Hi, I will finish your Manifest V3 extension and get it production-ready without rebuilding what already works. I'll audit the existing code, fix the broken flows, tighten the service worker and Chrome Storage logic, and add a secure license-key check. You will receive: Fixed dashboard and profile flows Working license-key authentication Stable MV3 build ready to publish I understand you want the current foundation preserved, so I'll patch carefully and test each module. Ready in about 5-6 days after code access. 1) Which features are currently broken or incomplete? 2) Where should license keys be validated? Best regards, Shayan

I understand you already have a substantial Manifest V3 Chrome extension and need an experienced developer to audit, repair, and productionize the existing codebase—not unnecessarily rebuild it. • Review the supplied source code/documentation and map the current architecture before making changes • Diagnose incomplete features, runtime errors, messaging issues, and broken data flows • Work confidently with Manifest V3, JavaScript, Service Workers, Chrome APIs, and Chrome Storage • Stabilize communication between dashboard/content scripts/background service worker • Review and fix REST API integrations, import/export, profile/account, saved-form, status, and printing workflows • Implement secure license-key authentication with proper server-side validation rather than relying on client-side checks • Improve UI/UX while preserving the existing architecture and functionality • Debug service-worker lifecycle, permissions, async operations, storage, and extension-state issues • Test critical workflows and edge cases for production readiness • Provide clean, maintainable changes with clear communication and revisions as needed • I can start immediately after reviewing the codebase and documentation Approx. timeline: 5–10 days for audit, fixes, license integration, testing, and stabilization; exact timing depends on the current code condition. Please message me with the source/documentation overview, and I can start with a structured code audit immediately.

Hi Azamgarh, You need the existing Manifest V3 extension reviewed, broken parts fixed, UI refined, and a secure license‑key system added without rebuilding from scratch. I see you require: reviewing the dashboard and profile management code, repairing incomplete functionality, improving data flow and UI, integrating a license authentication, and ensuring stability for production. I will audit the current codebase, patch the service worker and messaging logic, refactor the UI with vanilla JavaScript, add license‑key verification using Chrome Storage encryption, run end‑to‑end tests, and deliver clean documentation. I recently delivered a Chrome extension that incorporated secure licensing and passed Google’s verification in record time. I provide an upfront estimate, send proactive updates, test thoroughly, and hand over full source with docs. Will the extension need to support multiple Chrome profiles, and is there a preferred method for license key generation? Looking forward to your reply.

You already have an MV3 foundation. The job is not a rewrite: review the architecture, fix broken flows, tighten UI and data paths, and add a secure license-key auth path so the extension is production-stable. The flow: read your codebase and docs, map dashboard, storage, service worker, messaging, and API edges, fix incomplete modules, implement license-key validation without blocking legitimate users, harden Chrome Storage and runtime messaging where it is fragile, then ship a first production cut you can load and test. I work TypeScript/JavaScript daily on production systems (Cloudflare Workers, REST, client-facing apps). Chrome MV3 and service workers are in that same toolkit. I will not rebuild from scratch unless something is technically unsafe. Phase 1 in about three days after I have the repo: auth path + highest-impact broken flows, with a short list of what remains if anything is out of scope. Share the private repo (or zip) and any license-server notes you already have and I will return a written review plus first patch plan the same day. Can you send access?

✔Hey! Client! I am really confident in your project building. Plz review my proposal carefully and reach out to me directly.✔ I have rich similar experience with this kind of Chrome Extension development, Manifest V3, JavaScript, Service Workers, Chrome APIs, REST integrations, licensing, and debugging existing codebases. ✔ First review your current extension architecture, dashboard, storage model, messaging flow, APIs, background worker, import/export, payment UI, printing, and incomplete modules without rebuilding working functionality. ✔ Fix broken features, improve UI/data flow, resolve Manifest V3 service-worker lifecycle issues, strengthen error handling, and make Chrome Storage/runtime messaging reliable. ✔ Implement a secure license-key authentication flow using server-side validation, expiration/device or account rules as required, with no secrets embedded in extension code. I’ll also test installation, updates, API failures, storage persistence, permissions, and production packaging before handover. Timeline: 5–8 days Fixed price: ₹12,500 for the agreed priority scope. Two questions: Is there already a backend/API for license validation, or should I build that too? Which features are currently broken or incomplete and should be prioritized first? Best regards, Dipak

@priyanshuk879

Hi, I can review and improve your existing Manifest V3 Chrome extension without rebuilding it from scratch. I’ll first understand the current architecture, service worker, Chrome Storage, messaging, and API flow. I can fix incomplete features, improve the UI, and clean up data flow where needed. I’ll also implement a secure license-key authentication system and handle the related API integration. I’ll test Chrome APIs, REST calls, import/export, and existing modules for stability. My focus will be on fixing the current code properly while keeping the existing foundation intact. I’ll debug issues across the extension and prepare it for a reliable production release. I can review the source code and documentation first and then share a clear plan and timeline. Ready to start Immediately.

@prachia77

Hii, Your extension already has a solid Manifest V3 foundation, so rebuilding it from scratch would be unnecessary. We can work directly with the existing codebase, understand the current architecture, and focus on completing the missing functionality and making it production-ready. We can review and debug the dashboard, profile management, Chrome Storage, service worker, runtime messaging, API integrations, import/export, status and printing modules. We’ll also improve the UI/data flow and implement a secure license-key authentication system with proper validation and API communication. Recommended stack: JavaScript, Manifest V3, Chrome APIs, Service Workers, Chrome Storage, REST APIs, and jQuery where already used in the existing codebase. Our approach will be codebase audit → identify incomplete/broken flows → fix and test core functionality → improve UI and data handling → implement license authentication → validate API/service-worker communication → cross-scenario testing and production preparation. We’ll keep the existing architecture wherever practical. I’d be happy to discuss your vision and suggest ideas to make Fabulous Garments stand out online. Looking forward to working with you! Best Regards, Prachi Webix Infotech

@abdurr531

Hello, I can take your existing Manifest V3 extension, understand its current architecture, and turn the incomplete/broken parts into a stable production-ready build without unnecessarily rebuilding what already works. Your existing setup—Chrome Storage, service worker, runtime messaging, REST APIs, import/export and dashboard modules—makes an architecture-first debugging approach important. I would first trace the current data flow and identify the actual blockers before making changes. I can help with: • Manifest V3 and Chrome API debugging • Background service worker and runtime messaging • Chrome Storage and data-flow issues • REST API integration and error handling • Existing functionality and UI improvements • Import/export and status/printing modules • Secure license-key authentication flow • Payment-related UI and account functionality • Production stability and regression testing I have strong JavaScript, API integration and existing-codebase debugging experience, and I prefer improving a working architecture rather than replacing it unnecessarily. I’ll work from your source code and documentation, test each affected workflow, and provide a clean final build with the important changes clearly documented. Bid: ₹10,000 Estimated completion: 5–7 days If you share the source code and the current list of incomplete/broken features, I can start by identifying the highest-priority issues and give you a clear implementation plan. Thank you.
