About

I’m a C# developer working full-time in a corporate environment and an indie maker building products outside my day job. Daily Streak was my first project beyond .NET. I learned React, Vite, Supabase, Vercel, and Stripe while building it over nearly two years, with AI as a development tool and feedback from friends and family. I’m now building Subscription Tool, which helps people keep track of recurring costs and renewal dates. I enjoy learning new technologies, shipping useful software, and improving it through real feedback.
