I have a knowledge management system (Help Juice is the SaaS vendor). Information is organized in categories (folders) and articles nested in one or more categories. The system uses a standard taxonomy for all of the categories. Basically, I tried to create a "Dewey decimal system" for the information organized in the knowledge management system. The challenge is that users rarely need one article; they're reviewing information across multiple articles, or reviewing all articles across a certain category, or multiple categories at once, in order to compare information and conduct research. Instead of having hundreds of browser tabs open, I want to develop a program that will allow users to create custom "collections," which are essentially reports that assemble information on the knowledge management system however the users define it when creating a collection. In the attached PDF, I've illustrated how it would work. There would be a main page that would display any collections created by a user, and give the user the ability to edit a collection, delete a collection, or create a new collection. If a new collection is created, they could select the articles that they want to retrieve from the knowledge management system, and then they could view all of the information in one browser window. Eventually (though not important right now), I'd like for users to be able to receive notifications when articles in their collections have been updated. We're using Help Juice as our knowledge management system, but we don't have the ability to modify their databases. So, we're planning on using AWS as a database to store user's collections, and then using the user's help juice login id (email) as a key to store and retrieve collections stored on AWS. However, I'm open to other database providers. If you have any questions, please feel free to reach out. We're wanting to get at least a "rough and ready" version of this system operational before the end of the year, and will work to refine the UI and add additional features (like notifications) in Q1 2022.

SURFERforecast Refresh V2.0 – Stabilize and Upgrade backend of forecast.surfer.com and maps.surfer.com backend (Dot Net + Native ios + native android platform).  I am constantly needing to reboot the EC2 instances. Resolution: -Stabilize the .net backend and create new user management portal • Create new backend CMS to manage users • Move to a less expensive tier of AWS RDS or another database that is less expensive monthly • Export all login users and passwords to the new backend CMS (TBD) • Stabilize all • The AWS instance keeps timing out, please take a look at the backend and help fix the reason why it keeps timing out. *Considerations: • Will need to update Stripe, Google Analytics, Mailchimp, Revenuecat, etc • Will the ios/android apps - need to stabilize V3.0 Map Upgrades 3.1) We need to update the images on the (Southern California) react + leaflet maps so that the maps will have higher resolution images. There will be new images (tiles) from AWS s3 to be shown when a user zooms all the way into the screen in these geolocations. See screenshot 3.2) ​Add Maps for other regions: *best source for each new region is tbd Options: https://ift.tt/3drD9K1 https://ift.tt/31JoC9C https://stormglass.io Additional Maps (Add to the maps.surfer.com website) - Mexico (Will have S3 tiles for this region) - East Coast - Caribbean - South American - Europe - Pacific Ocean - Indonesia Considerations for other new region maps: * We need to restrict users to see 3 days of free forecasts, beyond that they will need to login and subscribe to access the forecasts via stripe * Need to make sure these maps have SEO and receive search traffic V4.0 – design / new re-imagined a version of the Forecast.Surfer.com Graphs, Favorites and Alerts, Social Feeds This could be ios/android only (depending on cost)? 4.1) – Graphs iOS/android and forecast.surfer.com **Need to be simple and engaging. Example: meetcarrot.com/weather/ Update the graph view of the forecast a. The “Day” view needs to be more simple and clean.   b. The layout should be “simple “, ie a user can quickly view simple forecast, referencing average data for 1am-6am, 7am-12pm, 1pm-6pm, 7pm-12am c. Simple chart and numerical values. User can then swipe to future/past days d.

This should be a small change in the code to fix. Alerts work already, they should just stay active until a user modifies or turns them off. *Add alert icon to maps.surfer * Show alerts % relative to forecast icon on the maps timeline Examples of current view on the live app  to follow) They will need to be updated or recreated 4.4 Social feeds (The “social feeds” should be almost ready to go live in the bitbucket code.  There will be Instagram galleries for each surf spot from the flockler API.   **We will need to talk through this if there are any issues with Flockler. *The social posts from that spot will reference the “timestamp” of that images post date. When a user looks at that image, they will see the surf, wind, etc conditions from that date/time.  (From Stormglass api) *A user will be prompted to set an alert to listen to when these conditions may happen in the future.  *A user can modify the alert settings, since the social post may not have the exact parameters for an alert.

We are a creative immersive tech startup going to market with an NFT frame to display NFT image and video assets. We began development on the web app and API to manage the NFT assets and serve the assets to the frame. The web app allows the user to connect their Ethereum wallet and add their NFT's to playlists, along with their NBA Top Shot moments and local image and video files. They can manage frame settings and which playlists are currently playing on their frames. They also have the ability to search for images on Giphy and add Giphy images to their playlists. They can do the same with OpenSea. The platform also supports lazy NFT minting, where we can bundle exclusive NFT's with the purchase of the frame and these NFT's will be stored locally until the user wants to transfer them to their ETH wallet, at which time they will be minted. The web app is roughly 75% complete but we have decided to part ways with the original developers. We are seeking a new developer to take over the project. The Android app that will consume an endpoint from this project and display these assets on our digital Frames using also needs a developer and it would be ideal if the same team worked on both: https://ift.tt/31vSO8g If you think you are a good fit for this project we would like to discuss the requirements with you.
