Projects I'm proud of

Booking platforms with payments, mobile apps, PWA platforms and my own AI — each one built end to end, from idea to launch.

AI model

GAYA

My own computer-vision system: from one bouquet photo it identifies flower species and varieties, counts heads and stems, and describes color and wrapping. Runs on a CPU, no GPU.

A family task and rewards app: parents assign and review tasks, kids complete them, earn points and redeem them for rewards. It also has a section of 23 mini-games and a subscription with plans and a free trial.

What I do

Web and mobile, front to back

Six areas I work in on client projects; the demo in each tile is plain CSS.

Mobile apps

React Native apps for iOS and Android from a single codebase.

@Controller("v1/projects")export class ProjectsController {  @Get() list() {    return this.projects.list(locale);  }}

Full-stack

Next.js, NestJS, Prisma, PostgreSQL, CI/CD and deployment on my own servers.

Payments & booking

Checkout and booking flows: payment step, bank-hosted payment page, seat and time holds.

From idea to launch

Business logic worked out with the client, hypothesis testing, UI/UX designed with AI tools, admin panels and support after release.

AI & computer vision

Datasets, training and CPU-only serving of my own models.

Performance, SEO & motion

Core Web Vitals, SSR/SSG, bundle budgets, plus GSAP and Three.js animation where it helps.

My AI

GAYA reads a bouquet from one photo

A computer-vision model I built and trained: species, varieties, number of heads, colors, wrapping — about half a second per photo, no GPU.
