Backend Development for Step In App

Cesar

Cesar Ocampo

I played a key role in creating and integrating the backend services that underpinned the main features of the application while I was an apprentice full-stack developer at Step In App. Creating scalable backend architectures, putting Domain-Driven Design into practice, and making sure frontend components integrated seamlessly were all part of my duties.

๐Ÿงฑ Responsibilities:

๐ŸŸ  Backend Development: Utilized Node.js and PHP to build robust backend services, ensuring efficient data processing and management.
๐ŸŸ  Database Management: Managed MySQL databases to support authentication mechanisms and maintain data consistency across the application.
๐ŸŸ  API Integration: Implemented RESTful APIs to facilitate communication between the frontend and backend, ensuring smooth data flow and user interactions.
๐ŸŸ  Domain-Driven Design (DDD): Applied DDD principles to model complex business domains, leading to a more maintainable and scalable codebase.
๐ŸŸ  Security Implementation: Ensured secure data handling by implementing validation checks and adhering to best practices in API consumption.
๐ŸŸ  Version Control and Collaboration: Utilized Git and GitHub for version control, enabling effective collaboration with the development team.

๐ŸŒ Tech Stack:

Backend. Node.js\next.js
Database MySQL
Designed and consumed REST APIs following microservices architecture principles, using JSON for inter-service communication.
Domain-Driven Design (DDD)
DevOps Git
GitHub

๐Ÿ’ก Key Features:

๐Ÿ”’ Secure Authentication: Implemented secure user authentication mechanisms, ensuring data privacy and integrity.
๐Ÿ”„ Efficient Data Handling: Optimized data retrieval and storage processes, enhancing application performance.
๐Ÿ“ˆ Scalable Architecture: Designed backend systems with scalability in mind, accommodating growing user demands.
๐Ÿงฉ Modular Design: Structured codebase into modules based on DDD, facilitating easier maintenance and feature additions

โœ… Outcome

The backend systems developed contributed to a robust and scalable application infrastructure for Step In App, enhancing user experience through efficient data handling and secure operations. The application of Domain-Driven Design principles ensured that the codebase remained maintainable and adaptable to evolving business requirements.
