 Android Software Engineer, Appetize

Jan-2020 - Jan-2021
Description: I developed features on a sales platform that facilitates transactions for clients using dedicated hardware or attached POS systems. The platform enables card transactions from different payment providers and serves as a standalone kiosk or mobile platform. The system is widely used across various industries, including entertainment venues like Disneyland and Dodger Stadium, as well as companies like Atrium Aquarium, Venuetize, and Skidata. The platform provides a seamless payment experience for customers and enables businesses to efficiently process transactions, making it an essential tool for enhancing sales input
Responsibilities: 

• Worked through the development of a module for the Android application that integrated different payment providers, enabling clients to securely and easily process payments and increase revenue

• Wrote clean, maintainable, and testable code using Kotlin and Android SDK, following SOLID principles and design patterns

• Collaborated closely with clients to understand their business requirements and integrate their payment services into the application

• Conducted spikes and proofs-of-concept for different clients, using agile methodology and rapid prototyping, to validate technical feasibility and identify potential issues and solutions

• Actively conducted code reviews, using tools such as GitLab and SonarQube, to ensure code quality, consistency, and maintainability

• Integrated new clients into the Android platform, using RESTful APIs and OAuth2 authentication, to enable seamless and secure payment processing

• Wrote unit tests using JUnit and Mockito, to ensure code correctness and prevent regressions

• Presented features and updates to clients and stakeholders, using tools such as PowerPoint and Confluence, to ensure transparency and alignment

• Successfully proposed and implemented a POC:  When the pandemic kicked in, the users submitting orders on the Elo devices were reluctant to use the Elo tablet anymore. It was a severe problem, and I paired with a colleague to develop a remote control for the Android application. In short, I designed a server(Node.js) and managed the connection to the application through sockets. The use case was simple: the user scanned a QR code to establish a session with the server. The server sent back a web page that represented a virtual pad used to move an overlayed icon in the Android application. All the coordinates were proxied through the server back to the application, where we updated the cursor's position and managed the click events. The proof of concept was a success and accepted by the client and sent for further implementation to the backend team
