Senior Software Engineer · mobile, web & delivery

Earl Hayes

I design and ship products end to end — from architecture and offline data to app-store release and the delivery systems that keep them moving.

I am a Michigan-based full-stack developer specializing in cross-platform mobile and web software. My deepest work is in C#/.NET and .NET MAUI, with React, Python, Azure, SQL, and Linux when a product crosses into web, cloud, or hardware.

Case studies Professional profile

Current scope

I am a Senior Software Engineer at WorkWave, focused on application architecture, shared cross-platform foundations, mentoring, and end-to-end mobile and web delivery. Outside the day job, I publish mobile products, web software, physical designs, and public repositories through Big Bwain LLC.

AI-assisted delivery

I build internal AI tooling and agents used by other engineers, and use LLM-assisted development and design workflows, including Claude, as one part of a delivery system that still includes testing, release engineering, and direct product ownership.

01 / Public evidence

A delivery record you can verify

The professional argument starts with products and artifacts that are already public, not private employer metrics or inflated scope claims.

  • Live mobile products

    5

    Adventure Cache, Rubetris, Cache Creature, Your Whey Fitness, and 3DCDesign.

  • Current store listings

    9

    Five on Google Play and four on the Apple App Store.

  • Mobile ecosystems

    2

    Production delivery across iOS and Android.

  • Public Linux driver

    1

    Keydial Commander adds a native workflow for vendor-unsupported hardware.

02 / Career continuity

One continuous path, increasing scope

Approx. — Present

Continuous employment that began at Real Green Systems around August 2015 and continued without a break when WorkWave acquired the company in June 2021.

03 / Selected work

Engineering decisions in context

Two detailed examples cover the work behind the artifact: constraints, tradeoffs, production failures, and what changed afterward.

04 / Maker range

Software is not the only output

CAD, 3D printing, and functional physical products provide a second kind of evidence: moving from an idea to something another person can download, print, test, or use.

  • Published CAD designs

    60+

    Functional tools, model railroading, device mounts, and maker accessories.

  • Public model downloads

    9k+

    A visible signal that the digital designs are being used.

  • Physical print listings

    50+

    Functional prints, geocache containers, decor, and articulated pieces.
