Software engineer · Applied mathematician

Hi, I’m Mike.

I build web applications and native tools. I also diagnose and repair electronics, which is how I ended up writing a PCB diagnostics app.

My professional frontend work is in SvelteKit and TypeScript. My current independent project, Ratsnest, brings software and the workbench together.

A little context

Software is the main thread but not the only one

I’ve owned the frontend of a game-services web platform, maintained Minecraft server software for a volunteer community, and shipped a Safari extension. Lately, I’ve been building tools for electronics diagnostics.

My MS is in Applied Mathematics, with research in nonlinear differential equations. I’ve also taught algebra and statistics. That background shows up in how I reason about state, models, and what a test actually demonstrates.

I particularly enjoy Swift’s readability and type system. I like TypeScript for making application contracts explicit. And when a board won’t boot, I’d rather follow the signal than start swapping parts.

02 / Independent hardware repair

A broken eMMC signal path

A Nintendo Switch had eMMC signals at the Tegra side that weren’t reaching the daughterboard. I traced the damaged CMD connection and restored the path with fine-gauge wire.

Evidence
Signal-level checks of CMD, CLK, and DAT0.
Repair
Restored the CMD path and secured it with solder mask.

Tweaks for Reddit

A Safari extension for the old Reddit interface, built mostly in SwiftUI. The work included releases, user-reported bugs, a settings interface, and compatibility changes as Safari evolved.

Engineering
An adapted Composable Architecture pattern for application state.
Lifecycle
Shipped to external users, maintained, then archived when the underlying site changed.

Job aggregator

A local Python pipeline for collecting job listings from different sources, filtering them, and storing them in SQLite. A Flask interface and command-line workflow make the results inspectable.

Data work
Source adapters, normalization, and cross-source deduplication.
Interfaces
A web UI and CLI over the same stored listings.

    MS in Applied Mathematics

    University of Texas Rio Grande Valley · Education

    Graduate research on nonlinear dispersive differential equations and peaked-wave solutions. Additional teaching experience includes algebra and introductory statistics.

    Research context

    The thesis studied how peaked-soliton solutions behave as a parameter changes in a cubic Camassa–Holm model. This is mathematical research, not a claim that the software projects are numerical-simulation products.

    The project statuses matter: professional work, volunteer engineering, shipped products, and independent development are kept distinct. The PCB image is an illustration, not a product screenshot.
