Typescript/React Developer for LLM-Based Chat Application
We hired Anthony to help build our (React / Typescript / NodeJS) website, including an interface for a LLM based chat application. Over the 18 months that we worked together, he has never failed to deliver outstanding work. Not only was he able to complete every task asked of him quickly and well, but he volunteered recommendations and improvements to our development and deployment infrastructure that really benefitted us in the long run.
We were very particular about the outcomes that we wanted to achieve. Thankfully, Anthony was very responsive to feedback and was willing to work with us - sometimes through multiple iterations - until we got something that we were happy with.
Partway through his contract, we found ourselves needing additional help launching our mobile app, after the mobile contractors we hired proved not quite equal to the task. Fortunately, Anthony was willing to jump to lend a hand, even though the work was slightly beyond the scope of his original contract. What he didn’t know about mobile development he was quite willing to research and learn. With his assistance, we were able to successfully launch our app on both the Apple App Store and Google Play Store. We might not have been able to do so without his help, and certainly not as swiftly.
Overall, we have been incredibly pleased with Anthony’s work and can’t recommend him more highly.

Full Stack Typescript (React & Node.JS) Developer Needed
I found Anthony to be highly skilled and competent throughout our time together. He served as an active contributor to the team and the project, able to intelligently participate in design discussions and to help improve the final product from pre-production on through to final polishing, launch and subsequent live operations, in the ongoing development and deployment of post-launch feature sets. He was also able to pivot rapidly and help with related tasks, even if they lay outside of the scope of the original project. I would strongly recommend him for hire.
