Teacher first. Builder, too.

I teach elementary math and science in Florida, and I like building tools for the parts of school that get loud, repetitive, weirdly complicated, or all three at once.

Before teaching, I worked in school IT. That meant devices, accounts, staff support, student devices, clear notes, and a lot of "can you come look at this real quick?"

I mean, come on, it looks exactly like me!

From classroom problems to projects.

A few of the tools I have been building, with room to explore each one.

What Shapes the Work

Classroom teaching, teacher support, and school IT all show up in the way I build.

Classroom work

I taught 3rd grade math and science from 2022 to 2025, taught 4th grade math and science during the 2025-2026 school year, and am slated to teach 5th grade math and science for 2026-2027. So yes, I have strong opinions about directions, pacing, and whether a button is big enough for a kid using a shared screen from across the room.

Teacher support

I have helped with grade-level leadership, PLCs, shared teacher resources, assessments, and training. I like helping teachers get from "this thing exists" to "I can actually use this on Tuesday without losing my mind."

School support roots

I worked for the School District of Osceola County before teaching, supporting staff, students, devices, accounts, and all the tiny mysteries that show up five minutes before the bell rings.

Make it useful before making it fancy.

I care about polish, but the first test is simple: can someone use this without needing a mini training session?

Start with the room

A classroom tool has to survive noise, borrowed devices, short attention spans, mystery Wi-Fi, and a teacher who is already doing six things. If it only works in a quiet demo, it does not really work.

Write it down

I like clear notes, checklists, and examples that answer the next obvious question. Future me is one of the people I keep notes for, and that guy forgets things.

Keep the door open

Most tools need edits later because people keep having new ideas. I try to build things in a way that makes the next update feel like a normal afternoon job, not a weekend project by accident.

Work With Me

I like small projects with a real reason to exist: classroom tools, practical websites, cleaner training materials, and the occasional "surely this can be easier" idea.
