Projects
AgriStore — Full-stack commerce platform
E-commerce platform designed around farmers, with role-based authentication, product management, and automated PDF invoices. Deployed on AWS using Elastic Beanstalk, EC2, S3, and RDS, with SQL query tuning as the dataset grew.
DoctorG — Multimodal AI assistant
Combines voice conversation, image analysis, and spoken responses. Whisper transcribes speech, Llama 3 Vision analyses images through Groq, and ElevenLabs returns the reply as audio — connected by Flask into a low-latency loop.
FaceMeet — Authenticated video conferencing
Video conferencing with facial-recognition authentication. The backend verifies the participant, establishes a secure session, and connects the call through VideoSDK.
Research
Comparative Study of YOLOv8, Faster R-CNN & SSD in Traffic Sign Detection
Benchmarks detection approaches for GPS feedback, monitoring systems, and autonomous-driving deployment.
Login Confirmation Mechanism for Meeting Platforms
Examines facial recognition for participant authentication: accuracy, latency, and robustness in real-world conditions.
