As CTO I owned the technical strategy and the whole delivery cycle: service architecture, Node.js/TypeScript backends, Vue/Nuxt frontends and integration with OpenAI and other LLM providers. The platform takes leads from web forms and chats, runs voice and text agents, attaches an AI summary to every conversation and passes results to the CRM. Infrastructure lives on AWS — VPC, EKS, RDS, ECR — described in Terraform modules, with GCP and Cloudflare alongside. I also ran hiring, code review and releases.
