Refactored an application due to issues with performance and looming bottlenecks. Developed new features in the app, e.g., Google Maps, Apple Pay/Google Pay, location- based results, or opening a hotel room using NFC. Reworked a wallet into a React Native solution instead of using separate iOS (Objective-C)and Android (Java) versions. Implemented new check-in solutions for restaurants and hotels using React Native. Created tooling necessary to easily add new assets and configure them so that a new client’s new application could be easily created without developer input. Developed native libraries for key door unlocking for hotels and added React Native bindings for them to be used within an application. Added CI/CD process deployment with AppCenter instead of the manual building that was consuming much developer time. QA can build a new version on demand and set version code and their own. Deployed apps for release on both the App Store and Google Play Store. Set up deployment for web projects (wallets) with CI/CD on Bitbucket Pipelines.

Introduced necessary back-end functions within Firebase cloud functions, e.g., analyzing breath and facial recognition. Implemented background tasks in the application for checking user activities walking/driving) in intervals/if there is a request for the user to take a test. Added a scheduling system by introducing cron jobs with Firebase cloud functions. Included a breath analyzer in the application and created React Native bindings for native SDKs. Introduced a face recognition API to be sure that the user, in fact, is the one that is supposed to use it (due to legal reasons).

Resolved before-release problems with a React Native application; also introduced Firebase tracking and performance tools. Improved code quality and bottlenecks in the application and wrote down potential issues that could occur in the future due to new planned features. Fixed performance and flow issues in an application regarding polls and login system.

Took a leading role in introducing new technologies within new projects and existing ones. Created new applications from proof of concept to regular apps and made decisions regarding tooling in the front end. Improved the possibility of using .NET Core within the company by introducing improvements to CI/CD.Analyzed client requirements and maintained multiple production applications. Created the first mobile application within the whole company, using React Native, which was really well received by its customers. Created pipelines for CI/CD for mobile development from scratch. Helped colleagues with complicated or performance issues in a front-end environment.
