Values

How I like to work and collaborate. Clear communication, respect for every voice, and keeping delivery quality high without ego.

  • Transparency first: share context early, document decisions.
  • Team over ego: best idea wins, not the loudest.
  • Healthy debate: challenge ideas, not people.
  • Craft & cleanliness: tidy code, tidy backlog, tidy Figma.

What you can expect from me

People

  • Encourage, unblock, listen.

Work Experiences

R&D Engineer — Asyril

Frontend Engineer

Vue / TypeScriptVuetifygRPCUX ResearchDesignPython

Building EYE+ with operators in the loop — sketch, test, refine, then ship small so the line never slows down.

  • Co-led discovery: workshops → Figma prototypes → moderated user tests.
  • Shipped Vue + TypeScript features wired to Python via gRPC.
  • Tightened feedback with PM/PO and QA to trim cycle time.

Impact

Onboarding

UIs mapped to operator flow, cutting handover coaching time.

Iteration

Design–dev syncs reduced rework; features hit review with fewer spins.
