Scroll down naturally. Each project stacks smoothly like an engineering dossier.
Local-first mobile app featuring zero-latency peer-to-peer encrypted sync. Operates 100% offline without central databases or third-party tracking.
Real-time 2D avatar motion engine powered by in-browser computer vision. Achieves stable 60 FPS by offloading TensorFlow.js inference to background Web Workers.
Customizable digital invitations platform for social events. Features background music playback, interactive maps, RSVP tracking, and dynamic theme catalogs.
Production ecosystem of 22 engineering tools built under strict SOLID principles: OKLCH gamut color engine, open MCP specification builders, and a hybrid AI assistant.
Architected a unified multi-brand Next.js platform serving 5 educational organizations concurrently. Cut deployment overhead by 40% through standardized Docker and AWS S3/CloudFront workflows.

From system design to production deployment with clean code.
Utilities designed with clean SOLID architecture and local computation. Solving real engineering problems with zero tracking or cookies.
Pure TypeScript mathematical color engine featuring CSS Color 4 binary-search gamut mapping. Exports to Tailwind v4, CSS variables, and DTCG tokens.
// OKLCH Gamut Mapping Algorithm
export function fitIntoGamut(oklch: OKLCH): OKLCH {
let low = 0, high = oklch.c;
for (let i = 0; i < 20; i++) {
const mid = (low + high) / 2;
if (inGamut({ ...oklch, c: mid })) low = mid;
else high = mid;
}
return { ...oklch, c: low };
