A chronological timeline of my professional work experience.
Unity Developer
Sky Vanguard 3D (3D Aerial Combat – Unity URP)
- ■Engineered a responsive flight control system and a modular, extensible weapon framework handling Homing Missiles, Free-fall Bombs, and Defensive Flares.
- ■Programmed tactical dogfight combat AI behaviors using Unity AI Navigation and Dreamteck Splines for aerial and ground target routines.
- ■Optimized mobile frame rates by implementing memory-efficient Object Pooling systems and custom lightweight URP post-processing shaders (volumetric fog, motion blur).
Sorting3DGame (3D Casual Puzzle – Unity)
- ■Authored core 'Bead Sort' touch interaction mechanics using DOTween to deliver high-performance gameplay feedback and tactile animations.
- ■Architected a scalable chapter progression system featuring procedural challenge generation and a dynamic shop/currency economy.
- ■Integrated Unity LevelPlay for ad monetization and engineered custom PerformanceManager to log player accuracy and level completion efficiency.
- ■Developed an intelligent hint generation algorithm and pathfinding-based 'Undo' stack mechanism to improve retention.
Machine Learning Intern
Conversational AI & Predictive Analytics
- ■Improved NLP data extraction accuracy by 30% by developing and deploying RASA-based conversational AI integrations for mobile applications.
- ■Migrated FastAPI backend services to Azure Functions, optimizing serverless scalability and resource availability.
- ■Built predictive neural network models using TensorFlow/Keras to process operational datasets, visualizing system telemetry via Power BI dashboards.
Featured Projects
Sky Vanguard 3D
Engineered a responsive flight control system with modular weapon systems (homing missiles, free-fall bombs, flares), custom tactical dogfight AI, and mobile frame-rate optimization.
Donut Sort - 3D Casual Game
Designed and published a complete hyper-casual 3D puzzle game. Developed core gameplay logic, virtual economy, level editor, inventory system, and mediated ad networks.
