The perfect mix

creativity + logic + passion

Let's achieve great things together.

I am an independent designer living in San Diego, CA, but I can help you wherever you are.

Why should you work with me?
  • I am small and mighty: I will offer you the same quality of the big guys but also personal attention and care.

  • I am passionate about design, whether online, on paper or in the classroom.

  • I can help you reach your goals on time and on budget, and you will enjoy the whole process.

About me


Let me introduce myself: I am Tiziana (Tee-ts-eeh-ah-nah), and while I am originally from Milano, Italy, I have lived in California for more than half my life. I created Tdag Design in 2002.

I am an UI/UX designer, front-end developer and graphic designer. I have a strong web knowledge and a passion for it, but my first love is Graphic Design, and I am very well versed and experienced in both. I have been teaching classes on both media for more than 15 years.

I specialize in helping small business and non-profits, but I can help you no matter what business you are in. I believe in giving it all and building lasting relationships.

How can I help YOU?

I listen to you, the client, to your needs and desires, and I find the perfect solution to your design problems. I pride myself on always being on time and on budget, and I am fun to work with, to boot.

I can help you


I pride myself on excellent customer service and attention to details.

I believe that the best kind of design achieves the client's goals more than simply satisfying the designer's ego.

User Experience
& User Interface

User Experience (UX) is the process of creating a more engaging design, by creating a delightful experience. I will help you push your site to new heights by providing a better flow and design, one that is a better match for what your users are looking for.

Front-end Web

I design responsive websites that work well on any device, and any situation. Performance is always one of my top priorities, so your site can work well even with a slow bandwidth. The mobile version will always work just as fast as the desktop one, if not faster. While I am aware of, and familiar with the latest trends & technologies, I will choose the perfect tools for your project, whether it is a small static site, a dynamic and animated one or a complex, customized Wordpress theme.

Print &
Graphic Design

You never forget your first love: while I spend much of my time online, for work and fun, I still have a soft spot in my heart for traditional graphic design, print and paper. Print can drive scores of new customers to your business, both online and off line.I will help you from concept to final product, including print supervision, paper selection and specialty techniques.
