Hello, My name is Charles Bran. I have reviewed your job description and noted a few points to discuss with you. We have already developed similar platforms for cryptocurrency exchanges. There are several APIs for the currencies that we can use. 1. Yes we have similar experience in creating cryptocurrency websites. 2. We can only provide links on the chat discussion due to NDA purpose. 3. We'll create from scratch to keep the modules smooth and easy to update later. 4. Roadmap: Planning, Design, Development, Testing, quality assurance, Deployment,, Launch. 5. It will take 50 days minimum to create such websites. We'll discuss the final budget later. Charles.

Hello again, I have already bid at one of your reposts so repeating here. Answering your questions: - I did implement trade engine before in two variants - 1) Java/JSP and 2) PHP+Node.js Neither went online despite they had EUR 10K budget because they were never able to negotiate with banks and their imperative was to use fiat accounts. (the link https://www.freelancer.com/projects/php-graphic-design/complete-websystem-programming-design/) - Keep me as a backup option if you absolutely need links. But the project is pretty generic and not a problem at all for an experienced developer who is algorithm-aware and not just a coder. I have implemented much more complex things before (MMORPG engine, spatial warehousing algorithms, formulae interpreters, 3D visualization etc). - It is better to implement from scratch because out of box solutions often have undocumented issues that take a lot of time to deal with. You also lack control when using a 3rd party solution and it's bad to lack control over the most critical feature. Trading is not rocket science so I estimate manual programming effort as affordable within your budget. - The plan is - trade engine prototype first, then wrap it into the rest UX/UI features. I would like to use Node.js. - I work alone, 30 to 45 days. Your lower budget bound is fine. Message size doesn't let me write a lot, please respond to continue. You can repost this forever or just do it. Many Thanks, Sergei
