Hi! I'm Trevor

I create products that user's love, with a key focus on innovation, business goals, and technology.

With over 11 years of experience creating delightful user experiences, I love designing products that users enjoy while also aligning with business goals and the latest in technology. Currently, I'm at John Deere, where I'm dedicated to improving our core customer-facing experience. Before this, I gained valuable expertise at Tata Consultancy Services, where I contributed to a range of B2B and B2C projects across diverse industries. My journey has been all about innovation and shaping how we interact with technology.


Below are some key projects I've worked on in my career. If you are a recruiter or hiring manager, the password should be in my resume. You can also request a password by contacting me.

Bringing E-Commerce to Deere.com

Designed the configure and buy experience so that customers can effortlessly purchase small consumer equipment like lawn mowers from Deere.com. Empowered by multiple rounds of user testing, I simplified the configuration process so customers can confidently make purchases online.


  • Leveraged Figma variables to create a "functional" prototype for user testing
  • Conducted "holistic validation" by testing with all stakeholders in the E-Commerce ecosystem e.g. dealers

System and method for measuring user experience of information visualizations

The experience of information visualisations depend on multiple qualitative, quantitative, and contextual parameters which are often unmeasurable and incomparable. This patent relates to a system and method that collects, processes, and analyzes multiple parameters to profile the visualization. This is done by considering context by computing the chart complexity, benchmarking, summarizing parameters as hedonic and pragmatic scores, plotting on a scatter chart, and labeling based on scatter chart position.

Display screen with transitional graphical user interface for a gantt chart

This is a design patent that encompasses a variation of the gantt chart that enables comparing planned vs actual data. It also ensures insights are accessible on various devices include mobiles. This design visualises planned start and end dates, actual start and end dates, delays and leads, as well as current position as compared to the larger timeline. Furthermore, it enables user to drill deeper from tasks to subtasks to better understand project progress.
