I am looking for someone with a lot of flask/sqlalchemy/javascript experience who will take a very basic annotation tool we developed, add features such as user management, project management, templates, improve the codebase etc. For example: The admin would be able to create a "face annotation" project, and decide that in each image the users need to use a polygon tool to mark the entire face, place points on eyes and mouth, and select from a dropdown menu if this is male or female. The code needs to be flexible so that such schemes can be easily defined by the admin in a web-interface or using simple xml (or similar). The admin can also define how many times each image should be annotated. Annotation templates should allow some sort of logic, for example if selecting "male", the admin can decide that the user have to answer another question (e.g. has beard? yes/no) or perform another annotation task (e.g. tag beard with polygon) Once the project is created and the annotation scheme defined, the admin can upload images and associate users with the project. When a user logs in, they are served with one of the images which was not yet annotated, and they can click "face" to annotate the face with a polygon, click "left eye" to annotate the left eye with a point, answer questions etc. viewing/grabbing the results should be easy. I will add you to our git repo and start the contract with a phone call explaining the scope of the project and the features required in more detail. Hopefully this short project can evolve into a longer gig - there's way more stuff we need to implement!

I've been developing a Rails app that is 95% complete. All intended functionality has been implemented in a development environment, however some work is required to rectify bugs in production and complete the RSpec testing suite. My Rails app is deployed on Heroku. I require assistance with the following three outstanding areas of my app: 1) I use ActiveAdmin to manage projects/courses. I'm able to add projects using ActiveAdmin in development, however Heroku returns an error when I try to add or view projects in production. 2) I use Stripe as a payment processor, which allows customers to purchase projects/courses. Stripe's test functionality works as expected in development, however I'm getting strange errors when I run integration tests for the Stripe iframe. I need assistance updating my tests so the Stripe integration/feature tests pass. 3) Where possible, update unfinished tests so that test coverage is increased. I will give the successful freelancer collaboration rights to my Git repository and Heroku production repository.

Resource: We are looking for MAC IT support for application setup, security, communications, logging, and other initial system configuration tasks. This is a hands-on role with a small initial scope focusing on basic, up-and-running conditions for our local network. Environment: We have a small, heterogeneous network with Local, Remote, and Cloud Systems that need to be integrated for PG Admin and pgsql management tools and operations. Currently we have Windows Server, a server-sized MAC, and a Dell server running RHEL. However the primary target for the scope of this proposal is the MAC Security: The MAC needs firewalls and virus and intrusion security configuration. The router has a firewall and an OpenVPN access that works but needs hardening. Communications: The primary objective includes establishing connectivity among all systems for terminal communications by Putty and VNC PG Admin, pgsql, and GUI DB Tools. All systems should be enabled for communication and bi-directional remote Postgres interactions. Logging: Logs for Postgres and the primary security systems should be located logically and be exposed through well-known display features and roll-over procedures. We intend this work should be specified in advance, include a review of the systems and the specific technical operations to be performed, and should proceed quickly to the goals as specified. Specifications, schedule, and time and effort logging will be communicated exclusively using our Jira instance and configurations and other assets will be managed on our Bitbucket instance. Please provide us with specific assurances that you feel capable of meeting the requirements and why you believe you have those capabilities. You may also refer us to descriptions of your previous jobs, but we will pay more attention to those who respond with specifics about our requirements.
