A multi-tenant sales platform that unifies how DSS and master-dealers sell cameras online, replacing spreadsheets and manual order workflows with a single, trackable system.

I joined as a freelance front-end engineer to design and implement the web across three applications, collaborating with the back-end team and integrating into their .NET + SQL stack.

I also owned deployment end to end, setting up GitHub Actions pipelines that build and ship the applications to Portainer so changes move from commit to production with minimal manual work.
