Project details

I build modern SaaS websites and applications using Next.js, with scalable architecture, clean UI, and production-ready features like authentication, payments, and CMS integration. This project is designed for startups who want to launch fast and grow with a solid technical foundation.

For design, you can either provide your own UI/figma files, or I can build using modern UI systems like shadcn for a clean and fast result.

If you need fully custom UI/UX design, it can be provided as an additional service.

Chrome Extension Development Jianchao helped us a lot, one of the best people I've worked with out of the 50+ people I have worked with on this platform. Super experienced and very detail oriented in getting to know your problem and what needs to be built (hint: most engineers will jump into coding asap and deliver bad architechture that will ruin your product). Really wonderful to work with Jianchao and shipping our product out.
