The best way to reach me is LinkedIn - I check it regularly and it's where work-related messages belong. If you're writing about Vercel, consulting, or anything engineering-shaped, start there and say what you're after in the first message; you'll get a faster reply.
GitHub is where my open source and side projects live. If you've found a bug on this site or want to talk about something I've built, an issue or discussion there works well.
Instagram is the casual channel - travel, training, music. Fine for a hello, not the place for work enquiries.
If you want to recommend a place - a restaurant, bar, hotel, or anything else worth a detour - every city page under /recs has a small form in the "On the list" section. Anything sent there lands directly in my inbox, and the good ones end up on the site.
