Registration and event platform

IBL Youth Conference

The problem

A Houston youth conference needed teens to register themselves, youth leaders to pay for their whole group at once, and staff to run check-in, points and a sports tournament during the event.

What I built

• A public registration site where teens sign up on their own
• Bulk group payments for youth leaders through Stripe Checkout
• An admin panel with separate roles for check-in, points and the tournament

Interactive displays + admin

Missions Displays

The problem

A church's missions boards ran on a PowerPoint file that had grown past a gigabyte. Every update was slow to sync, and sometimes someone had to restart it by hand.

What I built

• An interactive website where members explore the missionaries the church supports
• An admin page to add and edit missionaries, photos and prayer letters, with no file to re-sync
• Mini PCs and repurposed SMART Boards on scheduled smart plugs, so the displays turn on and off by themselves

Production tracker

Bootline

Private client project

The problem

A western-boot maker takes orders in Houston and builds the boots in Mexico. Production was tracked on paper cards and sheets across two countries.

What I built

• A mobile-first tracker that mirrors the factory's real paperwork: production cards, size grids and order sheets
• A stage board that follows every batch from cutting to shipping, with a reason required whenever work pauses
• Roles for owners, factory admins, production workers and sales, in Spanish first with an English toggle

Personal site and writing

ismaeldiaz.com

The problem

An engineering student needed one home for a resume, projects and years of class notes and reflections, and it had to stay easy to keep adding to.

What I built

• A home page where circuit-board traces route themselves across the screen, drawn live on a canvas
• Projects, course write-ups, game reviews and Bible reflections kept as Markdown files, so a new post is just a new file
• A resume page with a downloadable PDF
