Kind of same really. For the past 8 years I've been just "a senior developer". Commercially I've created some CRUD document-processing systems with .NET + web stuff, I've created some apps for smart barcode scanners for warehouses, I've done some touch-only "pretty" apps for corporate reception desks, I've done some mobile apps based on GPS-tracking and QR-sharing, I've done some database-only solutions too (SSIS-based migrations between systems) and many more (desktops, games even).

In my private time I'm having fun with procedural graphics and game-like apps.

Can't say that I'm a domain expert in any of these, but I'm in top 1% earning bracket in Poland (mostly because the general pay in PL is shit and IT is one of the few jobs with "globalized" salary) and that's all I need in life. This approach also has some not often discussed advantages. Like I don't ever worry about job security as there's hundreds of those "CRUD"-making companies all over the world. I've actually went full contractor mode (not paid by the hour, but by completing "specs" (sometimes modules, sometimes entire projects)) in 2019 and I'm booked fully this year (signed contracts by both sides) :V
