I build end-to-end web applications, event-driven microservices, and AI-integrated systems using Java, Spring Boot, React, Python, Kafka, Redis, and MongoDB.

At Harit Vikas Technologies, I independently owned data analysis for a client project, building a Python dashboard across three datasets. I also developed Bengali-to-English preprocessing and automated EDA workflows that delivered structured stakeholder reports.

My projects include RideShare, an Uber-style platform with Spring Boot microservices, Redis geospatial driver search, Kafka-based events, and Dockerized services. I also built Talkative, a real-time chat application with WebSockets, JWT and OAuth2 authentication, and a Python moderation microservice.

Through AgroVeda, I combined Flask, React, MongoDB, machine learning, and ESP32 IoT sensors to support data-oriented farming decisions. My plant disease model achieved 85% accuracy, while crop recommendation and agricultural prediction features reached up to 95% accuracy.
