Hey, I'm Jin Lei

I'm a Lead Web & Application Engineer based in Singapore, with over 14 years of experience designing and developing large-scale web and mobile applications.

I focus on building solutions that are scalable, maintainable, and crafted with the user in mind.

JavaScript Is the Core

JavaScript and React are my core tools of choice — used daily to build business features and enhance internal automation for the team.

From complex UI components to backend scripts, if JavaScript runs there, I can build for it.

Tiny Learning, TinyFrontend

To make frontend learning more fun and approachable, I launched TinyFrontend in 2023 — a platform sharing bite-sized, practical knowledge every day.

Since then, it’s grown to over 14,000 followers — and the journey has only just begun.

Some Apps

I’m not exactly a coffee lover — but a bit of caffeine helps keep the gears turning.

Over the years, I’ve also built a few productivity tools and personal enhancement apps to stay on track.

Feel free to check them out!
