React, Next.js + purposeful AI
I turn complex ideas into responsive, maintainable interfaces and add AI only when it solves a real user need.

03 / Evidence ledger
Four real constraints, traced from problem to implementation. No self-rated bars and no invented impact numbers.
Constraint -> decision -> system -> evidence
Core decision
High-risk support needs predictable behaviour, instant access and privacy before novelty. The product switches away from generative responses when risk is detected.
Implementation choice
Deterministic crisis pathways with offline-first resources.

04 / What I bring
The best interface is the visible tip of good decisions underneath.
Explore the toolkitResponsive, accessible product interfaces built with Next.js, React and TypeScript—with architecture that stays understandable after launch.
AI features shaped around a real user need: private support, useful summaries and smarter workflows instead of another chat box.
From content structure and interaction design to performance, QA and handover. I build the whole experience, not just the screen.
05 / Working principles
Design is not decoration. It is how a product explains itself before a user has to ask.
I build digital products that feel calm, move with intention, and respect the people using them.
Make the next action feel obvious.
Give the product a voice of its own.
Build for the person behind the screen.
06 / Experiments · interface laboratory
Design is a system of decisions. Change the intent and the interface should respond.
Give the same system a different emotional job.
Start with a mode, then fine-tune it. The preview is driven by the same design tokens as the controls.
Live product surface
Calm preset / 78.18.72
A quiet surface for moments that need reassurance before action.
Native controls, semantic states, reduced-motion support. The experiment is part of the interface—not layered over it.
