I BUILD THE PART BETWEEN "GOOD IDEA" AND "IT'S LIVE."
I'm Sidi, a senior software engineer across Apple platforms, React Native, web, backend, AI, and automation. At EPAM, I delivered enterprise mobile products and led a native-to-React Native upgrade for an app with 4M+ DAU, raising crash-free rate from approximately 90% to 99%. I began contributing to Typework in November 2025 and worked directly with 4-5 enterprise customers, coordinating requirements, partnering with sales on technical proposals, and driving full-stack implementation, UAT, and delivery. These presales, full-stack, and FDE responsibilities span Python/Django platforms, agents and workflows, Daytona sandboxes, web and Flutter, and enterprise and communications integrations. I also build and ship independent apps.
Based in Shenzhen, China

Away from code, I'm usually watching anime, playing games, experimenting with hardware, or building something that began as "this should be easy."
