Welcome

With almost a decade of experience in the industry, I’ve had the pleasure of working with a global tech giant and a startup, covering end-to-end product design for all devices, accessible user experiences, design systems, brand definition, and visual design.

Experience

During my career, I’ve had opportunities to experience it all: working solo, in small and large teams, collaborating with multiple teams, stakeholders and designers to reach alignment on design decisions. I’ve worked from home, in both busy and quiet offices, travelled for work a lot too. I bring “can do” attitude, plenty ideas, and positive vibes to a workplace.

Secret projects

Most of my work is confidential. If you wish to have a deeper dive, drop me a quick message and I'll send over the secret case studies.

Other projects

Creative endeavours have occupied most of my free time for as long as I can remember. I enjoy exploring my abilities in all possible areas of the design realm. Creating is what fuels my existence and solving usability problems in everything that surrounds us gives me sense of purpose. If you’re curious of what I do for fun, I’ve got you covered, have a snoop!

Kudos

“Aga is a force of nature when it comes to UX design. She is inquisitive and curious, with strong energy and fun personality. It was a pleasure working alongside her!”

“Aga is a UX force of nature. She doesn’t solve problems; she attacks them. She has a truly infectious energy that makes even the toughest challenges achievable. Working with Aga I marvelled at her technical expertise and was often shocked at just how much deep thinking had taken place from session to session. It’s genuinely exciting to work alongside her.”

“I worked with Aga for over three years, where she led our design team and built the foundation of our design system. She’s super quick with prototyping, has great design instincts, and excellent communication skills. Her design skills are outstanding both in web and mobile, and she has leadership skills to manage cross-team projects and conflicting requirements. Aga is a passionate teammate who cares deeply about her work, and is extremely fun to work with!”
