Major accomplishments include:

* Improving the UI and building the necessary features in 3.5 months in order to launch the v1.0 in time for the Organization Global Summit, in May 2019
* Improving infrastructure code to support Server Side Rendering of the Vue App and optimizations of bundle size for overall faster client time-to-interactive and server responsive times.
* Mentor students participating in the Google Summer of Code program. Mentored student successfully delivered a new version of the CC License Chooser: https://chooser-beta.creativecommons.org/. One of the students ended up being hired by the organization a few months after the program ended.

Lead developer responsible for the frontend of the purchase system.
- Initially responsible for delivering the v1 of the rewrite of the purchase systems in React, migrating away from a system using legacy Django templates.
- I worked alongside the backend team to successfully deliver the changes required to enable the USA expansion of the company.
- Delivered the UI changes to the purchase systems which were required to adapt it in time to the new GDPR regulations.
- I managed work prioritisation of new features requested by the product management team along with tech-debt backlog that would ensure code quality and maintainability, while keeping the total size of the bundle delivered to browsers small (< 200KB gzipped).
- I was involved in helping HR with hiring new people for the company, doing both personal and technical interviews. Also helped defining hiring requirements and technical interview questions for both Frontend Engineer and UX/UI Designer job openings.

I focus primarily on the front-end side of an application created for a large oil and gas company in Brazil. We use Facebook React.JS framework for building a Single-Page-Application, following the Flux architecture, and using immutable data structures in our data model for better handling of concurrent events. I built the charting solution for data visualization using SVG (Scalable Vector Graphics). The biggest challenge was optimizing rendering and heavy calculations on large datasets. After optimizations were introduced, rendering of charts was two to three times faster, depending on the size of input data. I also developed a diff utility for Immutable.JS data structures used to handle updates in the data model. The source code is available on Github (https://github.com/intelie/immutable-js-diff).
