Built from Scratch
Business ERP System
ERP
A complete business ERP system for inventory, sales, purchases, accounting, reporting, warehouse management, and role-based operations with transaction-safe financial and stock workflows.
A full-stack, multi-tenant website and content management platform that powers five live school and college websites from a single codebase, each with its own isolated database and admin dashboard.
BTEB is a full-stack, multi-tenant content management platform built for educational institutions in Bangladesh, including colleges affiliated with the Bangladesh Technical Education Board (BTEB) as well as general secondary schools. A single React and Express codebase serves five distinct, independently branded institution websites, each resolved by domain and backed by its own isolated MongoDB database.
The backend uses a custom domain-resolution middleware that reads an 'x-college-domain' request header, maps it to the correct institution database, and attaches the connection to every API request — so one deployment can safely serve completely separate schools without any data crossing over.
Each institution gets a full public-facing website (notices, results, class routines, staff and student directories, galleries, and more) plus a JWT-secured admin dashboard with over fifteen CRUD modules, letting non-technical school staff manage every section of the site themselves — from publishing admission notices to uploading exam results and updating the photo gallery.
