Senior Frontend Developer Needed for Next.js Project Hiring Mohammad Mesum was one of the best decisions we made for this project. He delivered a pixel-perfect, responsive frontend with Next.js and Tailwind that exceeded our expectations. His code is clean and well-documented, making handoff a breeze. A true senior developer and a great collaborator.

If you need a developer who thinks like a founder and ships like an engineer send me a message with your project details and let's build something great together.

Steps for completing your project

After purchasing the project, send requirements so Mohammad can start the project.

Delivery time starts when Mohammad receives requirements from you.

Mohammad works on your project following the steps below.

Revisions may occur after the delivery date.

Order & Submit Requirements

You purchase the catalog and provide bug details, project access, logs, screenshots, and expected outcome. Delivery time starts once I receive all required information.

Analysis & Root Cause Diagnosis

I carefully review your Lovable, Bolt, or Supabase project, reproduce the issue, identify the root cause, and create a clear fixing strategy.

Review the work, release payment, and leave feedback to Mohammad.
