I have a degree in Communication & Multimedia, where i gained competences in the fields of design, illustration, programming and audiovisual. I'm responsible and i'm always willing to learn more.

Since 2003, I've been designing and building websites that help businesses sell, convert, and grow — combining UX, visual communication, and front-end implementation in one workflow. I've worked with startups and e-commerce brands, improving conversion, customer experience, retention, and overall product quality. I focus on what actually impacts business performance: clarity, trust, usability, speed, and scalable design systems. I’m not a template installer or a designer creating trendy concepts for Behance that never go live. I work on real products with real customers, real constraints, and real business goals. What I help businesses with: • Increasing conversion rates through better UX, clearer structure, and stronger product presentation. • Creating premium-looking e-commerce experiences that feel trustworthy and easy to buy from. • Improving retention through cohesive customer journeys — from landing pages to email flows. • Reducing friction in shopping experience and making stores easier to navigate and scale. • Building websites that are fast, maintainable, and designed for long-term business growth. • Turning outdated or inconsistent stores into polished, conversion-oriented products. What I can handle end-to-end: • UX/UI audits with actionable business-focused improvements. • Full website redesigns and development. • Shopify and WordPress websites from scratch. • Custom landing pages and product pages focused on sales performance. • Email templates and retention-oriented customer experience systems. • Design systems and scalable UI architecture for growing brands. • Front-end implementation with clean, lightweight code instead of bloated builders. I combine strategy, design, and development to create fast, scalable websites that look premium and perform in the real world.
