Ad Libitum Voices Website
I designed and developed the official website for Ad Libitum Voices, one of the most recognized pop-opera vocal groups in Southeast Europe. The site showcases the band’s identity with an elegant, performance-driven layout that highlights their story, music, concert schedule, and media presence. Seamlessly integrating audio playback, a dynamic gallery, and a ticketing-ready structure, the site offers fans and organizers an immersive, informative experience. Fully responsive and optimized for speed, the platform reflects the sophistication and artistic spirit of the group.

AdVantage Media Agency Website
I crafted the AdVantage Media Agency demo site as a sleek, single-page experience that guides visitors from an attention-grabbing hero statement to clear calls-to-action. Crisp typography, generous white space, and subtle scroll-triggered animations keep the focus on the agency’s story, values, and team, while strategically placed “Get a free consultation” buttons drive conversions. The build is fully responsive, performance-optimised, and easy to scale, showcasing my ability to fuse brand narrative, visual design, and code into a high-impact digital presence.

SlipNFlip Website
I designed and developed the SlipNFlip online store, a modern e-commerce platform dedicated to stylish slippers and flip-flops. The site blends a clean, minimalist aesthetic with playful branding elements, creating a fresh and inviting shopping experience. Featuring dynamic product showcases, promotional highlights, and a seamless checkout flow, the store is optimized for both desktop and mobile users. Clear typography, bold calls-to-action, and engaging product imagery drive user engagement while ensuring easy navigation. Built on a flexible and scalable foundation, the site not only reflects the SlipNFlip identity but also supports future growth, seasonal promotions, and brand storytelling through its integrated blog and content sections.

Nexify Logo & Branding
I designed the Nexify logo and branding for a modern tech startup specializing in mobile and digital solutions. The concept focuses on minimalism and innovation, with a bold sans-serif font paired with a stylized gradient “X” to represent progress and digital transformation. The clean typography and striking color contrast convey professionalism, trust, and a forward-thinking identity.
The branding system was designed for versatility, ensuring seamless use across web interfaces, app icons, business stationery, and digital media. By keeping the design scalable and adaptable, Nexify’s identity communicates clarity and impact whether used in print or online environments.
