ABOUT ME

Full-stack mentor; C# in every domain; Backend, React, Unity and more.

Consultant and full-stack software developer and consultant.

Currently an AI service and application development consultant.
Backend specialist for 5 years at S&P and Banqsoft.
Mobile specialist for 7 years with Diversido, Noble Muffins and other clients.
Professional experience with Python, React, TypeScript, C++ and Java.

I got my start when I took over IT at a horse trailer dealership to gather money to move to Europe.

At AI Horizons, I built a complete AI entertainment product, including advanced and precise content filters necessary for monetization.

At S&P, I took our team's first two microservices from zero to production. I later served as scrum master, and was given a technical excellence award for my work in SQL optimization.

As a game developer, my Turbo Slicer product has been featured repeatedly by the Unity Asset Store. I wrote a finite element analysis kit for PlayWay S.A. to manage building collapse for the games Construction Machines 2016, Demolish & Build 2017 and Demolish & Build 2018.

On CodeMentor (Arc), I help developers with interesting problems. Some highlights:

Helped an experienced engineer build a Gtk-based UI for an industrial control unit.
Helped an entrepreneur deliver a Unity-based VR demo to customers and investors.
Debugged problems of concurrency, thread safety and asynchronous IO in iOS apps.
Lead a student through correct authoring of a filesystem driver.

C++ is the power tool I grab for special projects. I converted a 288 gigabyte map of laser altimeter data from the NASA Lunar Reconnaissance Orbiter from mercator projection to cubic. I wrote a multiplatform thin client. I wrote an iOS tactical game with OpenGL ES. In a project on Codementor, I helped a mentee working in C build a UI for an industrial control system. I enjoy working with it.

Great Explanation of how to break down and find code issues.

Ok. So Joe told me up front that he knew little about machine learning - which was the issue I was working on. But he said he was interested and would do the session on an "at risk" basis - i.e. no solution, no payment required. He sounded super smart - so how could I refuse? Turns out that Joe was able to work with me diving deep into the structure of the package (Tensorflow) we were working with (which btw he hadn't worked with before) and together we were able to figure out a solution. The moral to me is that someone who is smart and thoughtful but new to an area can be 100 times more useful than someone who knows something about the area but is not a smart diagnostician. In summary - Great Job! Thank you Joe! Would definitely use again

Excellent, something I was racking my brain over half a day took Joe less than 30 minutes to fix.

I have been a embedded real-time software engineer for 40+ years but was having difficulty designing a complex GUI with GTK. Joe helped me do things in a few hours that would have taken me weeks to learn and do on my own. In addition to helping me get it done, he was very good at mentoring me and making sure I understood what we were doing. I will continue to use Joe anytime I need help.

Turbo Slicer is an easy and performant way to shred a mesh on a mobile. I wrote Turbo Slicer in C# for the Unity Asset Store in 2012, and it remains in use today. Turbo Slicer's key features are its edge loop detection to cover holes on non-simple objects, the use of threading, and cache-aware programming techniques to perform even on modest systems.
