What I'm looking for

I seek a role where I can own full‑stack delivery, improve system design and performance, work with strong engineering practices, and grow into technical leadership; open to relocation.

I am a senior full‑stack software engineer with extensive experience delivering production systems across Next.js and .NET ecosystems, emphasizing system design, performance, and developer experience. I have a track record of stabilizing behind‑schedule projects and driving high‑impact deliveries.

I have owned end‑to‑end full‑stack development, refactored critical backend and frontend components, optimized database queries and application data flows, and implemented centralized logging and monitoring that reduced debugging time. My work has directly improved product stability and user impact for platforms with thousands of active users.

I contribute to open source and have built complete products from concept to deployment, including medical and eCommerce applications; I am judged by peers for reliability and effectiveness and am open to relocation for the right opportunity.
