Experience

Binance.com | Fiat Deposit Withdraw

https://www.binance.com/en/fiat/deposit/EUR
A React-based project is a function within Binance.com that allow users to deposit or withdraw fiat, non-digital, traditional currencies like EUR and AUD. We have over 700,000 active users and a $5 billion trade volume each week, with a 99.5% order success rate.

My role as the front-end developer is to work with a team of project managers, product designers, back-end developers, third-party providers, quality assurance engineers, security team, and other teams to deliver a fast, secure, responsive, high-quality user interface for a user to place their transactions.

Verified users follow a three-step process to complete their transaction:

1. Users pick their preferred currency and payment method like a bank transfer.
2. We check if they met the requirement, balance, risk rating, and local government compliance, often providing additional forms for users to complete.
3. User confirms the transaction, and we communicate with our third-party provider to complete the transaction.

Flight and Hotel Booking Website

My role as a front-end lead developer was to work with my front-end team, product manager, designer, tech leads, and back-end developers to create this booking platform.

My responsibilities included delicate tasks for my team members, developments, mentoring junior members, and code reviews.
