You may have an important Ruby or Python application that has served you well but is starting to fall over due to growth. Maybe it runs really slowly, crashes often or has tasks that never complete and keeping it up gets harder and harder. You’ve already upgraded your servers and it helped for a little while but its not going to get you where you want to be.
You may not be sure if its the database that needs the most attention or the service workers on the job queue that would give you the most ROI. And of course you can’t stand the idea of rewriting the app and anyway your engineers are busy with other work.
Most of it is probably working perfectly fine and its just a small part that needs attention. I can analyze your app and architecture, make concrete recommendations and together we can figure out what makes sense for you.
