Industry Experience

Software & Internet, Professional Services, Computers & Electronics
    paper Personal Website

    This is a personal website built with React and Next.js, designed as a digital portfolio and creative space for myself. The site features a modern, minimal aesthetic with smooth transitions and a focus on user experience. The layout is responsive, ensuring accessibility across devices.

    Design and Structure

    Landing Experience:
    First-time visitors are greeted with a dynamic title card introducing Lucian as a developer, artist, and plumber. Returning users are taken directly to the main content, with navigation handled by a fixed, stylish navbar.
    Navigation:
    The site uses a tabbed navigation bar for seamless switching between the Home, About Me, and Viața la Țară sections.
    Profile Card:
    The home page features a profile card with a photo, a brief description, and quick links to contact via email, GitHub, and LinkedIn.
    About Card:
    The About section details Lucian’s background, education, and technical skills (React, Next.js, TypeScript, Node.js, Angular, MySQL, PostgreSQL, Azure). It also links to a downloadable CV and highlights interests in photography and digital art.
    Viața la Țară Section

    “Viața la Țară” (Life in the Countryside) is an interactive gallery and search experience for my personal photography and digital sketches. Users can:

    Search Images:
    Enter keywords (in English or other languages) to search through a curated collection of images, with intelligent translation and filtering for relevant results.
    Drag & Interact:
    Displayed images can be freely dragged around the screen, resized to fullscreen, or removed, creating a playful, tactile experience.
    Modern UI:
    The gallery uses animated placeholders, smooth fade-ins, and a visually appealing, glassmorphic design for search and image controls.
    Technical Highlights

    Built with Next.js and React for fast, client-side navigation.
    Uses TypeScript for type safety and maintainability.
    Responsive, mobile-friendly CSS with custom modules for each component.
    Integrates third-party libraries like Headless UI and Lucide React for icons and UI elements.
    Dynamic image search with translation support and interactive drag-and-drop.
