---------------------------------⭐️⭐️TOP STAR⭐️⭐️------------------------------------ ​Bridging the gap between rigorous Quality Assurance and cutting-edge Machine Learning, I am a technical specialist focused on the end-to-end lifecycle of intelligent systems. My expertise lies in architecting automated testing frameworks for AI-driven applications, specifically focusing on Large Language Models (LLMs), Voice AI, and real-time Computer Vision systems. With a background rooted in QA Engineering and a deep pivot into AI development, I ensure that complex, non-deterministic models meet production-grade standards for reliability, accuracy, and performance. ​Core Competencies ​1. AI & Machine Learning Integration ​I specialize in the deployment and validation of advanced neural networks. My technical stack is centered on Computer Vision, particularly the YOLO (You Only Look Once) ecosystem, including versions v8, v11, and the latest v26. I have successfully moved multiple CNN models from local development to production environments using Hugging Face and Gradio, ensuring that the underlying inference logic is both sound and scalable. ​2. Intelligent Automation & LLM Testing ​Testing LLMs and AI Bots requires a departure from traditional "pass/fail" logic. I implement evaluative frameworks that test for: ​Model Hallucination & Factuality: Validating LLM outputs against ground-truth data. ​Latency & Throughput: Optimizing real-time object detection and voice response times to ensure seamless user experiences. ​Edge Case Robustness: Using deliberate repetition and "overlearning" methodologies to identify failure points in bounding box logic, tracking IDs, and classification confidence scores. ​3. Advanced Technical Stack ​Programming & Frameworks: Expert-level proficiency in Python, OpenCV, and PyTorch. ​Infrastructure: Extensive experience in building and optimizing local AI workstations (utilizing high-VRAM NVIDIA hardware) for training custom datasets, reducing reliance on cloud-cost volatility. ​QA Automation: Designing robust CI/CD pipelines that integrate automated test suites with ML training workflows. ​Strategic Approach ​My methodology is defined by a commitment to technical mastery through depth. I don't just test software; I dissect the architecture behind it. Whether it is a vehicle-and-people counter or a security-focused weapon detection system, my approach involves a rigorous "bottom-up" validation process—ensuring the raw data input, the neural layers, and the final UI output are perfectly aligned. ​I thrive in high-intensity, focused environments where the goal is to solve "impossible" technical hurdles. By combining the precision of a Manual/Automated QA Specialist with the innovative mindset of an ML Developer, I deliver AI solutions that are not only functional but resilient. ​Key Project Highlights ​Medical Imaging AI: Developed and validated classification models for lung pathology and pneumonia with high-precision confusion matrix results. ​Real-Time Detection: Engineered tracking systems using YOLOv11 for complex environment monitoring, focusing on ID persistence and spatial accuracy. ​Production Deployment: Streamlined the pipeline for deploying custom-trained models to public-facing platforms, ensuring high availability and optimized inference.
