You will get a Chrome extension or automation dashboard in React or Next.js
Project details
I build Chrome extensions and automation dashboards that turn repetitive browser or data work into a usable tool. This can include a Manifest V3 extension, React/Next.js dashboard, content scripts, data capture, API integration, CSV/Excel export, reporting, and a clean workflow your team can use after delivery. Best fit for founders and teams that need a working automation tool, not a vague prototype.

About John
React / Next.js Developer for Chrome Extensions and AI Web Apps
Ibadan, Nigeria - 11:34 pm local time
Recent proof includes:
- JsonExport, a privacy-first browser tool that converts large nested JSON files to Excel, CSV, and HTML client-side without uploading user data
- Dainty Proofreader, an AI-assisted proofreading product built around precise, controlled editing workflows
- 49Blox, product work for a digital music collectibles platform
- Universal Undo, a shipped Android utility app with a live public presence on the Play Store
My strongest fit is work like:
- Chrome extensions and browser workflow tools
- React / Next.js dashboards, SaaS features, and internal tools
- Python automation for scraping, APIs, CSV, Excel, and reporting
- AI-powered product features with practical UX
- API-heavy products that need frontend, backend, and automation logic working together
Clients usually hire me when they need more than page-building. I am strongest when the work needs product thinking, clean implementation, hard integrations, and a UI that feels intentional instead of patched together.
I can help with:
- building a Chrome extension MVP, side panel, content script, or Manifest V3 workflow
- turning a rough idea into a usable React / Next.js MVP or dashboard
- cleaning up or extending an existing frontend codebase
- connecting APIs, automation, scraping, and AI behavior into one coherent product
- shipping browser-side tools where privacy, speed, or workflow quality matter
- solving messy implementation problems that stall less experienced developers
I also bring deep Android and system-level experience, which makes me especially effective at debugging edge cases and handling technically awkward projects.
If you need someone who can own product logic, frontend quality, browser automation, and integration-heavy delivery with maintainable code, send a message with the problem you are trying to solve.

Confirm workflow and technical scope
