About

As a Research and Development Engineer at MedAi, I specialize in leveraging Data Science and NLP within healthcare applications. My work centers on making digital health solutions more accessible, with particular expertise in human centerered computing. I played a key role in pioneering the first AI-powered digital health platform - AmarDoctor designed specifically for Bengali speakers, emphasizing accessibility and inclusivity. The platform incorporates advanced features including symptom assessment and clinical decision support capabilities. Beyond this, I manage MedAi's technical team, driving API design and cloud infrastructure development.

I'm driven by research that channels digital health, social computing, and AI (ML/NLP) to improve healthcare and wellbeing. My passion lies in creating human-centered technologies that deliver tangible, positive impact on people's lives.

Assistant Porgrammer

Janata Bank PLC.

I secured a position in a government bank through a rigorous and highly competitive selection process. However, I found that the role lacked the technical challenges I seek in my career. Consequently, I made a bold decision to leave the position in pursuit of opportunities that allow me to continuously learn and apply my technical skills to real-world problems.

Projects

Industrial Projects

Multilingual Symptom Checker & Clinical Decision Support System

This symptom checker module serves as an intelligent tool that facilitates the symptom selection process by suggesting relevant symptoms based on the input provided by the patient.
Once the patient has completed entering their symptoms, the module prompts additional questions tailored to the patient's responses (yes, no, or don't know). Subsequently, it presents provisional diagnoses along with pertinent specialization recommendations, guiding the patient towards the appropriate healthcare professional.


Medical Assistant Chatbot

The medical assistant chatbot discerns the user's mood and offers general illness options if the mood is suboptimal. It then tailors additional questions based on the identified intent of the chosen option and ultimately suggests whether the user should consult a physical health specialist or a mental health specialist.




Client Management System

Design and developed an API-based SaaS client management system that authorizes client access to our APIs. The system uses JWT authentication and allows clients to purchase services for flexible durations based on pre-defined packages.


Academic Projects

RFID Based Mobile Charging System (2017)

The system allows phone charging upon successful RFID identity validation. Presenting a programmed, valid white tag to the reader grants power access. An invalid tag or repeated switch toggling without validation will not enable charging.


Tic Tac Toe Game (2016)

This is an implementation of the classic Tic Tac Toe game using the Assembly programming language, specifically targeting the ASM 8086 microprocessor for both the game logic and its user interface. [GitHub]
