Ask HN: How did you land your first projects as a solo engineer/consultant?
I’ve spent roughly the last decade and some change as a software engineer, and recently decided to start a solo consultancy. I’m focused on helping SMEs sort out the messy back-office parts of the business: spreadsheet glue, brittle internal workflows, poor reporting, awkward integrations, backend/platform problems, and AI workflows that need to do real work rather than just look good in a demo. I’m not really interested in becoming a generic agency. I’d rather work with businesses that already feel operational pain and need someone technical to help untangle it properly. For those of you who’ve made this jump: * how did you get your first real project? * what kind of outreach actually worked? * did your first few clients come from network, content, cold outreach, partnerships, subcontracting, or somewhere else? Also, if anyone knows SMEs or operators dealing with this sort of mess, I’d be glad to chat. As a gesture of goodwill, I’m offering the first 5 clients 10 hours free to help ge

Yojam: a macOS default-browser shim that routes URLs through a rule engine
Author here. Yojam replaces the default browser on macOS so every URL - clicks, Finder .webloc/.inetloc/.url files, Handoff, AirDrop, Share and Services menus, Safari/Chromium/Firefox extensions, and a yojam:// scheme - runs through one pipeline: global regex rewrites, tracking-parameter scrubbing, rule matching, per-browser rewrites, then open-or-pick. Technically interesting bits if you want to pick them apart: Rules can target specific browser profiles, not just bundle IDs. For Chromium this means shelling out with --profile-directory; for Firefox, -P with the profile name; for Safari/Orion, AppleScript because there's no profile CLI (because of course there isn't). Source-app filtering uses real originating bundle IDs where macOS actually gives them to us, and synthetic sentinels (com.yojam.source.handoff and friends) where it doesn't. Rules can key on either. The Share Extension, Safari Web Extension, and native messaging host are separate Xcode targets sharing an App Group contai
