Multiversal Software Ltd. · Aug 2022 - Oct 2022 · Uttara, Dhaka, Bangladesh
Built and maintained UI components for a telemedicine platform using React.js, JavaScript, HTML5, and CSS3, improving user experience across devices. Debugged and optimized front-end code, reducing page load time and enhancing performance stability.
Codez Info Tech. · May 2021 - Nov 2021 · North Badda, Dhaka, Bangladesh
Developed and maintained web applications with PHP and JavaScript. Analyzed client needs and developed appropriate functionality. Created and executed test scenarios to ensure quality deliverables.
Freelance Developer · Mar 2024 - Mar 2024
Built the shared API foundation for an MCQ learning platform, with versioned Express routes, request protection, email error notifications, and deployment configuration. Learning-domain operations remain scaffold implementations.
Organized questions, exams, courses, enrolment, and results into versioned Express modules for an MCQ learning platform. Centralized controller wrappers, response formatting, and error handling to give new features a consistent API structure. Added Helmet security headers, request limits, timeouts, and rate limiting at the application boundary. Included Nodemailer error notifications and Docker/PM2 deployment configuration. The reviewed implementation establishes API infrastructure; persisted learning workflows, exam execution, and result storage remain incomplete.
Freelance Developer · Oct 2023 - Nov 2023
Built school information interfaces, Google Drive admission-document storage, and survey APIs with separate definitions, templates, and completed records. Co-developed a PHP/MariaDB catalog and administration project.
Built Next.js and React school pages for admissions, notices, routines, results, staff, and galleries, with responsive navigation, Swiper galleries, and a Google Maps integration. The frontend uses local sample content and an in-memory admin demonstration. In the school backend, implemented Google Drive file handling and stored admission-document identifiers and links in MongoDB. Separated controllers, persistence services, and Joi input validation. Built Mongoose survey CRUD services, keeping survey definitions, reusable templates, and completed school/location records separate. Co-developed TechnoFire's PHP, MySQLi, and MariaDB catalog and administration codebase with Abid Hasan Piash; individual ownership of its features is not established. These repositories document prototypes and implementation scope, not verified production deployment.
Freelance Developer · Apr 2022 - Aug 2022
Built React inventory workflows with Firebase Authentication, stock-update and delivery requests, and user-specific item views. Implemented a separate Express/MongoDB inventory API for products and supporting business records.
Built inventory browsing and item-management interfaces with React, React Router, and Tailwind CSS. Integrated Firebase Authentication, shared sign-in helpers, and an email/token request flow, using Axios for stock updates, delivery actions, and user-specific item requests. POSDash depends on its own companion server; it is not the client for the separately documented inventory API. In that Express and MongoDB backend, implemented product reads, creates, updates, and deletes, with pharmacy and non-pharmacy resource routes. Organized orders, returns, suppliers, customers, and employees into dedicated endpoints. The reviewed legacy source contains incomplete and miswired routes, so the portfolio describes implemented components without claiming complete end-to-end operation.
Versioned, provenance-rich Bangladesh location registry with census, postal, facility, ward, and infrastructure data from government-published sources.
