I have a sketch design for a new version of my personal blog site crunchingpixels.com. The current version of the site is built on WordPress and this version will be JAMstack. As seen in the attached recording of the preview you can get a feel of how it should look and work. Preview Prototype Desktop: https://ift.tt/31CDs2m Mobile: https://ift.tt/31CDtDs Source file is in Sketch is provided but here’s a quick look: https://ift.tt/3lNwApq I have a private github repo for which I have begun migrating existing content to sanity.io.  Access will be provided to winning bid. Technical expectations: - I’ve migrated most content to Sanity.io in which you will need to connect this app to and possibly adjust settings in Sanity.io accordingly. - I’d like this site to be developed in the latest versions of React & TypeScript.

I need someone to build an API key management app. The app will have a React-based Front End (I have Metronic theme, wireframes and mocked up pages). The back-end will be Spring Boot REST microservice/ Gradle / PostgreSQL. The app is called Console and it allows users to login and manage (create, revoke, etc.) their API keys. The app also lets the superadmin (me) go in and manage everyone's keys (i.e. view, revoke) The key generation process will need to follow an approach used by Coinbase like here: (link removed) So here is the process: 1. A brand new user comes to a static landing page and requests an account by submitting their email address in a form (The form will have 4-5 other fields like name, company name etc.) This request is stored by Console. In config file, if "autoApprove" is false then the user is told they will hear back from me shortly. 2. If autoApprove is false - A superadmin (me) goes into Console app and approves or denies that request. if autoApprove is true, then the request is automatically approved and we move to next step 3. Once approved, the user is notified via a SendGrid email containing a unique URL. The URL is valid only for 24 hours. If the user clicks URL within 24 hours it will take them to a registration page specific to them and marks in the db that their email address has been confirmed. If it is after 24 hours, a new link is emailed to the email address. 4. On the registration page they enter account password (with confirm password) and  submit. The password is stored in DB. The password is stored as + 2 salts is hashed. They are then redirected to the login page, where they login. 5. If successful they are taken to Console's Dashboard page where they can generate an API key. This is done by accepting from the user a passphrase (also stored w/ 2 salts / pepper hash) and giving them an API key and secret in a dialog box reminding them to store it safely and that it cannot be provided again. The API key is stored on backend but the secret is not. 6. When an API is called, it will have 4 headers. The backend code to check and test these headers must work for 2-3 dummy API endpoints you create. The 4 headers are: instamint_access_key, which is the api key instamint_access_sign - base64-encoded signature (See Coinbase link above) instamint_access_timestamp - a timestamp the client is making the request in Unix Epoch in UTC instamint_access_passphrase - the passphrase the user selected The API call will execute only if the timestamp is 15 seconds before or 15 seconds after the current time 7. If an API key is shown anywhere on screen it, a reference portion is shown with the rest masked with asterisks with an eye icon to enable its visibility / reveal it if clicked 8. If a user revokes an API key, that API, passphrase, secret is no longer valid 9. A user can have more than one API key. 10. Every time a user creates a new API key, a new passphrase is requested, and a new key and secret are provided 11. A superadmin can see, search for all users and keys and revoke a key or the entire user. Revoking a user revokes all keys. Once keys are revoked, they cannot be used again (it is final) 12. For the login into Console I would like to integrate 2FA, by use Google Authenticator( See here: (link removed)) 13. Superadmin credential are loaded from environment variables on Boot startup (i.e. bootRun) The secret should be large and complex. For example, here's a secret: lmfsOr4S/UeIi55ihcktOQ2Wzh5WIFFj7S1/aqkGa/eiqt18wl3Sm2h/ehsILU03K5YDgNwMF2uaBumrcCbKqQ== Budget: $425 Posted On: December 09, 2021 15:24 UTC Category: Full Stack Development Skills:React, Java Country: United States click to apply via All jobs | upwork.com

I have an application that includes quiz questions. There is a progress bar showing how far through the quiz a user has reached. When a user answers a question correctly, I want to trigger an animation located on the question's box in the progress bar (see file for a visual and the component hierarchy). This should involve two main tasks: 1. Create a functional animation component that can be used with a useEffect hook by the course component on the event of a successful submission. This animation can be converted from the normal JS one here for use in React: https://ift.tt/3oFXKke 2. Create a callback function from the question component to the course component that will let the course component know the location of the question component in order to render the animation correctly I am open to other implementations if you know a better way of doing it, and I have a lot more React work like this if I like the results. Required Skills: Must be fluent in written English Tasks will include: Create functional React animation hook IMPORTANT: To prove you’ve read this assignment, please write I READ YOUR REQUIREMENTS in the first line of your bid.  I will eliminate all bids that do not start with this phrase since many people do not read requirements.

I have a large prototype for a real estate application that has some complex interactions. The project is 90% complete but there are some performance issues and some clean-up that needs to be done before this can be presented. I'm looking for someone who is an expert in Figma to help assess the best way to get the prototype to feel natural. This could be a combination of addressing performance issues, adjusting animation timings, or interaction types (hover vs mouse enter etc).  Some of the issues that need to be addressed: *generally slow, this is a large file. Is there a way to break this up? *hover effects are delayed, especially in the floor plan view edit mode *images are blurred when loading, this is distracting for hover effects *menu navbar interactive component dropdowns not consistently interactive across prototype pages (reset overrides? another issue?) *hover effects sometimes seem to get triggered in a delayed way and then stack up, ie a bunch of hover effects will happen all at once after a delay where nothing happened *GIF animations not playing consistently in the interior walkthrough (too large, an issue with the GIF file?)
