Al Quran - Bangla

A feature-rich Quran app in Bangla with Arabic verses and Bangla translation, a daily featured verse, prayer time schedule, Qibla compass, Tasbih counter, memorization tracker, dua collection, and the 99 Names of Allah.

Challenge
Bangla readers usually need several apps — one for the Quran, one for prayer times, another for tasbih and duas — and most are Arabic- or English-first.
Result
One light Bangla app that holds the Arabic text with translation and the daily essentials around it — published and ready to install.

Enterprise / ERPSchool ERP

PrioEdu — School Management System

A complete school management system — admissions, students, staff, attendance, exams, fees, accounts, hostel, transport, library and inventory — with a public school website and a bilingual admin dashboard.

Challenge
Admissions, attendance, exams, fees and accounts usually live in separate registers and spreadsheets, so nothing reconciles and reports take days.
Result
One bilingual system for the whole school — from admission to results and accounts — with a public website and multi-branch support built in.

Family Budget Tracker

A bilingual family budget tracker built for two users to log shared income and expenses in real time, backed by Firebase Auth and Firestore.

Challenge
Couples track shared spending in chats and notebooks, and nobody sees the full picture.
Result
A shared Bangla budget where both partners log income and expenses and see updates in real time.

Nirman Bazar — Construction Materials Marketplace

A full marketplace for construction materials (brick, sand, cement, rod, stone) with cart, checkout, bulk quotations, and an admin dashboard for inventory, orders, and delivery.

Challenge
Buying bricks, sand, cement and rod in bulk is slow: prices, stock and delivery are hard to compare.
Result
One storefront for ordering, bulk quotations and order tracking, plus an admin dashboard to run inventory and delivery.

IT Accessories E-commerce Platform

An IT accessories e-commerce platform with OTP-based login, wishlist, product reviews, quotation requests, and an admin panel for stock and payment verification.

Challenge
Shoppers compare specs slowly and shops juggle stock, payments and returns by hand.
Result

API Documentation Admin Panel screenshot 1
Enterprise / ERPInternal Tool

API Documentation Admin Panel

An internal admin tool for organizing and documenting API endpoints by menu and submenu, with automatic tracking of newly added and recently updated APIs.

Challenge
API documentation scatters across wikis and chats, and nobody can tell what changed.
Result
One browsable portal organised by menu and sub-menu that flags newly added and recently updated endpoints.

Enterprise / ERPDevOps Tool

Deployment Manager

A deployment automation dashboard that manages servers and projects and streams live build/deployment logs to the browser over WebSocket.

Challenge
Deploying means SSH sessions and guesswork about whether a release really went through.
Result
A dashboard that manages servers and projects and streams live deployment logs straight to the browser.

Enterprise / ERPDevOps Tool

Service Builder — Git Auto Build Tool

A DevOps tool that clones a Git repository, runs the Maven build automatically, and tracks every build's status and logs behind authenticated access.

Challenge
Every service build repeats the same clone, pull and Maven steps by hand.
Result
Pick a service and it clones or updates the repository, builds it with Maven and records the status of each action.

Spring Boot Manager (Desktop Tray App)

A Windows desktop tray app for starting, stopping, and monitoring local Spring Boot JAR services without touching the terminal.

    Flutter · Spring Boot · Next.js

    Built from a love of code and shaped by real needs — Priokod is a collection of apps, web platforms and enterprise software by Sazzad Mahmud.

    From a Quran app in Bangla to ERP, school management and a live deployment dashboard — every project aims to make work easier through technology.

    With Flutter, Spring Boot and Next.js, those ideas become usable software. A smooth experience, dependable behaviour and care in every detail — that is the belief behind each project.

    How I build

    The thinking behind the code

    Start with a real problem

    Every system began as something tedious to do by hand — keeping records, running deployments, documenting APIs.

    Clean, typed code

    Layered Spring Boot services and TypeScript on the web keep things easy to read and easy to change.

    End to end

    From the database and API all the way to the screen and the deployment.
