What I'm looking for

I'm looking to build scalable, high-availability products where I can own complex integrations, automate workflows, and contribute to reliable delivery through strong engineering practices.

At Coreplan, I build mission-critical systems for State Attorney General Offices, including a DJE integration that automated judicial communications across four-plus offices and improved legal communication delivery speed by about 40%.

I've delivered Ruby on Rails features, third-party API integrations, background processing, and production hotfixes for thousands of public-sector users. I also build responsive applications with React.js and Next.js, contribute to AI-powered workflow automation, and help teams ship reliable, testable software through code reviews and CI/CD-driven deployments.
