Integrating Yaml into Meteor.js application (intricate)

Use following DBs: [login to view URL] in order to create autocomplete function for skills, certificates (bunch of skills), and items (that require skills). Code needs to be able to calculate for time needed to achieve a skill from a certain starting point: skill 1 requires skills 2 that requires skills 3, 4, 5 and this skills are almost at their required levels so how much time is needed for skill 1. In reverse order it's necesery to calculate how much time was spend going past skill 3 that must include skills 4 and 5. Ideally the code would be intergrated into existing app.
