Hi - was in same rut few years back where I had taken up a non-dev role and suffered for a while to land the right dev role. To get back on track for interview and eventual hire as a dev I did a) Develop good skills in static typed programming lang (scala) b) Latest dev test deploy tool chain e.g mvn, sbt, intellij, ci/cd , and Docker c) The what part of data structures in standard libs d) developer level best practices in security , auth and authz method e.g oauth c) AWS d) improve interview programming skills i.e demonstrate interactively to solve small problems in scala or whatever e) learn the vocab used today .. not 4 years ago. Note - All of above is what applied to my situtation. And I apologize for not posting links for references. Thought I must share my experience.
