Rpa Developer
ISA INTERCOLOMBIA
2022 - 2022
I successfully completed my internship at ISA INTERCOLOMBIA as an Rpa Developer. During my time there, I analyzed potential processes for automation, developed bots, and created comprehensive documentation and usage guides. Additionally, I enhanced existing processes and built no-code applications using Power Apps.
One of the standout bots I developed was designed to read records from Excel and create a corresponding entry in SAP for each record. At the end of the process, the bot generated a summary report detailing the data that was successfully processed and any records that could not be processed.
Personal Mentor
University Institution of Envigado
2017 - 2022
As a CCNA 1 instructor, I taught networking fundamentals, including OSI and TCP/IP models, IP addressing, and basic configuration of Cisco devices. I guided students in using CLI commands to configure routers and switches, as well as troubleshooting basic network issues. We also covered network security and services like DHCP and DNS.
As a Java instructor, I taught the fundamentals of the language, including basic syntax, object-oriented programming, and exception handling. I guided students in building simple applications, from designing classes to implementing control structures and methods. We also covered topics like collections, file handling, and basic concurrency concepts.
As a Python instructor, I taught the basic concepts of the language, including syntax, data types, and control structures. I guided students in creating simple scripts and more complex applications, covering topics like object-oriented programming, file handling, and modules. We also explored the use of popular libraries for data processing and automation.

Repository Issue Management
Description:
The application allows users to manage GitHub issues on the Angular repository, including viewing and filtering issues by status (open, closed, all). The app is structured into various components and services that facilitate interaction with the GitHub API and present the data in the user interface, providing an intuitive and efficient experience for managing issues in the repository.
Standalone Components
The application leverages standalone components, which are self-contained and independent, allowing for better modularity and reusability. This approach simplifies the app structure by reducing the need for shared modules, making it easier to develop, maintain, and test individual components.
Dependency Injection
The app uses dependency injection to provide services and resources efficiently across components. This design pattern enables loose coupling between components and services, making the application more flexible, scalable, and easier to test by allowing dependencies to be injected where needed.
TanStack Query
The application integrates TanStack Query to manage data fetching, caching, and synchronization with the GitHub API. This powerful library simplifies handling asynchronous data, reduces boilerplate code, and improves the app's performance by caching data and updating it efficiently in response to changes.
