What I'm looking for

I’m looking to build and ship high-quality, user-focused web products where I can combine strong frontend/backend engineering with devops and performance optimization. I value deep customer trust and long-term partnerships, and I enjoy translating ideas into polished, usable experiences.

I am a Full-Stack Developer passionate about creating web applications end-to-end, with deep experience across frontend, backend development, devops, and performance optimization. I translate concepts into engaging designs, applications, and websites that improve usability and user satisfaction, while prioritizing deep customer trust and high product quality.

In recent work, I built interactive 3D experiences (including seamless 3D rendering), documentation platforms using Next.js with Mermaid and OpenAPI via ReDoc, and sports analytics features spanning live video streaming and editing. I also own reliable delivery practices—implementing blue-green releases on AWS with CloudFront caching, S3/Glacier configuration, and custom security policies—alongside building collaborative WebRTC tooling and TypeScript scaling workflows from Contentful GraphQL.
