React/Next.js Consultant (Short-Term Engagement)
We’re looking for a senior React/Next.js consultant with deep experience building high-performance web applications using TailwindUI. This is a short-term engagement focused on advising a small but ambitious engineering team with limited experience in these technologies. You’ll help us level up fast—through hands-on guidance, best practice recommendations, and strategic architectural input.

The ideal candidate is someone who has a track record of delivering performant, scalable, and maintainable frontends, and knows how to use TailwindUI efficiently to build elegant interfaces. You’ll be working directly with the Head of Engineering to review our existing web app, identify technical gaps or anti-patterns, and offer actionable recommendations. If necessary, you’ll also advise on a potential restructuring of the frontend architecture to better align with modern standards and long-term scalability.

We’re looking for someone who can clearly outline how they would structure this engagement—from discovery and audit through to recommendations and optional follow-on work. As part of your proposal, please include a rough breakdown of the steps you’d take, estimated time required, and the range of services you could offer beyond the initial review.

This is a remote, short-term consulting role and you need to be available for the synchronous tasks or meetings during India standard time 10am-10pm. Ideal for someone who enjoys high-leverage advisory work and helping teams grow into excellence or just an excellent engineer who has seen it all before.

Minor tweaks after it is built.The blog and clients page would be taken out. a new cover image would be used that is a video and a few image updates. Do you use Elementor? I would want it housed on another site till it is ready so the current link doesn't look broken.

Let me know what the fastest turnaround would be on this, the cost and when can get started.
