Projects

AgriStore — Full-stack commerce platform

2025 · Spring Boot · Thymeleaf · MySQL · AWS

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

2024 · Flask · Groq · Llama 3 Vision · Whisper · ElevenLabs

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.
