Iโ€™m a hobbyist fullstack developer with about 8-ish years of experience building software, with a strong focus on backend systems and web applications. On the backend side, I work with a variety of stacks depending on the projectโ€™s needs, including TypeScript (Express, NestJS), Python (FastAPI, Flask), Java (Spring Boot), C# (ASP.NET), and Golang (Gin). Iโ€™m comfortable designing APIs, handling authentication, working with databases, and building scalable services. For frontend and fullstack work, I build web apps using React, Next.js, Solid (or SolidStart), Angular, Svelte (or SvelteKit), and .NET Blazor. I also do mobile app development using React Native, Flutter, and Kotlin Multiplatform, but my main strength lies in backend architecture and fullstack systems. If you need something done, hit me up and we can work something out!
