Hello, my experience in web service development and admin parts is 17 years. I will gladly help you implement your service. The main thing I do is carefully ensure that you do not have to redo things when the load increases by laying down the correct architecture from the start. I am very well acquainted with Web3 and Telegram development.
Budget: 20000 UAH Deadline: 7 days
Hello,
I’m interested in working on the Loka project and helping strengthen the backend for your Web3 real estate rental application.
I have 9+ years of backend development experience and solid expertise in building and maintaining reliable APIs, integrating third-party services, and optimizing system performance. I’ve worked with secure signing flows, external verification APIs, and complex business logic where data integrity, speed, and reliability are critical.
For your project, I can help with:
QES integration: implementing and stabilizing the electronic signature flow via API, including validation, error handling, and secure contract confirmation.
API bug fixing and optimization: reviewing existing endpoints, improving performance, and ensuring predictable behavior under load.
Backend reliability improvements: logging, monitoring, and refactoring weak points to make the system faster and more stable.
Clean, maintainable code with clear documentation for future development.
I’m comfortable working with Web3-related products, Telegram-based applications, and systems that require a high level of security and compliance. I’m also open to long-term cooperation and transitioning to a permanent role after successful delivery.
I’d be happy to discuss your current architecture, timelines, and expectations in more detail.
