Portrait of the author against a blue background

I’m Ikhsan Sugiarto, a frontend engineer based in Jakarta, Indonesia. I build web and mobile products with JavaScript, React, Next.js, and React Native.

Most recently, I was a founding engineer at StroomChat, where I built the web and mobile experiences for a B2B SaaS chatbot platform. My work included a conversation inbox, chatbot builder, analytics dashboards, integration settings for Meta channels, and billing and credit-usage interfaces.

I also enjoy the product details behind reliable interfaces: application state with Zustand, schema validation with Zod, and thoughtful purchase flows. Earlier, I maintained and developed Next.js applications at Kasisolusi and built a React Native e-commerce app as an independent contractor.

This blog is where I share notes on building useful, fast software. Everything is available as plain text for humans and machines alike, and you can follow along via RSS.
