Hi, I’m Kon,
I help companies reach their product vision with Advanced Prototyping techniques. MSc Digital Design and Design Engineer, with 7 years of experience working across Europe and US.
From early wireframes to detailed UI flows, I focus on creating interfaces that solve real problems, take advantage of the client techstack to bring intuitive and efficient solutions to customers.
I work extremely confidently with engineers and product managers, ensuring that deliverables balances user, business and technical needs and are implementable in short time. With a track record in Smart Home, Energy, E-commerce, Healthtech and cross-platform design, I bring a systems-thinking mindset to every challenge.
Most importantly, I build highly interactive prototypes with ProtoPie that help teams align early, test faster, and uncover critical issues before it gets expensive. They’re perfect for usability testing, stakeholder buy-in, and cross-team understanding.
Research is baked into my design process, not an afterthought. I can provide integrated prototype user testing via Useberry and Prolific, with auto-recruitment of participants based on client’s segmentation needs.
Dive deeper at partheniadis.com and I can offer 8 hours free prototyping to see if it works for your organisation. Available, today!
Best,
Konstantinos Partheniadis.
