I have designed and developed "Calorie and Nutrients Counter (CNC)" App for calculating Calorie requirement, Daily Dietary, counting Calories and Nutrients (Carb, Protein, Fats, Sugar, Sodium and Cholesterol) in food to maintain healthy body or lose weight based on “Dietary Reference Intakes for Energy-2023” , “Dietary Guidelines for Americans 2020-2025” and US FoodData Central.I have designed and developed "AI Quiz and Image Viewer" App for testing or learning NLP, AI, ML algorithms, Data Science techniques, Deep Learning Neural Networks and their applications based on current trend in AI Industry. Image Viewer provides Core Image Filters: Vignette, SepiaTone, Monochrome, Sobel, Sharp Luminance, Thermal, Bloom and Canny Edge to observe images.I have designed and developed "Cyber Security Quiz (Useful)” App for testing or learning Cyber Security based on current trend in Cyber Security Industry. I worked on 5G heterogeneous wireless communications system architecture (small cells, cognitive radio networks, mobile femtocell, D2D and massive IoT) for resource optimization and higher QoS. I also worked on D2D communications in 4G-LTE assisted networks for Smart health monitoring system. I designed the Seamless IoT model for Smart City, Healthcare, Retails, Transportation in IBM's Node RED which upload sensory data to IoT Cloud servers and then send predictive information derived from ML/DL algorithm to end devices.I designed and used Machine Learning (ML) in 5G Wireless for forecasting on Small cell clustering, Massive MIMO, Macro cell UEs, and peak data rate in Python & Azure ML. ML is used in Cyber Security Analysis for Severity of Vulnerability using CVSS Score System. ML model is used in Heart Risk Prediction for CVD, Heart age and possibility of type of heart attack in Azure. ML is also used in NLP, CPS, Blockchains, Bankruptcy prediction and Quantum computing. ML also model Intelligent Cyber Physical system for Product Quality Predictions & Predictive maintenance. 12 years+ R&D experience in Wireless Communications (3G/4G/5G), Internet of things, Machine & Deep Learning, Cybersecurity, Cryptography & Networks Security, Smart City & Smart Health, Cyber physical system, Cloud Computing, NLP, DSP, Embedded , Neural Networks, Digital Image/Audio Processing, Networking , Computer vision, Digital Design, VHDL /FPGA, Robotics, Control system, Data Analytics, Quantum Computing, BlockchainsPh.D. dissertation on “Position Location and Tracking for Detection of Malicious Nodes by Maintaining Friendly nodes in MANET” , (2009-2011).
