Work Experience

Senior Software Developer and Architect

2006 - 2020
Astron (Lindab Building Systems)
  • Developed a design system for structural engineers.
  • Created calculation and optimization algorithms with industrial and academic professionals.
  • Created a module, which created a bar model and meshes for finite element solvers automatically.
  • Maintained a configuration database in Microsoft SQL.
Technologies: C++17, C++14, C++11, Visual Studio, PTC Mathcad, CAD, Subversion (SVN), C++

Software Architect and Senior Software Developer

1998 - 2006
Graphisoft
  • Created an automatic roof beam generator module for ArchiCAD. This was the first external C++ module (add-on) for the company.
  • Developed a log home designer module for ArchiCAD. It had a log cut machine driver interface that could be customized in Perl.
  • Contributed to the team that created the 5D presenter; it was a product that simulated the building process and the cost scenario.
  • Created customized versions of ArchiCAD to satisfy the demands of different customers.
Technologies: Windows, MacOS, Desktop App Development, Desktop App Design, OpenGL, Perl, Visual Studio, 3D CAD, C++

Software Developer

1996 - 1998
ALSTOM Transport
  • Developed a GUI for a railway control system on the X Window System (X11).
  • Collaborated with Italian railway engineers and GUI designers in a remote environment.
  • Created a long-time testing environment of the system to find problems after a run of several weeks.
  • Handled events that come from vital railway system and from the user, in multithreaded way.
Technologies: Desktop App Development, Desktop App Design, Bash Script, Graphical User Interface (GUI), Unix, Motif, C++

Software Developer

1994 - 1996
Peter Darvas Ltd.
  • Developed printed circuit board design software on Unix.
  • Maintained legacy C and C++ code, and used a source control system.
  • Handled user requests and improved software functionalities.
Technologies: C++, C, CAD, Unix, X11

Template-based Code Generator

A visual studio extension which accesses the C++ syntax information and generates various kind of sources, for example, Delphi interface, scripting layer over C++, and persistence layer too. It ensures error-free code and avoids mechanical programming.

Automatic Steel Joints Design

An algorithm that optimizes the use of steel, welding work, and screws where two steel beams join to each other in a steel building. I worked together with steel engineers and academic professionals to design the algorithm.

Genetic Optimization of Wood Consumption for Log Houses

A log home builder company wanted to optimize the usage of logs while they keep some hard constraints. I planned and developed a solution that used a genetic algorithm to achieve this. It has been used for years there in their industrial environment.

Epidemic Spread Simulation

http://www.natisoft.hu/ENTS/indexFullPub.html
This is a pet project. I made a simple epidemic simulation that works in a browser. Many parameters can be set in the JavaScript interface. It calculated some probability, for example, when someone makes contact with the virus, goes to the hospital, etc. It can be accessed on git too.
