Experience
Contract Full-Stack Developer | TheTripMan
Aug 2025 - Present
Remote, Ontario | thetripman.com
- Replaced manual phone and direct message bookings for a brand with a 1.7M-follower audience with a Next.js, TypeScript and PostgreSQL platform built solo, now handling 11 to 13 bookings in a peak month.
- Ended unpaid reservations: a booking is confirmed only after Stripe's signed webhook reports the payment as settled.
- Built an authenticated admin dashboard over Prisma and PostgreSQL that ended the owner's daily dependency on a developer; paid bookings trigger Resend emails and Google Calendar events.
- Protect releases with Jest, jest-axe and CI before each Vercel deploy, and own production support.
Freelance Web Developer | Puuffy Bakery & Ice Cream
2026 - Present
Toronto, ON | puuffy.ca
- Launched the bakery's first site (Next.js, live hours, 12 unit tests) and fixed five problems an audit found, from a Google block to a form losing every email and an exposed personal phone number.

2026 - Present
React, TypeScript, Vite, Supabase, PostgreSQL, Zustand, Tailwind CSS, PWA | Live Demo
