TalendIT

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.

More about this engagement

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.

nDevers

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.

More about this engagement

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.
