PTC Velocity is a Sales Enablement Platform, powered by SAVO Group. The goal of this project was to revamp the web UI and navigation that result in better user experience.
User Research • Prototyping • UI Design • UI Development


Though its purpose is to enable better sales process, PTC Velocity’s bad UI and poor content organization were not tailored to fit the needs of our daily users, the sales reps and partners reps.
We knew the website refresh needed to start from home. The old homepage did not serve much of its purpose. Randomly placed announcement banners and unclear buttons on top made the homepage to look confusing.
With the this project, we wanted to accomplish following goals:


To learn more about our users’ experience with the current site, we conducted user interviews and usability testing. Based on the feedbacks we collected, we were able to identify 3 major user behavior using this platform.
“When I go into Velocity, I care more about information design than pretty looking UI. As long as I can find contents as quickly as possible, the better.”
Many users struggled navigating through pages to find the right content. We needed to find the best way to make their discovery experience easy and seamless.

The design process consisted of card sorting, information architecture, task flows, and creating low-fi/high-fi wireframes.



If you are a power user looking for obscure IPA files, cracked paid games from years ago, or specific developer tools, Senumy might feel limited. It focuses on popular, high-demand apps rather than a massive backlog of software. Competitors like AppDB or Signulous (paid) offer vastly larger libraries.

While no free signing service is perfect, Senumy generally maintains decent certificate stability. Free certificates often get revoked by Apple, causing apps to crash, but Senumy is usually quick to update or provide fixes, minimizing downtime compared to some smaller services. senumy ipa library best

This is the holy grail. The version on Senumy includes a joystick for GPS spoofing, auto-walk routes, and a "quick catch" feature. Because Senumy uses anti-ban certificates, it has a lower ban rate than other libraries. If you are a power user looking for
Unlike massive repositories that host broken or outdated files, Senumy focuses on high-demand, verified IPAs.

Standard applications modified to unlock premium features.
(general) — if you're looking for a safe, reliable source for IPAs for sideloading (with a developer account or tools like AltStore, SideStore, or TrollStore), popular ones include:
There is never a perfect design! We had a lot of positive feedbacks from our users with the redesign. Users were satisfied with cleaner UI and improved navigational experience.
However, even the new design could not satisfy our users 100%. As they continued using the tool, they faced with new sets of problems. I learned how important it is to never get fully satisfied with the design decisions and the continue the effort of iteration, which should not be an option but a habitual routine.
