JavaScript/TypeScript Engineering Support

I’m developing a product whose codebase is written entirely in JavaScript and TypeScript, and I need an experienced engineer to keep momentum moving forward. The upcoming work ranges from implementing new features to tightening performance and eliminating bugs, so fluency across the full development cycle—coding, reviewing, and testing—is essential. You’ll be working in a Git-based workflow and collaborating with me asynchronously; clean, well-documented pull requests that compile without errors and include relevant tests will count as completed deliverables. If you’ve previously built or improved modern JS/TS applications and can jump comfortably between frontend components, backend logic, and test suites, I’d like to hear about it. When you reply, please share a concise example of a recent JavaScript or TypeScript project you led or contributed to significantly, along with the specific challenges you solved. I’m ready to start as soon as I find the right fit, and I value clear communication and quick iteration.
