What I'm looking for

I seek roles owning end-to-end platform work, emphasizing reliability, testing, measurable product impact, cloud-native infrastructure, and practical AI features.

I am a Senior Software Engineer who builds and ships customer-facing and internal platforms across education benefits, healthcare, and commerce, with a strong bias toward reliability, testing, and smooth releases.

I own work end-to-end from designing workflows to implementation, enterprise integrations, and production support, turning messy requirements into simple, maintainable solutions teams can extend.

I bring practical AI/ML experience focused on smarter matching, search, and automation, and I’ve delivered across full stacks—React/TypeScript, Go, Java, Python, Ruby on Rails—and cloud platforms such as AWS, GCP, and Azure.

My track record includes reducing operational handoffs, improving reliability and observability, migrating platforms (Heroku→AWS), and shipping measurable product improvements through testing, CI/CD, and disciplined rollout practices.
