Mintyn Website

https://mintyn.com/
Mintyn is a website that acts as the face of Mintyn Online Bank.

It showcases and advertises various banking and payment services offered by Mintyn Online Bank, including personal and business accounts, mutual fund investments, money transfers, airtime and data top-ups, utility bill payments, and savings.

It was built with Next.js, jQuery, JavaScript, Bootstrap, styled-components, and Sass.

My main contribution was rebuilding the website, which is the face of the company and requires a pixel-perfect design.

Firstly, I reviewed the design with the product team to make sure the design was pixel-perfect and had clearer concepts about the design. I defined the design elements and templates that are globally available, which resulted in re-useable components such as buttons, typography, spacing, and so on. I architected the layout and the whole code structure and developed the website with the same characteristics as the design.

It provides various banking and payment services, which include personal and business accounts, mutual fund investments, money transfers, airtime and data top-ups, utility bill payments, and savings.

It was built with React, Redux, JavaScript, Bootstrap, styled components, Sass, and Chart.js.

My main contribution was building the utility bill payments and savings features by architecting the layout, implementing the features, refactoring the onboarding process and subsequent features, and writing a test for each implementation.

Blusalt Customer Portal

https://app.blusalt.net/
A Vue-based application for identity verification and payments. As the front-end engineer, I was brought in to stabilize a non-functioning and unsellable merchant portal and its admin. It was a daunting task for me as I did not have much experience with Vue at the time. However, I stabilized the merchant portal and its admin and added more features. The project was successful and is currently used by a lot of merchants.

Meritrade

A React-based stock trading web application to trade stocks in Nigeria. I single-handedly built the application from start to finish using React and Apollo graphQL because of its real-time data transmission.

I was tasked with building the whole website, which is the face of the company and requires a pixel-perfect design.

Firstly, I reviewed the design with the product team to ensure it was pixel-perfect and had clearer concepts about the design. I defined the design elements and templates that are globally available, which resulted in re-useable components such as buttons, typography, spacing, and so on. I architected the layout and the whole code structure and developed the website with the same characteristics as the design.
