What I'm looking for

I seek roles where I can build and ship user-focused web applications, lead technical decisions, and continue rapid prototyping across full-stack technologies.

I’m a full-stack engineer with 3+ years of experience building and shipping production web applications, with a strong eye for user interfaces and rapid prototyping.

I've rebuilt production sites, led technical decisions for new features, and maintained a 100% job success score across 40+ freelance projects, delivering solutions for US and international clients.

My projects include real-time collaborative platforms, AI-powered search for consumer health products, and multiple client production sites; I specialize in TypeScript/JavaScript stacks, modern frontend frameworks, backend services, and cloud infrastructure.
