During my tenure as a React Developer, I spearheaded several significant achievements that played a pivotal role in elevating a transformative platform within the oil industry.Platform Evolution: Successfully led the development efforts to upgrade the platform from version —.1 to version '.1. This involved implementing crucial enhancements and features, contributing to the overall advancement of the application's capabilities and performance. Innovative Data Manipulation: Engineered an Excel-like table functionality that streamlined data management within the platform. This feature empowered users to manipulate and analyze data with ease, significantly improving workflow efficiency. Real-Time Map Data Layers: Introduced a cutting-edge feature enabling real-time manipulation of map data layers. This innovation allowed users to dynamically interact with geographic information, fostering a more responsive and insightful user experience. Optimized Continuous Integration (CI): Played a key role in optimizing the Continuous Integration (CI) pipeline, reducing its total run time from over 01 minutes to just under 5 minutes. This optimization significantly enhanced the development workflow, fostering faster and more efficient iteration cycles.

During my time at Whitespectre I was in charge of creating a React application that was used by some of the biggest companies in the world, Santander Bank and Coca-Cola to name a few. I worked in a very agile environment and grew my experience immensely in terms of application testing as I was the only Front end developer on that project. Biggest challenge was to make the page behave like a carousel that would fit height wise on every PC and optimize to to work with a lot of Lottie animations which all were CPU intensive due to the nature of properties they were affecting.

While working at Oykos I was in charge of all technical aspects of the company. Working as Full Stack dev as well as System admin, I was involved in every project from the beginning and planning to deployment, testing, etc.During this time, the most complicated project was the task management/planning platform. We developed a completely custom, without any plugins, task-based system with the calendar and real-time notifications and real-time updates, as well as a cloud-like file management system that had all the features modern cloud providers offer. There were a couple of complicated features that needed to be implemented, most notably the drag-and-drop upload folder functionality. I worked both as a Back end and Front end developer. Due to the big percentage of Junior developers that worked in this company, I had to develop devkit that enforced certain rules and best practices, but would also greatly improve development speed, as we had completely customizable components that could handle most of the logic internally. The best example would be custom input that would handle passwords. It has 3 levels of required complexity, starting from the length of the password, to adding special characters as well as capital letters. As a part of my job as a system administrator, I set up VPS hosting using nginx as reverse proxy and Apache to serve files. I also deployed a mailing service as a replacement for Mailgun. Every project had automated build and deployment with Github Actions.
