Ensured that projects are built with best practices and optimized for performance.Developed and maintained the server-side layer using Node.js and Express, ensuring efficient communication between the web application and external APIs.Built robust, scalable RESTful APIs and microservices, focusing on performance and security.Integrated AWS services for cloud-based deployments, storage solutions, and scaling, ensuring high availability and fault tolerance.Designed and implemented real-time features using Socket.IO, enabling functionalities such as live notifications and real-time data updates.Worked extensively with Nest.js and TypeScript, writing clean, maintainable, and type-safe code that adhered to SOLID principles.Collaborated with the team to ensure seamless integration of Telegram Bot API, automating workflows and enhancing user interactions through bot systems.Ensured code quality and stability through rigorous testing using Jest and integration tests, maintaining high test coverage.Utilized version control systems (Git) and project management tools to ensure smooth collaboration and tracking of deliverables.

-Building a front-end admin part using ReactJS, Redux and MaterialUI.-Building a server-side layer(node.js) for proper communication between web-app and API.-I was responsible for building Frontend UI by using React and I made pixel-perfect and responsive websites with the given Figma/XD design and make them work on various kinds of browsers and mobile devices.-Used Redux(toolkit)/Context to manage state and props and I often use functional components with Hooks and HOC(Higher Ordering Component).-During the development, made reusable components and write SOLID, well-structured, well-commented, and clean code to make other team members read and understand my code for teamwork.-Responsible for testing by using Jest / Enzyme and version control and team/project management services and tools.

-Our super-fast E-commerce application was made to help anyone start their very own online shopping at ease.-Built with React, Next.js, TypeScript, Tailwind Css, our app promises to deliver an interface for the business that is quickand easy to use.-Used the latest Next.js features (e.g. middleware to high-order authorization), optimized SEO up to 70% with Google meta tags and search console.

-Improved code quality and stability by removing flaky tests and increased test coverage from 50% to 90% with Next.js,unit and integration tests.-Contributed to code consistency and fast ramp-up of new team members by reviewing 2-3 pull requests daily and by mentoring new team members with onboarding.-Improved team onboarding by introducing 3-4 documentation files on project architecture and local project setup.-Delivered features: online chat (uses websockets for real-time remote control), screen annotation and more.-Optimized the whole CRM system and decreased load times for heavy reports up to 2 times by caching old data.-Decreased latency for our read queries by 40% to increase availability by efficiently using redux-toolkit -Optimized sending huge amount of information by Formik to keep safety, and prevent from useless reloading
