Building Behind the Scenes

I am a Software Developer specialized in engineering robust backend architectures, custom automations, and enterprise-grade ERP systems. With high proficiency in Python, Flask, PL/SQL, and Oracle EBS databases, I design software that transforms manual, paper-driven processes into automated pipelines.

Beyond logic and database queries, I am a creative explorer. As the former President of the NSTU Photography Club, I spend my spare time finding patterns through lenses. I believe software engineering and photography share the same heart: capturing and structuring complex realities into beautiful, clean frameworks.

Full Stack Web Application

NSTU Transit

A centralized web-based transit and bus routing application customized for Noakhali Science and Technology University (NSTU) to manage university fleets, driver shifts, student ticketing metrics, and real-time route statuses.

The Challenge: Manual planning, driver reporting delays, and zero transparency for students trying to track physical university transit routes.
The Solution: Built a relational database mapping coordinates to specific transit numbers, displaying schedule tables and vehicle availability in real time.

Industrial Automation & Database

Energy Meter Management System

A specialized consumer dashboard built with Flask designed to let end-users log and monitor monthly electrical power consumption, download bill generation statements, process invoice payments, and report infrastructure anomalies.

The Challenge: High database response times due to poorly structured transaction tables log entries.
The Solution: Structured indexes, set up clean relational schemas, and integrated chart dashboards showing monthly kilowatt-hour consumption distributions.

Artificial Intelligence Utility

AI Chat Log Summarizer

A web application designed to take raw chat conversation texts and generate concise, structured summaries identifying main discussion themes, action items, sentiment statuses, and chronological key points.

The Challenge: High noise ratio in chat transcripts (greetings, off-topic notes) making manual scanning inefficient.
The Solution: Implemented prompt engineering algorithms that isolate message threads and format actionable outcomes cleanly.
