FOSS Compliance Services

https://bearingpoint.services/foss/en/
A B2B service offering FOSS (free and open-source software) compliance and security assessment and management offered by BearingPoint, based on an ecosystem of applications and tools that my team and I developed. As a technical leader, I chose and adapted the technology stack, set up and managed development and production servers, architected software solutions, coached team members, and helped them hone their skills and competencies.

Alphabetty Saga

https://www.king.com/game/alphabetty
A successful letter-linking mobile game by King, the studio behind the well-known Candy Crush franchise. I was one of the four C++ developers on the game client, working on everything from the graphics pipeline and game mechanics to menus, analytics, and integration with social platform APIs. We took the game from a prototype stage all the way to solid production quality, working closely in the process with the back-end team in charge of the game data servers and with the stakeholders who offered guidance to achieve financial success.

Double Dare

https://play.google.com/store/apps/details?id=de.imc.doubledare&hl=en_IN&gl=US
Challenge-oriented social platforms for corporate environments developed at IMC AG. I worked as a front-end developer on this hybrid web and mobile app. Some of my personal achievements in the project were optimizing the responsiveness of the layout, improving the application's performance, adding new features such as support for video uploads, and implementing various sections and elements of the user interface.

IxNetwork

https://www.keysight.com/zz/en/products/network-test/protocol-load-test/ixnetwork.html
A network infrastructure performance testing applications developed at Ixia (nowadays Keysight). I developed the licensing system for these applications, along with diagnostic and live debugging tools.

Tom Clancy's H.A.W.X. and H.A.W.X. 2

https://www.ubisoft.com/en-gb/game/tom-clancy/hawx-2
The first and second iteration of the air combat game developed by Ubisoft. I had various roles on these projects, such as:
• Gameplay, physics, and AI developer (Nintendo Wii version)
• Render and graphics developer (Xbox 360 version)

Assassin's Creed Brotherhood

https://www.ubisoft.com/en-gb/game/assassins-creed/brotherhood
An action-oriented brother to Prince of Persia, the Assassin's Creed franchise was a great success for Ubisoft. As a UI/UX developer, I was responsible for the game's user interface - menus, settings, messaging and tutorial system.

Omega-Y

https://github.com/bog2k3/omega-Y
This was a solo attempt at a cross-platform—a 3D first-person shooter based on OpenGL graphics API and procedurally generated environments.
The project is far from complete, but it is functional and showcases advanced water rendering effects, various procedural generation techniques, a custom UI layout engine, networking, and physics simulation in 3D.
I have not used any game frameworks or engines; apart from the Bullet 3D physics library, I have developed everything else.

Artificial Life Simulator

https://github.com/bog2k3/bugs
This is a lengthy project internally known as "Bugs" (due to the semblance the creatures bear to actual insects) that I undertook by myself. It was the attempt to produce a simulation of life free enough in its expression to be able to give rise to unexpected creatures and species, arms races between them, and, eventually, intelligence.

The creatures in the simulation are built procedurally as dictated by their genome, and so are their neural networks that govern their senses, muscles, movement, and reactions. The creatures suffer mutations and breed, evolving by natural selection.

XScript

https://github.com/bog2k3/xscript
A custom strongly-typed scripting language implemented in Java, complete with its own multi-threading runtime, GUI API, and interfacing with Java classes. It can be used in Java applications to enable custom extensions by scripting or to write small graphical applets that can be integrated into a virtual desktop.
I developed this project entirely on my own.
