- Build
- Events discovery, private and public event planning with RSVPs and attendee tracking, and paid ticket sales. In production and maintained for several years.

Marché Dieppe Market
Site migration and self-hosted infrastructure, Dieppe, New Brunswick
- Last release
- ongoing
- Status
- Live
- Context
- The market's Next.js site was on Squarespace. They wanted it on infrastructure they control, without downtime, and with someone to keep it running.
- Build
- Migrated the site onto a Linode VPS that I provisioned and administer end to end with Docker and Coolify. Ran the live DNS cutover through GoDaddy, then hardened the deployment with a network-level cloud firewall after finding that Docker bypasses host-level UFW rules.Next.jsLinode VPSDockerCoolifyGoDaddy DNS

- Context
- Event organisers needed paid audience voting that works on smartphones and basic phones, and pays out without waiting on cycles.
- Build
- Web and USSD voting, per-vote payments, fraud controls, instant payouts in Ghana and Nigeria, an API and embeddable widgets. Self-hosted on a VPS with Docker and Coolify, which I run and maintain.Next.jsExpressTypeScriptFirebaseDockerCoolifyVPS

Deployment and hosting
I deploy and run what I build. Linux server administration, VPS provisioning, Docker, Coolify, DNS management and live cutovers, SSL, firewall configuration, backups. Uzeka, BuddyVotes and the Marché Dieppe site all run on VPS infrastructure I migrated them to and maintain.
Now
My own venture, in progress.
- Problem
- Last-mile couriers in Ghana lose whole routes to calls, landmark hunting, waiting, and parcels nobody could collect.
- Build
- One dense run to a secure endpoint; recipients collect later with a private code. Same problem space as Flip, larger scope. I'm building it end to end.
