It may handle millions of requests, provides a thunder-fast response to your client's browser without delays. The transparency indicates the API health. Every experienced developer should remember one, but the simple rule - before start solving the problem, you have to understand it. As a team lead, I can code, grind, prioritize and spread tasks to developers, consult developers on best practices, review the quality of the final product. I have rich background sorting bespoke and non-standard solutions: * e-commerce and merchants with further ePOS integrations; * contributing platforms; * bare metal configuration; * building a blockchain exploration infrastructure. Existing apps optimisation When everything getting global, a gigabyte of technical articles, lessons, modules and ready to use solutions, appears to available on the internet every hour, free or paid - don't care, moreover - don't care the way they were written. Seriously, I started meeting the IT-guys and developers more often than other professionals. And this is a good thing, I believe that a wide variety of competitors will make the whole direction of programming and software development stronger. Or not? Well, the answer to this question could be a little tricky. In one hand, here is an entire development industry available for everyone, in another - your app may not be ready for the real world: * Real loads - peaks, DoS and DDoS. * Availability - downtime, page speed time and page load. * Marketing - SEO and social media. Sometimes your app can and should be optimized, sometime - not, it should be re-engineered for your fixes or new needs.
