Full Stack Developer
It's been a true pleasure working with Steven and I am grateful for all of the incredible contributions he has made and continues to make with our startup. He is an excellent communicator, providing detailed updates and breakdowns to keep me in the loop of his progress. I appreciate how he really took the time to understand the product before diving in. Along the way, Steven's eliminated tech debt, and got us back on track as we head into the summer.
This contract was marked as complete purely for administrative bookkeeping purposes. Steven and I continue to work together on a separate Upwork contract. Thanks Steven!

Frontend Dev for B2B platform/mktplace (React, Typescript, CSS, GraphQL, Vite)
Steven was a great communicator and very professional when he delivered for our project, starting early in 2025. Steven just 'got it', and was direct and open which makes working with remote team members so much easier. He helpfully provided occasional video updates and explainers, and was able to work async as agreed. I'd recommend his skills & services.

Front-End Developer
Steven was the lead frontend developer on our project, and we couldn't be more happy with his work. Steven is incredibly professional and knowledgeable, not only performing well above and beyond our expectations, but he was also very intuitive with regards to the overall structure of the development work across the team and contributed deeply towards the overall betterment of the companies direction and architecture. Needless to say, it was an absolute pleasure working with Steven, and we cant wait to work with him again in the near future!
