Technologies: JSON, XML, Unity, C#

Software Developer

2016 - 2019
Prota Software
  • Created DLLs in VB.NET that implemented structural steel design specifications for the UK, US, Europe, and Turkey. This gave ProtaStructure® the ability to design steel structures.
  • Created a tool that was used to generate multiple structural braces between selected regions. This tool increased the productivity of users in complex structures.
  • Developed a tool used in ProtaStructure® and ProtaDetails® that was capable of checking the structural capacity of truss members and optimizing the profiles used among given alternatives.

CitiGenius Atlas is a multi-purpose GIS analysis software used in municipal, real estate and military applications.

CAD-based Overlapping Lattice Mesher

Created a standalone CAD based mesher program using WinForms, C#, and GDI+ for overlapping lattice modeling (OLM) applications. This is similar to finite element modeling (FEM), but stronger in solving irregular materials challenges. The program has integration to confidential University OLM solver engine, and gnuplot, which is the most popular graphical tool in scientific applications.

Firebowl: 3D Bowling Game

This is a casual single-player 3D mobile bowling game made in Unity using test-driven development for score calculations. Implemented a curved ball mechanism by drawing a curve pattern on the screen to throw the ball.
