Frontend Development: with over 2 years of experience, I craft dynamic, responsive interfaces using React, TypeScript, and Next.js, enhanced by Redux and Zustand for state management. I ensure stunning designs with SCSS, Tailwind CSS, and Material UI, meeting the highest UX/UI standards.

Backend Development: i excel in building scalable server-side solutions with Node.js, NestJS, and Express, leveraging PostgreSQL, MongoDB, and GraphQL for efficient data management. My expertise in AWS (S3, Lambda) ensures robust and high-performing APIs for seamless client-server interaction.

Build & Configuration Management: i streamline development workflows with Webpack, Vite, and Rollup, optimizing build processes for peak efficiency. Using Git/GitHub and CI/CD pipelines via GitHub Actions, I automate testing and deployment, while configuring Nginx for reliable production hosting.

Testing & Reliability: I prioritize quality by implementing thorough testing with Jest, Cypress, and Playwright, covering integration and end-to-end scenarios. Tools like Storybook and React Testing Library help me ensure stability and performance across applications.

Library Integration & State Management: I specialize in integrating libraries like React Router and Zustand, alongside Redux Toolkit, to streamline workflows. My focus on Microservices and Event-Driven Architecture enables me to manage state effectively in complex, scalable applications.
