About this gig

Stop struggling with dropped calls and activation errors. Whether youre a startup or an established carrier, you need a platform that just works. I specialize in high-performance Linphone customization and GSMA-compliant eSIM integration.


What I Do Best:

  • Linphone SDK Mastery: Custom-built softphones for iOS, Android, & Desktop.
  • eSIM Evolution: Full SM-DP+ integration for seamless remote provisioning.
  • The "Big Fix": I kill one-way audio, NAT/STUN issues, and Push Notification lag.
  • Backend Power: Scalable Flexisip, Asterisk, and API-driven architecture.


Why Hire Me? I dont just "code"I solve. From TLS/SRTP encryption to QR-code provisioning, I ensure your app is secure, scalable, and ready.


Don't let technical bugs stall your growth. Lets build a communication powerhouse.
