Real-time 3D shoe customizer

Frontend Engineer — 3D & interaction

PLACEHOLDER — replace with your ~150-word narrative from Friday night's content session: the problem (letting shoppers design their own pair in the browser), your approach (Vue app driving a Three.js scene: materials, texture swaps, camera choreography, performance on mid-range devices), and the outcome. No client imagery — the embedded team video and your own abstract diagram carry the visual.

Design system & SCSS component library

Senior Frontend Engineer — design system owner

PLACEHOLDER — narrative: the problem (consistency and velocity across teams shipping on one platform), your approach (token architecture, SCSS component library, Storybook documentation, contribution model), and the outcome. Visual slot: an architecture diagram of the token/component hierarchy you authored — your thinking, not their assets.

  • Design Tokens
  • Storybook
  • Figma

Sole technical lead across the full stack

Technical Lead — frontend, APIs, infrastructure

PLACEHOLDER — narrative: inheriting a production system as the only engineer, stabilizing it, owning frontend through NestJS/Express APIs, PostgreSQL, AWS, and the Python/TensorFlow ML pipeline integration; the architecture audit and documentation eliminating single-point-of-failure risk. Visual slot: system architecture diagram.
