    paper Zyara Beauty Lounge & Spa Branding

    This project was created for Zyara Beauty Lounge, a beauty and wellness brand seeking a refined, luxurious identity to better reflect its services and attract a premium clientele. The client’s main goal was to establish a cohesive brand presence that communicated relaxation, trust, and modern elegance while standing out in a competitive spa market.

    One of the key challenges was balancing luxury with warmth. The brand needed to feel high-end without appearing cold or unapproachable. To address this, I developed a visual direction using soft, calming colors, clean typography, and minimal yet elegant design elements that reinforced a sense of comfort and professionalism.

    Another challenge was ensuring the brand identity would remain consistent and adaptable across multiple platforms, including digital media and physical applications. I solved this by creating a flexible branding system that maintains clarity and recognition while allowing for future growth.

    The final result is a polished, scalable brand identity that aligns with the client’s vision, supports their business goals, and positions Zyara Beauty Lounge as a trusted, premium beauty destination.

    paper PANGAIA Organic Cotton – AI SEO Audit & Optimize

    For this project, I completed a full SEO audit and optimization for the PANGAIA Organic Cotton Collection product pages. The main goal was to improve performance, boost search engine visibility, and create a smoother shopping experience for users.

    I began with a technical SEO audit, identifying and fixing issues such as SSL/mixed content warnings, broken internal links, outdated sitemap settings, and slow-loading images. These fixes improved site security, crawlability, and overall performance.

    Next, I optimized on-page SEO elements, including titles, meta descriptions, and headers, aligning them with target keywords while keeping them user-friendly. I also enhanced the internal linking structure, ensuring product pages were easier to navigate and better indexed by search engines.

    To further improve speed and usability, I compressed large media files and reviewed third-party integrations, removing outdated or unused elements. I also cleaned up custom scripts and code to maintain stability and functionality.

    The project concluded with a detailed SEO report outlining completed tasks and future recommendations. As a result, PANGAIA’s product pages became faster, more visible in search results, and more engaging for customers. This project highlights my ability to deliver practical SEO solutions for e-commerce and fashion brands, with clear, measurable results.
