from groups, or draw by specific group combinations — with a preview so admins could check which questions would come up before publishing. The CES builder let admins set up question groups by vessel type, department, and operation without it becoming overwhelming. The proctoring flow covered supervisor registration, student authentication, and an admin review queue for flagged sessions. The student test screen was kept clean and calm — progress strip at the top, timer visible, save and come back later.



Training compliance in maritime isn't optional — it has real safety and regulatory implications. The proctoring feature in particular required careful thinking about trust and identity verification. The result is a platform that handles the full complexity of crew training management at scale.













A platform where admins can build multi-language assessments, set up job-role-based crew evaluations, run proctored exams, and generate course reports — all in one consistent interface. The student test experience was designed to be calm and clear, even under time pressure.
Mintra Training Portal combined complex workflows like question management, assessment building, proctoring, reporting, and role-based crew evaluations. Success depended on structuring intricate rules and regulatory requirements into clear, scalable workflows that administrators could confidently manage while keeping the learner experience simple and focused.

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.
