Clients Love Our Work

We brought Tania in to do some early design work for Quesbook, and it was a wonderful experience from start to finish. She took the initial design direction and built it out into a thoughtful design that fit in beautifully with our brand. Not only was she great at communicating and meeting deadlines, but the collaboration process was made the relationship so easy. Will definite hire again!

Silvia Tueros-Cossioย โ€” Design Director

Tania created a beautiful, clean, on-point mobile app prototype for Android in inVision. I'm very happy with it! She possesses both technical and design skills, with a eye for aesthetics. This combination was my primary concern from the inception of the project, so finding Tania was a relief. From the first contact, I was impressed with Tania's quick grasp of what I was attempting to accomplish and with the clarity and crispness of her responses and queries. She delivered as she promised and at no time was I in doubt. I look forward to working with her again should the occasion present itself.

Steven Riley

Tania was exceptionally responsive to our needs and intuitive with the creative work. She stayed with us through the entire process and made sure we were successful technically and creatively.
