Senior Software Engineer. Founder of Big Bwain LLC.
My beautiful wife, daughter, and my family are the reason behind my endless drive (with a bit of ADHD). Taking care of them is what drives me to keep learning, building, and delivering.
I build across mobile, web, desktop, cloud, and hardware. My career spans from technical support, QA/Automation, into software engineering, architecture, and mentoring. I honestly just like creating and occasionally dive into additive engineering, CAD, and designing models to solve everyday problems.
| Part of the work | What I take on |
|---|---|
| Understand & design | Real user needs, architecture, data models, and practical tradeoffs. |
| Build & connect | Cross-platform clients, APIs, offline data, cloud services, and hardware integrations. |
| Test & deliver | QA, automation, accessibility, deployments, and app-store releases. |
| Support & improve | Troubleshooting, maintenance, iteration, and helping other engineers grow. |

Real products, useful tools, and games with a little personality. These are selected projects across my recent work; their links show current availability.
- Model Scout: A local Windows workbench for 3D models, previews, duplicate review, safe transfers, and print-cost estimates. Explore the source.
- Rubetris: Debrix, Rosette, and Erikade. Three gem-cutting puzzles with distinct rules, seeded runs, and replayable challenges. Play in the browser.
- Doodle Bluff: A drawing-and-bluffing party game. Sketch something strange, invent a convincing answer, and discover who fooled whom. Free beta.
- Your Whey Fitness: Workout planning, session logging, history, and progress, with a wider platform for personal fitness and trainer or gym workflows.
- Adventure Cache: Create outdoor adventures, hide caches, follow clues, log finds, and earn badges. Mobile engineering that gets people away from their desks.
- 3DCDesign: Local print-shop tools for printers, materials, jobs, estimates, and reports, built around the practical work of making physical things.
- Cache Creature: Collectible cards inspired by moments, signals, prompts, and scans.
- Cache Pal: Hatch, raise, battle, and breed living pixel creatures in an offline-capable browser game.
- City Jumper: A rooftop platformer. Chase the sunset, find your rhythm, and climb the leaderboard.
- Wordsracer: Race through Word Arena or explore a letter tray in Word Garden.
- Keydial Commander: A Linux driver and visual macro-pad editor for the Huion K20, with profiles, shortcuts, and a local API. MIT source.
- Cacheboard: A local workbench for planning and coordinating AI-assisted development. Private project in development; included in the AI project catalog.
Also on my workbench: Pocket Words, a quiet offline Android word game with large controls, accessible clues, and no accounts or ads. Currently a development build.
Away from app screens, I design functional CAD and 3D prints, experiment with MAUI 3D painting, and work on rubybiscuits e-paper firmware.
| Where | Tools |
|---|---|
| Mobile & desktop | C#, .NET, MAUI, WPF, Swift, Kotlin, Java, Electron |
| Web & games | TypeScript, React, Astro, Phaser, Godot |
| Services & data | ASP.NET Core, Node.js, SQL, SQLite, Azure |
| Hardware & making | Python, Linux, CAD, additive manufacturing |
The stack follows the problem. The goal is a product people can use, trust, and keep using.
