Full-Stack Developer Needed to Build Adaptive Restaurant Booking Dashboard (API + Manual Flows)
Brian helped pick up a part started and scoped project with extremely complex requirements. We were extremely impressed by how he was able to hit the ground running in spite of a lot of ambiguity and add value right from the start.
He is able to communicate extremely well as part of a cross-functional and remote team working environment, as well as working independently to problem solve in his areas of competence. Excellent level of both spoken and written English.
We highly recommend Brian for full-stack development, user testing, front end UI & Azure deployments in large or small projects.

Experienced Full Stack Developer Needed for Exciting Project
Working with Brian is always a great experience. He’s professional, easy to communicate with, and consistently writes clean, well-structured code. He’s hired as a full-stack engineer working with Next.js, TypeScript, Prisma, and Node.js in business intelligence and cloud integration, and he's got strong technical skills and a clear understanding of project goals to everything he works on. Recommended.

Brian went above and beyond on this project, taking a true vested interest in making sure it was done right. He didn’t just complete tasks—he fully embraced the project, treating it as his own and proactively solving challenges along the way. His willingness to jump in, take ownership, and ensure things were handled with care made a huge difference. His dedication and engagement were truly appreciated. Also appreciate him introducing some much needed typescript standardization to the project.

The types of project I usually work on are business management tools.
Think Stripe, Trello, tools. Platforms where users can visualize, manage, and update their data. The application allows them to process their data: automating repetitive tasks, connecting services, they can have multi-user workflows et-cetera.
These applications have complex databases to describe different business objects that the application needs to be able to create, read, update, and delete information. They often deal with a lot of dynamic data that changes over time. Creating this complex business logic is a core part of the work that I do.
I excel best if you need one person who can work and take responsibility for the entire life cycle of your application(s).
The core technologies I work with are Next.js, Nest.js, TypeScript, and SQL. Around that stack, I work with a wide range of different cloud services, libraries, ORM, and third-party API's and tools
