I have helped to guide, help and mentor new devs to give them a solid base knowledge to be able to contribute to the codebase. I am very supportive with them with anything they need, technical questions, feedback, 1:1, etc As a Tech Lead, I am very involved on the product, from the planning of new features, to the estimation, architecture and implementation. Also, I am always thinking about things to improve on the app and workflows inside the startup.

I put in place good practices in the codebase like conventional commits, PR conventions and Microsoft Teams bots to notify developers about a new commit, comment or merge

Also, I defined and executed a Devops strategy for the Mobile Web app, where every time we commit to the Dev branch (through PR's) new builds (android, iOS and web) are created on the BitBucket pipeline, and once the builds are finished (either succed or failed) I notify the testers in Microsoft Teams with a custom web-hook app I created.

I was a key piece in my team and in the whole company due to my expertise in React, React Native, Javascript and good practices. practices. I had the opportunity to plan, architect and create apps from scratch.

We used React Hooks for all the components and Screens, the project was pretty well structured, the code was very clean, organized and abstracted to be re-usable in many parts of the app. We also had models with types (using Flow) for each part of the data inside the app.

Other interesting feature is the addition of mocking api functionality in the mobile side - in that way we continue with the work while the backend team was finishing the endpoints, and at the time they finish, is just to comment basically a line of code and everything will work as expected with the real API!
