Freelance Development

Beyond publishing, hands-on engineering.

Alongside its own games, EmberTwist Sanctuary takes on focused development work for other apps and teams — the practical, unglamorous fixes that keep a product running well.

01

API integration

Connecting apps to third-party services and payment, analytics, or backend APIs — wired up cleanly and tested end to end.

02

Bug fixing & error resolution

Tracking down crashes, broken flows, and inconsistent behavior, then resolving the root cause rather than patching symptoms.

03

Security hardening

Reviewing and tightening how an app handles data, requests, and permissions to reduce exposure to common vulnerabilities.

04

Performance optimization

Cutting load times and smoothing rough interactions so the app feels fast on real devices, not just in testing.
