wgmesh
wgmesh keeps a WireGuard mesh in sync without hand-editing configs. It follows peers whose IP addresses change, clears stale NAT sessions and corrects configuration drift. Written in Go and shipped as a systemd service.
Software built on a working Texas ranch.
I run a drone spraying business, a construction crew, and a ranch and farm in D'Hanis, Texas. The apps on this page were written to run those businesses. I use them every day, and you can too.
Apps
Each one started as a tool for my own outfit. They run in the browser first; phone apps follow where they earn their place.
Built for real businesses. Available for yours.
These systems run day to day at my own operations and at a friend's restaurant. If you run a restaurant, a dealership or a shop and want the same setup, I can put it on your server or mine.
-
Online ordering with a text message to the kitchen on every order, an order screen that stays open all shift, a table mode so waitstaff order by table number, menu search, and a back office for prices, descriptions and plate photos. Installs on a fresh Ubuntu server with one script.
-
SkyField Ag
Website for a dealership selling refurbished DJI Agras spray drones: inventory, financing and contact, built as a fast static site with no platform fees.
-
Storefront with Stripe checkout, product information pages and a reconstitution calculator that does the dilution math for you.
Open source and experiments
Infrastructure I needed for my own servers, and one project that taught me more by failing than by working.
TradeStation trading engine
A Go engine with a React dashboard for the TradeStation API: strategy backtesting, walk-forward optimization and live trading, hardened for unattended runs. Private.
The honest result: none of the bundled technical strategies consistently beat buy-and-hold on the instruments I tested.
About
I'm A. Correia, a developer in D'Hanis, Texas. I also run a drone spraying business, a construction crew, and a ranch and farm with eggs, bees and a floral nursery. Every app on this page exists because one of those businesses needed it, or because a friend's did, and each one is still in use every day.
What I build with: Go and Postgres on the back end, React and Expo up front, Ubuntu and Caddy underneath, self-hosted. When I take on custom work, that is the stack you get, along with an installer so your server comes up in one step.
