Telephony platforms fail in the infrastructure layer, and that is the layer most VoIP and SIP specialists on this platform do not work in. I am a cloud infrastructure engineer holding AWS Certified DevOps Engineer - Professional and AWS Certified Solutions Architect - Professional. I build and operate the AWS platform that voice workloads run on, and I build all of it in Terraform so the environment is reproducible, reviewable and recoverable. Where I work: Amazon Chime SDK - Voice Connector and SIP Media Applications, Lambda call-control functions, PCI-scoped DTMF capture, SRTP and call-recording boundaries, CloudWatch and CloudTrail evidence for audit. SIP and VoIP infrastructure - call routing and failover paths, trunk and DID configuration, media path design, latency and packet-loss investigation, capacity planning. WebRTC and low-latency media - TURN and STUN infrastructure, media services on Kubernetes with autoscaling, network policy and TLS termination. The AWS foundation underneath all of it - private VPC networking, least-privilege IAM, KMS encryption, API Gateway, Prometheus and Grafana, and Terraform for every resource. Why this matters for your voice platform: Most voice work available here is either PBX administration or no-code agent assembly on a hosted platform. Neither gives you infrastructure as code, an environment you can rebuild from scratch, a tested failover path, or an audit trail that survives a compliance review. That is the part I do, and it is the part that decides whether your call quality and your uptime hold under load. How I work: Every change lands as Terraform. Blast radius is understood before the apply, not after. You get the code, the runbook and the evidence that it works, not just a fixed environment. If you are running or building on Amazon Chime SDK, a SIP trunk, a WebRTC media path, or a contact-centre platform on AWS, and you need the infrastructure engineered rather than configured, send me the architecture and the symptom and I will tell you where I would start.
