About Me

As a Software Engineer at Alphatec Spine, I specialize in developing scalable .NET-based microservices using ASP.NET Core and .NET 8.0, while driving innovation in applied AI through deep learning and computer vision. I have expertise in training, deploying, and optimizing various CV models using PyTorch and OpenCV, including object detection models like YOLOv8, for production-grade computer vision solutions. My work emphasizes clean architecture principles to support robust and efficient systems.

I am also the Founder and Software Engineer of NexMenus, where I lead the development of a multi-tenant SaaS platform for restaurant menu management. By leveraging Django, PostgreSQL, and AWS S3, I create mobile-first, localized applications with secure subscription workflows through Stripe integration.

My technical foundation includes comprehensive education in Java programming from UC San Diego Extension, along with nearly 6 years of experience in software development, automation, and cloud infrastructure.

FoodPhotoEnhancer Detection

FoodPhotoEnhancer - AI Food Photography Enhancement

(Private Repository - App in Development) Developed an AI-powered food photography enhancement system that automatically detects and enhances the main food subject in images. Engineered a multi-factor weighted scoring algorithm combining normalized mask area, proximity to image center (exponential distance decay), and depth prominence to identify the primary dish. Implemented adaptive iterative refinement with exponential threshold decay to expand subject boundaries and capture garnishes. Integrated Grounding DINO for text-prompted detection and SAM for pixel-precise segmentation with LRU caching for optimized inference.
