I build and fix call-center phone systems: VICIdial, FreeSWITCH and Asterisk dialers, SIP trunks, WebRTC softphones, and AI voice agents that answer or place calls. I recently built DialForge, a cloud predictive dialer from scratch (Go, PostgreSQL, FreeSWITCH): predictive pacing, answering-machine detection, abandoned-call handling, multi-tenant isolation, and an hour-long soak test at 50 concurrent calls. Behind that is 8+ years of backend work for US companies: I led a multi-tenant Laravel SaaS on AWS (Revvlab) and connected 7 third-party systems into one sales workflow (BetterEarth). That means your dialer won't sit alone: I'll wire it into your CRM, lead sources and reporting. What I do: • VICIdial install, configuration, custom campaigns, reports and API integrations • FreeSWITCH / Asterisk setup, dial plans, IVRs and call recording • SIP trunks, carrier setup, one-way audio, NAT and call-quality fixes • Predictive and progressive dialing, answering-machine detection, pacing tuning • AI voice agents: speech-to-text, LLM and text-to-speech on real phone lines • CRM and lead integrations through REST APIs and webhooks • Compliance basics: DNC lists, calling-hour windows, consent logs Also available for Python, PHP/Laravel and Node.js backend work, API integrations and automation. Ongoing maintenance or a one-off fix, both welcome. Send me what's broken or what you want built, and I'll reply with a clear plan.
