What I'm looking for

I am seeking a senior engineering role to build scalable, secure AI-enabled SaaS in healthcare or fintech, with ownership of architecture, cross-functional collaboration, and opportunities to mentor and grow engineering teams.

I am a Staff Software Engineer with 11 years of experience delivering scalable, high-performance SaaS solutions across healthcare and fintech. I focus on reliability, security, and user experience while integrating AI to solve real-world problems.

I have driven production AI-powered clinical documentation, virtual assistant chatbots, and secure payment systems, reducing provider documentation time by 35%, improving staffing forecast accuracy by 22%, and supporting millions of active users with 99.9% uptime. I built low-latency payment and monitoring systems that processed hundreds of thousands of transactions daily while reducing chargebacks and improving approval rates.

I thrive designing full-stack, HIPAA- and PCI-compliant architectures, mentoring engineers, and collaborating with clinical, product, and data science teams. I seek opportunities where I can own architecture, scale AI integrations, and lead cross-functional delivery to maximize user impact.
