As an aspiring game designer, it is super cool to hear from the person who actually designed the adventure I'm running. Interesting to hear that you designed without stats - the thing seems impressively balanced keeping that in mind. I suppose D&D, especially 5E, is a game pretty resistant to balance concerns (the DM can tick up or tick down as necessary), but even so based on play reports most of the fights and other challenges went very smoothly.
Thanks, it is a dream come true to work on D&D! If you are interested in freelancing, keep an ear open for the new organized play program. It has mentioned there will be one (though no official word on when it will begin). When it starts up they will look for authors. Writing for organized play is an excellent way to learn the ropes. You get to work with experienced authors (the admins are almost always incredibly experienced), work with an editor and/or developer (great experience for working with the Wizards process), and then later you can attend a convention and see how what you wrote plays out across many tables. That experience is really invaluable in learning how to shape the player experience. Everything I've done began with my work on organized play and WotC designers liking what I was doing and offering me the opportunity to try writing directly for them.
Once Dragon/Dungeon re-open, that's also an excellent way to show WotC that you can work on a deadline and produce quality work.
It can be a bit tricky to write without stats, but a lot is made easier by the folks at WotC. We might recommend a monster type and WotC can either make a new monster or substitute something with a similar feel. The Wizards team is really fantastic and will usually understand the overall objective and how to ensure the stats they drop in contribute to the experience.
