ABOUT SIDI

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, combining presales engineering, full-stack development, and FDE delivery: from customer requirements and solution design to Python/Django platforms, agents and workflows, Daytona sandboxes, web and Flutter implementation, and enterprise and communications integrations. I also build and ship independent apps.

Based in Shenzhen, China
