We built a new tool called re_dms in order to allow streaming replication of data from postgres to redshift. Here, we’ll outline why we needed this new tool, our technical considerations,and some challenges we overcame.

Last year, our Heroku Postgres database was fast approaching its 3TB storage limit, the maximum size that Heroku supports at time of writing. To make sure our community of 4 million people could continue to work on their financial health with Cleo, it was essential to migrate away from Heroku as quickly and smoothly as possible.

You didn’t hear it from me, but Cleo Engineers aren’t perfect. We have bugs. We have quite a few of them. Our relentless focus at Cleo is to make it as simple and joyful as possible for our users to level up their relationship with money.

The ineffable cool that is Cleo Designer, Corinne Hitching, needs no introduction. Designers, or anyone who’s reading, please enjoy this exploration with one of our original Cleo designers.

The benefits of Typescript in a team environment for building and maintaining production-worthy codebases are nothing new. At Cleo we committed early to developing our web and mobile apps with Typescript to give us the safety of static typing when developing our product.
