Hi, I'm Mercy Njuguna,

and I'm a Full-Stack Software Engineer.

With expertise in Python (Flask), JavaScript (React, Express, and Node.js), C#, Angular, PHP (Laravel), and the .NET Framework, I specialize in delivering robust, scalable solutions.

About Me

Logo

I am a certified full-stack software engineer with over 2 years of professional experience developing robust web applications, delivering exceptional user experiences, and creating intuitive front-end designs.

I completed the ALX Africa 15-month Software Engineering Nano degree in March 2024, where intensive project-based training strengthened my technical skills and problem-solving abilities across the software development lifecycle.

Additionally, I graduated with a Bachelors in Business and Information Technology from Jomo Kenyatta University of Agriculture & Technology in 2016. This program provided me with a diverse skill set encompassing business development, marketing, finance, and IT.

With over 2 years of professional experience in business development within technology companies, I transitioned into software engineering driven by a passion for developing customer-centric software solutions that address real-world problems.

DentalEasePro

Visit DentalEasePro

This is a fully functional web application that automates the daily tasks of a dental supplier. I contributed to both the frontend and backend development, delivering an end-to-end solution that streamlines business operations and improves efficiency.

Since the site contains personal data, login is required.

Technology Stack: Python (Flask), MySQL, HTML, CSS, JavaScript

Functionalities:

  • Customer and Product Management: Allows the dental supplier to easily access, add, and remove clients and products, enhancing operational efficiency. The web app replaces traditional record-keeping methods with a modern, efficient solution for a smooth user experience.
  • Invoice Creation: Enables the supplier to generate invoices by selecting a customer, specifying products and quantities, setting a due date, and recording payments. A warning is triggered if the selected quantity exceeds available stock, ensuring accuracy in both invoicing and inventory management.
  • Generate Statements: Allows the supplier to review all pending invoices, filter by customer ID or name, and generate statements with ease by clicking the "Generate Statement" button.

This application has significantly impacted the supplier's business.
