CV

I am a full-stack developer with experience in creating high-quality web applications. I have a deep understanding of both frontend and backend technologies, which allows me to effectively work across all stages of project development. My experience includes:

  • Codebase Migration and Optimization: I have implemented migrations of outdated codebases to modern frameworks, such as Next.js, updating routes and introducing new development approaches.

  • Interface Development: I have created adaptive and cross-browser websites, including landing pages, educational platforms, and CRM systems, using React.js, CSS/SASS for styling, and ensuring responsiveness.

  • Code Typing and Stability: I utilized TypeScript to improve code typing, which helps reduce errors and increases code stability.

  • Performance Optimization: I have conducted optimizations of website load times, which positively impacted the overall user experience.

  • Technical Collaboration: I worked closely with designers and backend developers to integrate APIs and create functional applications.

I specialize in web application development based on a modern technology stack: Next.js (frontend), NestJS (backend), Drizzle and Prisma (ORM), PostgreSQL (database), TanStack Query (data management), and React API. My focus is on performance, optimization, and usability.

    Website

    HTML & CSS
    In this project, I implemented responsive web design with modern web standards in mind. The main objective was to create a website that renders correctly across different devices, from mobile phones to desktops. This involved creating responsive components, utilizing media queries to ensure proper content display on various screen sizes, and optimizing the site for fast performance.

    Technologies Used:

    Next.js: The main framework used for the website, providing server-side rendering (SSR) and static site generation (SSG) capabilities.

    React.js: Used to create interactive components that manage dynamic content on the pages.

    TailwindCSS: Employed for efficient and flexible styling, enabling the creation of responsive interfaces without writing extensive custom CSS.

    TypeScript: Used to enhance code safety and ensure proper type-checking throughout the project.

    Lucide icons: Integrated for visually appealing icons that enhance the user interface.
