I build games — and the systems behind them.
I engineer high-performance systems and gameplay mechanics from scratch. Whether it's building O(1) data structures in Unity or resilient microservices in Node.js, I believe in strict constraints, testable architecture, and zero bloat.

- Open for Internships
I am a systems-oriented engineer obsessed with how things work under the hood. While I love designing engaging game loops in Unity, I am equally passionate about architecting the backend services, databases, and APIs that support them.
My development philosophy relies on strict constraints: I write C# and Node.js code that avoids unnecessary abstractions, minimizing GC spikes and keeping memory profiles lean. I frequently implement custom object pools, deterministic data structures, and custom ML pipelines using Python.
When I'm not studying at NIT Jalandhar or participating in Game Jams, I am likely breaking down classic game mechanics, learning low-level C++, or optimizing full-stack applications.
Quests & Experience
Professional timeline, internships, and educational milestones.
Game Development Intern
- Independently developed and published 21 HTML5 games using JavaScript, Phaser, HTML5, and CSS from reference games, concepts, and gameplay prompts.
- Used AI-assisted development workflows (GitHub Copilot and Google Gemini) for rapid code iteration, debugging, and selected asset workflows while retaining full engineering ownership of the final implementation.
- Contributed all 21 shipped games to Aicade's platform and RAG pipeline for AI-driven game generation; one title remained in the platform's Top 5 games for approximately 8 months.
Shipped Commercial Release: Snake on Google Play
- Engineered and shipped a commercial Snake release on the Google Play Store (`com.BeerStudios.Snake`) built around an O(1) `LinkedList<SnakeSegmentData>` + `HashSet<Vector2Int>` movement and collision core.
- Built runtime aspect-ratio camera framing (`GridCameraScaler`), cross-platform buffered swipe/keyboard input, native Android haptics, and a 12-segment autonomous attract-mode AI snake.
GMTK Game Jam Entry: Bomb Massacre
- Extended Unity 6's 2D Platformer Microgame template under jam deadline pressure with an original "cook-to-throw" bomb mechanic (discrete 1–3 unit blast scaling over a 5s hold timer, backed by a fixed pool of 3 bombs).
- Implemented circular tilemap crater carving (`DestroyTilesInRadius`), procedural fallback explosion sprite generation, single-scene spawn-point level switching, and Tiled (`.tmx`) level pipelines.
B.Tech, Computer Science & Engineering
- Coursework and independent engineering across Data Structures & Algorithms, Operating Systems, Computer Networks, Database Management Systems, and Machine Learning.
- Built campus-scale architectural prototypes including the NITJ Academic Resource & Notes Exchange System and the Student Complaint Classifier System.
