Über diesen Service

I build telephony software that handles millions of calls a year.


As Backend Team Lead I designed and shipped a high-throughput inbound/outbound dialer and an AI-powered call-tracking & IVR platform used by thousands of concurrent users, with 99.9% uptime.


WHAT I CAN BUILD FOR YOU

Twilio / Telnyx voice & SMS integrations

IVR menus, call routing & queues

Call tracking with marketing source attribution

Call recording, transcription & AI call summaries

Inbound / outbound / power dialers

Conference bridges, voicemail, call forwarding

AI voice agents and real-time audio streaming

Webhooks, Stripe billing and analytics dashboards


TECH

Python, Django, DRF, Celery, Redis, Django Channels, WebSockets, PostgreSQL. Event-driven call lifecycle, atomic locking, failover and audit logging.


Whether you're a call center, marketing agency, clinic or SaaS startup, I'll build voice software that's reliable at scale.


Message me with your use case. I'll suggest the best architecture and estimate your telephony costs.
