Scale with confidence

Break free from voice API unreliability.

Vendors like VAPI give you a fast start, but they also come with rate limits, outages, and limited features. When it's time to scale, owning your AI voice infrastructure unlocks reliable, profitable growth.

BUILD for Scale

Why AWS versus a third party voice API?

Own your voice infrastructure with the flexibility, control, and scale that vendors like VAPI can't provide.

Production deployment with zero downtime

Tech 42 handles the complete migration so your voice agent moves to AWS without disrupting your business.

Phase 1
Proof-of-Concept (6-8 wks)
-> Assessment
We analyze your existing architecture and produce a migration blueprint and cost model tailored to your setup.
-> Design
We build a production-ready AWS solution architecture before a single line changes in your live environment.
-> Proof-of-Concept
Pilot deployment with your core features running on AWS. You validate it before we go further.
Phase 2
Production (6-8 wks)
-> Build
Full infrastructure and agent deployment on
AWS at feature parity or better, including full observability.
-> Migration
Parallel testing and a zero-downtime cutover. Your customers won't notice the switch.
-> Handoff
Knowledge transfer and training so your team fully owns the platform when we're done.

RESULTS That Speak for Themselves

Build AI voice that's ready for scale

Tech 42 is your embedded AI engineering partner, here to make your vision reality.

Tech 42 was a strong partner in helping HealthNote migrate our AI Medical Receptionist from a VAPI-based system to a fully AWS-native architecture, building on prior assessment and proof-of-concept phases to deliver a production-ready deployment across our healthcare client base.

The team delivered a GitHub Actions CI/CD pipeline for staging and production deployment with rollback functionality, multi-channel voice agent support across voice, SMS, and web, and Telnyx-based failover to address a key redundancy requirement. They also deployed Langfuse V3 via Terraform with HIPAA-aligned security controls — AWS KMS encryption, private VPCs, IAM least-privilege, CloudTrail logging, and automated RDS backup with recovery documentation — along with a Bedrock Knowledge Base RAG evaluation report, an LLM-as-judge evaluation framework, and an example MCP server implementation.

Throughout the engagement, the Tech 42 team went beyond the initial scope of work to help us achieve our proof-of-concept goals, collaborating closely with our engineers to ensure the system was not only delivered but positioned for successful production use.

The team delivered thorough documentation including an infrastructure architecture diagram, a full Terraform resource index, and step-by-step deployment instructions, along with a recorded live demonstration that left our engineers equipped to manage the infrastructure independently.

The team was precise, documentation quality was high, and issues were addressed promptly. We appreciate the partnership and the work Tech 42 brought to this engagement — it has put us in a meaningfully stronger position as we move toward full productionization."
