Dev Spotlight: Decagon Trainee Builds All-in-One Expense Tracking App

As part of our software engineering training at Decagon, developers are required to build a functional product, typically a web-based software or a mobile app.

Elujoba Folorunso Olawale,going by Wale, a Python developer from Squad 7, developed an application that keeps track of users’ finances. Named FinTrak, the app lets users conveniently track their monthly income and expenses and prepare a budget.

Here are some exciting highlights about FinTrak:

The FinTrak Web Application: A Brief Overview

The Inspiration Behind FinTrak

Wale was curious to find out how he spends his income on a monthly basis. This inquisitiveness led to the creation of FinTrak.

Since the app made this possible for him, he wants to help others understand their expenses more, and identify leaking points.

Challenges Encountered and Solutions

Building a fully-functional software application from start to finish is not the easiest thing to do, with a couple of blockers on the backend and frontend.

While building with scalability and efficiency in mind, these challenges can be overwhelming.

For Folorunso, the possibilities and potential of the FinTrak app made the process worthwhile. The knowledge acquired during the Decagon training was a major player.

More so, Decagon provides a community of mentors and peer leaders, who provided inputs in various forms.
