Hello! I am ready to complete this project and have extensive experience developing various applications.
Budget: 12000 USD Deadline: 40 days
Hello.
I have experience in developing desktop and backend solutions, working with low-level integrations and interactions with devices. I understand the overall architecture of such tools (unlocking, firmware, working with authorization and the server side).
I am ready to understand the task, study the details, and propose an implementation option. We can discuss the requirements, development stages, and timelines.

Hello!
My name is Alexey, and I represent the NC-1 development group. For over five years, we have specialized in building high-performance software, including mobile applications, ERP/CRM systems, and complex e-commerce solutions.
I am pleased to propose our dedicated team for the development of your GSM Unlocking Tool MVP (similar to Chimera Tool):
Project Team:
Project Manager – Coordination, milestones, and reporting.
System Architect (Senior) – Secure server architecture and protocol design.
Backend Developer (Middle+) – Authorization server and license management.
Mobile/Desktop Developer (Flutter) – Cross-platform tool interface.
UI/UX Designer (Middle) – Intuitive dashboard for device management.
QA Engineer (Middle) – Rigorous testing with physical hardware.
Recommended Tech Stack:
We recommend using Flutter for a high-performance cross-platform desktop/mobile interface, paired with Node.js (NestJS) and PostgreSQL for a secure, scalable backend. This stack ensures fast authorization and efficient handling of device-server communication.
Preliminary Estimate:
Cost: $12,000
Timeline: 70 working days
I have several ideas on how we can optimize the MVP architecture to reduce both the budget and the development timeline without compromising the security of the unlocking protocols.
Our Portfolio & Case Studies: https://1drv.ms/b/c/b7a0d31a9dae1bc5/IQCpK38gmEvWT6F_Cso40Li-AXAKkSs-J67mCwll-C732pw?e=v4VVF5
I look forward to discussing the technical requirements and the roadmap for your tool.
Best regards,
Alexey M.

Hello!
I represent the Devoxen development team. We have experience building desktop applications and integrating with external services and APIs.
We can help with developing a GSM unlock tool, but it would be important to clarify: are you planning to build it from scratch, or use existing services/APIs?
We can deliver a stable application with a user-friendly interface, device interaction logic, and backend integration.
We work in stages with clear communication, and after launch we stay available for support and further improvements if needed.
Looking forward to discussing the details and proposing the best approach for your project.

Hello. I have extensive experience in developing complex software, including desktop and low-level solutions involving work with devices, protocols and server-side components.
The project concept is generally clear from the description, but the task is currently too vague; therefore, more detailed information regarding the functionality and scope of work is required for an accurate assessment.

Hello. I am ready to assist with the development of a GSM tool, including a desktop client and backend infrastructure (authentication server, licensing, user management), similar in concept to Chimera or Android Multi Tool.
I have experience in building desktop applications (C# / Electron), integrating ADB/Fastboot, and developing scalable backend systems with secure API and access control. I can design and implement the core architecture, device communication layer, and a reliable licensing system.
Given the complexity of such solutions, it is advisable to start with a defined MVP (limited set of devices and functions) and scale the system progressively.
