What I'm looking for

I am seeking remote senior/staff engineering roles at US companies paying in USD, where I can lead teams, drive performance and cost optimizations, and deliver scalable web and mobile products.

I am a Staff Software Engineer with 10+ years building scalable fintech, media, and SaaS solutions, combining deep frontend and backend expertise with proven leadership from prior Navy service. I lead remote teams to deliver MVPs quickly and drive cost and performance optimizations across cloud platforms.

My technical strengths include React, Next.js, Astro, React Native, TypeScript, Node.js, NestJS, GraphQL, RESTful APIs, microservices, AWS, and Azure, and I have a track record of cutting AWS costs by 80% and improving performance by 50%. I have delivered production systems for high-profile clients including Nike and built real-time, high-throughput dashboards and streaming/mobile applications.

I am open to senior or staff remote roles with US companies paying in USD, and I bring a strong blend of engineering craftsmanship, DevOps discipline, and leadership to help teams ship reliable, performant products.
