I'm Alex, and I love building delightful web apps.

I specialize in modern UI architecture, real-time interfaces, and developer-friendly systems—mostly with Svelte / SvelteKit, TypeScript, and Node.js.

I've worked on production systems ranging from consumer-facing applications to developer tools and blockchain-enabled platforms. My experience includes owning complex frontends, designing APIs, integrating real-time data flows, and shipping features used by thousands of users in high-stakes environments, most recently at Radix DLT.

I care deeply about how software feels to use. Performance, clarity, and trust matter more to me than shipping features for their own sake. I enjoy working close to product thinking, questioning requirements, and finding the smallest solution that actually solves the problem.

Recently, I've been building and shipping my own products, contributing to open-source, and exploring how to design systems that scale—technically and cognitively. I'm especially interested in teams that value craft, ownership, and long-term thinking over buzzwords.
