PyDen welcomes seven new members to the Denver development community! These students recently graduated from Devetry's nine-month Code Forward program. The students began with no prior knowledge and are now deploying full-stack applications in Flask, Vue, and Postgres, using AWS-RDS and Heroku. Coming from a diverse set of personal and professional experiences, the students are thrilled to show off some of their most recent applications to the PyDen community.
