John Stuppan

Back to freelancing after a year at Lübbering GmbH. I build full-stack applications with React, TypeScript, C# / .NET, Python and Node.js, work with PostgreSQL and MongoDB on the database side, and deploy on AWS and Azure.

I also take on projects outside the standard web dev scope. I am proficient in automation, computer vision and Unity game development..

Spent a year building internal software for complex engineering workflows at a mechanical engineering company, covering everything from requirements to deployment using .NET and React. Migrated critical Visual Basic scripts to C#, which significantly improved stability and cut down maintenance overhead. Also designed and built a component-based configuration engine for complex drilling systems that lets sales staff put together full system setups without needing an engineer in the loop.

100+ completed projects for IT service providers and SMEs across web development, automation and scripting, with a 97% positive rating on Fiverr. Core stack is React, TypeScript, C#, Python, Node.js, PostgreSQL and AWS. Clients ranged from simple websites all the way to complex B2B integrations and enterprise PowerShell automation rolled out across 2,000+ workstations at 11 company sites.
