Bogdan "PET" Petrar

Part of the Health & Social Care division, designing clinical software deployed across 55+ NHS Mental Health Trusts. Spent time on-site in hospitals and ran hundreds of interviews with clinicians, administrators, and product teams to understand how these systems actually get used.

• MHA - An independent product within the RIO suite used by administrators to manage the legal process around patients detained under the Mental Health Act: sections, hearings, consent to treatment, patient rights, nearest relatives. My main project. I own it end-to-end: research, feature prioritization, design, and frontend implementation
• RIO - Electronic Patient Record, the 2nd most-used EPR in the UK
• Patient Flow Manager - Digital whiteboard for bed management
• InPatient Management - Management of wards and the patients on the wards
• RIO Configuration - Redesigning parts of the configuration system, including People Management (permissions & user management), clinics configuration, and other areas

Across all of these, my work covers research, information architecture, UI design, and building production frontend code using Claude and an internal AI prototyping tool. When design changes affect more than one product, I coordinate directly with PMs across systems to make sure nothing breaks.

• Led the design of KIA's Product Pricing System (KPPS) as UX Lead on a 4-person team. KIA's pricing teams across 13 European markets were running entirely through interconnected Excel files with VBA macros. Over 2 months, I mapped their end-to-end process, built the information architecture, and designed a complete React web application with a locking/approval workflow that preserved market flexibility while solving their data integrity problems.
• Designed the configuration module for H&M's new in-house payments portal, replacing SAP Hybris. Built new design system components for admin-facing tools since the existing system only covered the consumer website.
• Contributed to Endava's internal open design system, intended for use across client projects.
• Technical interviewer and career coach for designers at Endava.

• Responsible for UX across the full product surface of Romania's #1 real estate platform (40,000+ daily unique visitors): listing pages, search filters, navigation, agent tools, and internal dashboards.
• Revamped MAP, an agent prospecting tool with 10,000 monthly users. The original version was from 2010. What started as a quick UI refresh turned into a deeper redesign after uncovering structural problems through user interviews and workflow analysis.
• Introduced HotJar to the team, shifting design decisions from assumptions to session recordings, heatmaps, and real user data.
• Designed an internal developers dashboard. The team had already voted on features and started building. Through stakeholder interviews and a workshop mapping how QA and developers actually worked, I found their most requested module, an error log, was redundant: bugs already flowed through Git and no one would have acted on raw errors.

• Designed new features for and/life, a fitness app with meal tracking, exercise tracking, and video workouts. Ran QA before sprint releases.
• Rebuilt the Sketch file into a proper component-based system using Symbols and Nested Symbols, essentially reverse-engineering a design system for handover.

• Built serious games and architectural visualizations in Unity (C#) and Unreal Engine for VR (Oculus, HTC Vive, GearVR) and tablets. Handled interaction logic, feature implementation, design documentation, QA, and optimization.
• Worked with finite state machines, behavior trees, flow graphs, and Unreal Blueprints. Optimized experiences to run on mobile and VR hardware within strict performance constraints.
