Security Header
Hi *****NOTE THIS IS DONE IN THE HOSTING NOT THE WEBITE. THE PLATFORM AUTO ADDS TOO THE WEBITE**** I need someone who is an expert in adding security headers. If you have not done it before & only think you can do it, please do not apply. Below is what I need done: (These are within our hosting platform & will be used as a standard profile for our clients). X-DNS-Prefetch-Control This header controls DNS prefetching, a feature by which browsers proactively perform domain name resolution on both links that the user may choose to follow as well as URLs for items referenced by the document, including images, CSS, JavaScript, and so forth. X-Frame-Options Used to indicate whether or not a browser should be allowed to render a page in a , , or . X-Content-Type-Options Is used by the server to indicate that the MIME types advertised in the Content-Type headers should not be changed and be followed. Referrer-Policy This controls how much referrer information (sent via the Referer header) should be included with requests. Cross-Origin-Resource-Policy This response header conveys a desire that the browser blocks no-cors cross-origin/cross-site requests to the given resource. Cross-Origin-Opener-Policy This response header allows you to ensure a top-level document does not share a browsing context group with cross-origin documents. Cross-Origin-Embedder-Policy This response header prevents a document from loading any cross-origin resources that don't explicitly grant the document permission (using CORP or CORS). Strict-Transport-Security This response header lets a web site tell browsers that it should only be accessed using HTTPS, instead of using HTTP. e.g max-age= X-XSS-Protection This response header is a feature of Internet Explorer, Chrome and Safari that stops pages from loading when they detect reflected cross-site scripting (XSS) attacks. e.g 1; mode=block Content-Security-Policy This response header allows web site administrators to control resources the user agent is allowed to load for a given page. e.g default-src https:; Content-Security-Policy-Report-Only This response header allows web developers to experiment with policies by monitoring (but not enforcing) their effects. These violation reports consist of JSON documents sent via an HTTP POST request to the specified URI. e.g default-src https:; Expect-CT This header lets sites opt in to reporting and/or enforcement of Certificate Transparency requirements, to prevent the use of misissued certificates for that site from going unnoticed. e.g max-age=86400, enforce, report-uri="https://foo.example/report" Permissions-Policy This header provides a mechanism to allow and deny the use of browser features in its own frame, and in content within any elements in the document. e.g I need this done ASAP ****************PLEASE STATE HOW MANY HOURS WORK THIS IS FOR YOU.***************** ****************MAKE SURE YOU ANSWER THE QUESTIONS****************** David A.i.H.

I have QR codes on various electronic devices and I am hoping to 'check in' these items. Such as like a checklist to make sure i have them. The current functionality is that I scan a QR code using the mobiles rear camera. The application decodes the QR code and checks if the prefix of the QR code matches a certain requirement based on conditions stored in a JSON file stored on my server, if it matches then a jQuery popup is shown with the decoded data. This system is currently working but I cannot make the 'check in' functionality work.

I can provide all code and files and the QR code format if needed.

Google Tag Manager (GTM) & Cloud Platform (GCP) Python & JS Code
I manage tracking, tagging, and scripts on Google Tag Manager (GTM) and Google Cloud Platform (GCP) for a number of websites, and need someone to help me with this. Experts with JavaScript AND Python development experience and expert-level familiarity with Google Cloud Platform and Google Tag Manager required. You must be very conversant with GCP, have used the systems extensively, and ideally know how to manage and code on GCP's app engine + VMs. On GTM, if you have experience creating your own templates, scripts, and even work with server-side GTM setup, that would be ideal. IMPORTANT: Work will be done side-by-side. YOU WILL NOT HAVE DIRECT ACCESS. Code can be developed separately on GitHub, but to make it live it will have to be done in a call where I have access and you guide me on the steps. Similarly, for GTM, I will export containers in JSON and you will need to work on that offline. At times you may be asked to assist me with writing code in short sprints (1-2 hours per day) and testing GCP / GTM on live site previews. You will not be given direct access to the GTM containers at any point, but will be sent container export files, will then work on the updates in a sandbox environment and send back an export, which I will review and implement on the live sites. This will be an on-going programme over a number of months, with the right person. The average expected project time requirement will average 20 hours per month.
Javascript code to be re-written optimised to be more efficient
We have a script (javascript) that has been written for a test application we have in our telematics platform that generates a JSON payload and forwards it to an end point which works ok. What we are finding however is that the timestamp of the data collected versus the time stamp on the execution is between 3-5 seconds behind and we'd like to find away of optimising the code to reduce the latency as much as possible.
