Hi!
I've read your requirements regarding to your project - Softphone connecting to SIP/PBX, ReactJS & Django
From 8 years ago, I started working with Javascript.
Deep knowledge of Javascript (ES5, ES6) / Typescript will be assurance of great project.
I always stick to a result-driven working manner with great attention to detail, periodic thorough code review, and critical thinking.
The best quality, accurate timeline, free and polite after-service are what I guarantee to my clients.
Please send me a message to discuss the project.
Thanks.
