About me
I’m a software engineer who enjoys solving difficult problems and building things that actually work.
I work mostly with Node.js, TypeScript, React, Next.js, Java, PostgreSQL, and AWS. I’ve worked on fintech platforms, business applications, APIs, and AI-powered products.
I care about understanding the problem before writing code. If you have an idea, an existing project, a bug that’s driving you crazy, or a backend that needs work, send it over. I’ll help you figure out the right solution and build it properly.
