I’ve been writing software for about 20+ years, mostly full stack. I’ve worked on everything from internal tools to customer-facing platforms. These days I enjoy building smaller projects and experimenting with ideas on my own.

EmailCheck.dev

EmailCheck.dev is a fast, developer-focused API for validating email addresses in real time.

It helps prevent fake or low-quality signups by checking syntax, domain validity, MX records, and disposable email providers.

Built for simplicity and speed, it’s designed to fit seamlessly into modern signup flows without slowing down the user experience.
