E-Book Digital Storefront with Stripe Payments

A full stack digital product store with separate customer and admin dashboards for products, orders, and payments, backed by a versioned Laravel REST API with Sanctum token auth.

• Laravel
• Next.js
• Sanctum
• Stripe Cashier
• AWS S3
• MySQL
• React Hook Form

• —Integrated Stripe Checkout via Laravel Cashier and fulfilled orders from webhooks verifying payment status and stored session ID before marking payments paid and granting product access in one database transaction.
• —Calculated order totals from database prices rather than client input to prevent price tampering.
• —Delivered files through AWS S3 pre-signed URLs letting admins upload directly from the browser and customers download purchased files via links that expire after minutes.
• —Used Next.js App Router server actions with HTTP-only cookies for token storage and kept business logic in a service layer with form request validation and API resources.

ChatN — Group Chat & Video Conferencing

A full-stack real-time communication app for multi-user group chat and video conferencing, split into three repos for production-style architecture.

• Laravel
• Next.js
• Docker
• Caddy
• Reverb
• LiveKit
• TanStack Query

• —Used LiveKit (SFU architecture) rather than P2P mesh because this approach saves on client bandwidth and guarantees the stability of video streams.
• —Handled real-time messaging using Laravel Reverb (WebSockets) and optimized chat history loading with cursor pagination for smooth infinite scrolling.
• —Managed the server and client states using TanStack Query and Zustand, respectively.
• —Containerized the whole stack via Docker and set up Caddy as the reverse proxy with local SSL and nip.io routing for testing purposes within the whole local network.

Custom PHP MVC Framework

A custom lightweight MVC framework written from scratch to gain thorough knowledge about modern frameworks' inner workings and the use of design patterns and OOP concepts.

• PHP (OOP)
• PDO
• MySQL
• Composer

• —Implemented an IoC / Service Container using PHP's ReflectionClass to support automatic Dependency Injection (DI) and method type-hinting, inspired by Laravel.
• —Developed my own ORM-based database layer that uses PDO to perform secure and object-oriented database operations and prevent SQL injections in MySQL.
• —Implemented modular core components including PSR-4 autoloading, custom routing, environment configuration (.env loader), and base Model-View-Controller classes.

Real-Time Communication (RTC) Proof of Concept

A peer-to-peer real-time communication proof of concept built to deeply study browser-level WebRTC internals and bidirectional signaling protocols.

• Next.js
• WebRTC API
• Pusher
• STUN

• —Implemented Pusher Channels for WebSocket signaling, handling real-time peer discovery, channel subscriptions, and custom event dispatching.
• —Integrated the native browser WebRTC API from scratch to manage peer connection handshakes, including SDP Offer/Answer exchange, ICE candidate gathering, and STUN server negotiation.

User Management System

A simple user management web application featuring complete CRUD operations and user authentication.

• PHP
• MySQL
• PDO
• Alpine.js
• HTML/CSS

• —Designed the back-end with clean architecture / SOLID design pattern to separate the business logic from the database and provide a modular RESTful API using PHP.
• —Implemented raw PDO prepared statements without an ORM to master safe manual SQL querying and prevent SQL injection vulnerabilities.
• —Designed a responsive front-end application with HTML/CSS and Alpine.js.

Ricemill — Transaction Web App

A Laravel application managing transaction workflows for a rice mill business — server-rendered pages, Eloquent data modeling, validation, and maintainable domain logic.

• Laravel
• PHP
• Blade
• MySQL

• —My most recent build — modeling real business transactions with Laravel conventions.
