About me

I’m Visy Lockhart, with 7+ years of .NET backend and full-stack experience (ASP.NET Core, Entity Framework, Angular), having built payment, shareholder-services, hospital information and airline CMS systems. I am also an FFXIV player and built Eranaut for the player community: a PWA I did end to end, from screens and API to screenshot OCR and Docker deployment, with a companion Discord bot, Eranarch. It was my first project built in collaboration with AI. I have a strong interest in game development and 3D. I have no professional experience yet, but Angular, Vue, OIDC and Docker were all self-taught and then shipped, and Eranaut went from zero to deployment the same way. I am confident I can reach my learning goals the same way.
