## What sets him apart

- **Full-spectrum frontend** — a rare blend of UX/UI design sense *and* deep engineering. Bridges design and code so intent survives the handoff, from the first wireframe to production.
- **Design & UX craft** — runs user-centred UX work end to end: user flows and information architecture, wireframing and interaction prototyping in Figma, and visual UI design — typography, layout, spacing and motion — rooted in a Digital Media / graphic-design background. Validates ideas early with greenfield prototypes.
- **Vue & Nuxt at scale** — designs maintainable, scalable frontend architectures and reusable template systems that keep multi-project delivery fast and consistent.
- **Design systems & accessibility** — builds clean, accessible (a11y), consistent component libraries that large products can grow on without slowing down.
- **Cross-platform mobile** — ships native iOS & Android apps with Flutter/Dart, including offline-first experiences for demanding field scenarios.
- **Headless & composable** — fluent across modern CMS and e-commerce backends, wiring frontends to headless and composable architectures.
- **AI engineering** — works hands-on with AI integrations, prompts, agent workflows and harness systems for autonomous agents; has led feasibility research into agentic commerce for enterprise.
- **Leadership & management** — end-to-end project ownership and team lead in agile (Scrum/Kanban) settings: project and stakeholder management, planning, mentoring and code review. A clear translator between business, UX and engineering. Pragmatic solutions over tech dogma.
- **Domain range** — editorial/content platforms, B2B and B2C e-commerce, and regulated industries such as healthcare.
- **Community** — long-time organiser in the regional web/tech scene: events, speaker curation and knowledge sharing.

## Ways of working

- **Curiosity & continuous learning** — genuinely curious and always ready to pick up new tools, frameworks and domains; ramps up fast and stays current through hands-on side projects and research (most recently AI engineering and agentic commerce).
- **Calm under pressure** — keeps a cool head in stressful situations: structured prioritisation, clear decisions and reliable delivery even on tight deadlines.
- **Ownership & collaboration** — takes end-to-end responsibility, coordinates stakeholders and steers agile teams; bridges business, design and engineering with clear, jargon-free communication, and shares knowledge through mentoring and workshops.
