Consultant cloud infrastructure expert

PLEASE READ THE REQUIREMENT FULLY BEFORE APPLYING. THANK YOU. Our web application is delivered via a mobile app using WebViews. So while it is a mobile app (both iOS and Android), the actual content is a normal website, loading in the (shell) mobile app. And so the same content can be viewed on a web browser too, through a URL. Our app becomes slow regularly. We need a cloud infrastrurure expert to look into why our app slows down, and under what circumstances it slows down, and fix things. We are hosted on DigitalOcean currently, in a Bangalore data centre. Our stack: Angular, Laravel (PHP), MySQL, ElasticSearch, Redis, Linux, Memcached, Docker, Kubernetes We are looking for people who can debug our speed / performance issues (hands-on). Your fundamental role would be make our application fast at all times. This will most likely be a one-time assignment to fix all current issues, followed by a retainership arrangement. We would like a person who is available across the week - not just on weekends and not just after work hours. So if you are a dedicated freelancer (i. e. not someone who already works somewhere full-time and only has some spare time after work), it would be great. We are located in Hyderabad, India. We will pay well for the right person, and the pay is negotiable. When applying, we would appreciate and respect it if you were elaborate about what your skills are and why you would be a good fit for this. Thank you.
