Pet Nexus is a platform dedicated to veterinary practices and their clients, offering seamless appointment scheduling, client communication, and more. The project required maintaining and improving a legacy codebase while also migrating the infrastructure to modern container orchestration technologies.

Technologies Used:

Frontend: Angular, AngularJS, React

Backend: Node.js

Infrastructure: Kubernetes (K8s)

As a key member of the development team, I was responsible for maintaining and enhancing both the frontend and backend of the application. My primary tasks included:

1. Legacy Code Maintenance: Managing a complex mix of technologies, including AngularJS and newer versions of Angular and React. I ensured seamless integration of these frameworks, identifying and fixing critical bugs across the application.
2. Feature Development: In addition to bug fixing, I worked closely with the product team to design and implement new features that enhanced the user experience, focusing on performance optimization, UI/UX improvements, and extending existing functionalities.
3. Migration to Kubernetes: I took ownership of the task of transitioning the application to Kubernetes. This involved:
4. Containerizing the Node.js backend and deploying it within Kubernetes clusters.
5. Managing Kubernetes configurations for scalable deployment and rolling updates, ensuring high availability and reliability.
6. Setting up CI/CD pipelines to automate deployments and facilitate a smoother development workflow.

Achievements:

1. Successfully stabilized and modernized the legacy codebase.
2. Improved application performance and user experience through feature updates and bug fixes.
3. Enabled seamless deployment and scaling through Kubernetes migration, reducing downtime and improving overall application resilience.

Challenges Overcome:

1. Managing a codebase that used multiple frontend frameworks, ensuring that updates did not disrupt existing functionality.
2. Overcoming technical debt and ensuring that new features aligned with legacy systems.
3. Implementing Kubernetes for scalability while maintaining a smooth development workflow.

This project honed my skills in maintaining and modernizing legacy systems while leveraging cutting-edge infrastructure technologies like Kubernetes. It provided valuable experience in managing a complex codebase, working across multiple frontend technologies, and ensuring smooth application performance through container orchestration.
