   A concurrent venture that currently occupies my active life: a creative studio for high-end branding, web design and custom development.

   • Selected work: Alumed (a premium aesthetic medicine clinic), Printly (a B2B print platform) and the full brand identity for Squizzu.
   • Built Venor, an in-house lead generation platform that sources and qualifies prospects for branding studios.

   • Designed 100+ original responsive screens, custom icons and a consistent design system in Adobe XD, without using pre-made UI templates.
   • Lead frontend development with TypeScript, React 19 and Next.js: accessible interfaces, dark mode and reusable components.
   • Established an API-first integration workflow using OpenAPI/Swagger-generated TypeScript clients, and collaborate with the backend team on .NET 8 APIs, authentication and payments.
   • Designed and implemented the gamification experience, including leaderboards, learning streaks, progress tracking and multiple learning modes.
   • Integrated GPT-4o product agents with self-healing validation of malformed JSON.
   • Built AI-assisted development tooling, including a production MCP server, automated quality gates and reusable Claude Code workflows.

   Two years across three stages: a year-long industrial placement, part-time work through my final year of study, and a full-time return after graduating, on platform and identity work.

   • Led the university's Website Development Service: 21 sites during the placement and 30+ in total, for researchers and for projects including OSCE, Physiotherapy Clinic and Aerospace.
   • Worked out an Elementor-based solution that simplifies content population for editors, and wrote the guides and stakeholder support around it.
   • Redesigned “NU Connect”, the university mobile app used by 40,000+ people: wireframes and a fully interactive prototype in Adobe XD, then implementation alongside the IT Services development team (XAML, C#, .NET, Xamarin, Azure Storage). The redesign lifted active users by 40%.
