This unique blend of skills ensures I am at the forefront of innovative game development, thereby enhancing the gaming experience for players across the globe. My foray into game development commenced at Lazy8Games as a Software Engineer, where I designed and prototyped scalable, reliable game interfaces using Unity Engine and Photon Networking. I have a history of creating award-winning, visually compelling and technically challenging games such as: "Dystopian Skies" - recognised as the #1 Mobile Game at an inter-collegiate game-dev competition. It is a multiplayer 3D game set in a post-apocalyptic scenario, using a variation of the ROAM algorithm for earth simulation. In the game, players combat space drones to reclaim infested land on earth. "Arcane Aero" - A side-scrolling action arcade game for Android, developed as part of an entrepreneurial project Blooming Pixel, and live on the Google Play Store. In my subsequent role as a Software Engineer, I designed and developed intricate engineering applications using multiple programming languages and frameworks, including Java, C++, OpenSceneGraph, OpenGL, Qt, and C# across Windows, Linux, and Android platforms. Here, I particularly worked on GIS Applications, where I developed modules in the digital graphics domain, leveraging my understanding of performance graphics, a crucial component in game development. I also designed a GPS-based tracking application on Android with map caching, besides maintaining a software SDK stack on Linux. My technical prowess extends to Service reliability, System design, Kubernetes, Java, Kafka, Protobuf, BigData platforms (Apache Hadoop/Hive/Oozie/Spark), C#, Python, Perl, MVC Frameworks, JavaScript Frameworks, and Android app development, backed by an engineering degree from IIT Bombay (Mumbai), a leading engineering university in Asia. As a thought leader, I enjoy exploring and speaking about the intersection of AI, game development, and backend engineering, and frequently share these insights through technical speaking engagements.
