Project - Bionorica DE Key technologies: Vue3, Nuxt, Vuex, TypeScript, Tailwind CSS, GraphQL, Contentful, Stackbit, Nestjs, Vite. • Significantly improved efficiency by optimizing components and configuring the Vite bundler. • Successfully improved the delivery processes and was the initiative of making retrospective meetings within the team. • We used Contentful headless CMS, where I created numerous complex UI components with a wide range of variations and settings. These components enabled flexible integration into any application, significantly enhancing our ability to adapt and scale quickly. • Actively promoted improved communication within the team, and as advocated the use of new approaches and technologies. • From scratch developed Slack app with its own personal admin panel (Front-end and Back-end). • Had key involvement in estimating timelines for implementing new applications ----------------------- Project - Global PT Security Key technologies: React, Next, Zustand, MobX, TypeScript, Tailwind CSS, Strapi, TanStackQuery. • Had key involvement in estimating timelines for sprints and new features. • Improved communication with the DevOps team on the customer side to speed up task completion and requirements elucidation. • Significantly improved efficiency through query optimization. • We used Strapi, where I implemented many complex UI components with complex relationships and a wide range of variations and customizations. ----------------------- Project - ALL GOAL Key technologies: React, Next, Redux Toolkit, TypeScript, Tailwind CSS, PWA, AI, ThirdWeb. • Worked as a lead front-end developer at a startup, where we developed the application using Progressive Web App (PWA) technology. • Key contribution to the project was the introduction of new ideas to the startup, constantly striving to make the application as user-friendly as possible.

• I taught beginners javascript, typecript, react and redux from scratch to full-fledged trainees. • Developed thesis projects together, helped students to understand the inner workings of IT and helped each of them personally by pointing out their mistakes and what could be improved during development.

Project - Trinity BNB faircrypto game • Worked on a crypto game project, where our team developed the application from scratch to release, achieving a reach of 3000 new users. We used Progressive Web App (PWA) technology to create the application. • Primary responsibility was implementing key UI components and the logic for user interaction with the game through the MetaMask and TrustWallet crypto wallet. • One of the main challenges I addressed was tracking a large number of states and synchronizing user data to ensure accurate payouts to users. This involved developing robust and reliable mechanisms for state management and data synchronization.

Project - CIP • Served as the key back-end developer for a corporate application designed to assist employees with client interviews and internal interviews with managers. My primary responsibilities included developing services to create sequential stages for various interviews and saving these in the user’s personal archive. • In addition to my development work, I also participated in mentoring other developers, providing guidance and support to help them improve their skills and knowledge. My contributions ensured that the application was robust, reliable, and user-friendly, ultimately helping employees navigate the interview process more effectively. • Worked as the front-end developer on a project to develop a corporate social network from scratch, aimed at enhancing communication between teams. I played a key role in optimizing the application and implementing a live chat feature using web sockets. • My responsibilities included designing and developing the front-end architecture, ensuring high performance and responsiveness, and integrating real-time communication features. This project allowed me to leverage my expertise in front-end development to create a seamless and interactive platform that facilitated better team collaboration and communication

Worked on various projects, which helped me quickly master new technologies and improve my understanding of JavaScript. During this time, I delved deeper into React and began learning Node.js, which later enabled me to participate as a full-stack developer in other projects. In this role, I held a junior developer position, focusing primarily on enhancing and fixing bugs in existing functionalities. I was always proactive and engaged in discussions with senior developers, which accelerated my growth as a developer. My initiative and willingness to learn allowed me to rapidly develop my skills and contribute more effectively to the team’s success
