Senior software developer for ongoing work on patented nutritional app

I am seeking a senior developer for ongoing work on a patented nutrition app (see [login to view URL]). The work will exceed 3 months but will be less than 30 hours per week (as needed work to fix bugs and add new functionality).


Ruby on Rails (Ruby 2.6 / Rails 6)

Vue.js / Webpacker


Stripe API





Active Admin



Minimum 5 years direct experience building and maintaining a Heroku-based app

A positive, can-do attitude -- this app and its potential for helping millions of people regain their health is exciting to you, and you are thrilled to be a part of its expansion! You offer ideas for functionality and visual improvements.

Bonus -- you have an intrinsic passion for health and wellness!

Excellent communicator -- you provide same-day response to work requests, keep me informed of your progress regularly during a project, and ask questions promptly when you need clarification.

Dependability -- you meet your promised deliverables in terms of quality and deadlines.

Good eye and fastidious attention to detail -- I won't find function errors or poor graphic formatting in your completed work.

You provide accurate estimates of what is involved in and the time it will take to complete a given project.

Minimum 95% positive feedback from Upwork clients.
