Experience
ETHvil Bank (2021)

I built it using Solidity, Hardhat, Ethers.js, Next.js, TypeScript, React, TailwindCSS, and Storybook.
Notes:
• 100% test coverage on the smart contract.
• Deployed only on Ropsten test network, for now.
• Source code published on GitHub.

Hangul Games (2021)
Developed a website to help me practice reading Korean, which I am currently learning.
Users can read a provided sentence and check their pronunciation by listening to an audio of the sentence generated using the Azure Speech service. It is built as a MERN stack web application and hosted on Azure as a single container web application.

SWLC PAL (2021)
This web application is a cards manager tool and decks database for the Summoners War: Lost Centuria game. It is built with Next.js for better SEO with server-side rendering. The app uses HTML canvas a lot, both in browser (live cards rendering) and server-side (full user's collection image generation).
It features a custom-made discord authentication module, allowing better privacy as it doesn't require knowing users' emails. The application is hosted on Azure as a multi-container web application—one for Nginx, one for the web app itself, and one for long-running tasks such as image generation.

Webmail4dev (2017)
https://github.com/ArnaultNouvel/webmail4devWebmail4dev is a local SMTP server with no auth and a web server that displays all emails received by the SMTP server, meant for testing environments.
It is meant to be used as a web-based fake mail server for testing applications that send emails, such as SharePoint. Using such a mail server ensures that emails are not sent to real mailboxes while making it easy for test users to read all outgoing emails with their web browser.
