15 years across embedded Linux edge systems and AWS cloud infrastructure. End-to-end platform ownership spanning C/C++ devices deployed in 120+ countries to a multi-account AWS environment serving millions of requests per day.
A real-time prompting system for executives and speakers — transcribes the conversation live, retrieves the exact fact you need from your own knowledge base, and surfaces it on your screen within half a second so you respond calmly instead of freezing.
Proof of concept built in 2 days. Zero-latency teleprompter on a single Mac. Apple Silicon NPU transcription, vector-semantic RAG (pure numpy, no external DB), and a multi-role web UI where staff inject tactical cues into the speaker's display in under 0.5s.
Industry-aligned split across four tiers, each with its own repo and ownership boundary:
| Tier | Industry name | Stack | Repo |
|---|---|---|---|
| Account fabric | Landing Zone (AWS Control Tower) | Organizations · OUs · SCPs · Identity Center · GitHub OIDC · security baseline | aegis-aws-landing-zone |
| Platform | Platform engineering / paved road / IDP | EKS + Karpenter · ArgoCD · observability (extracted from landing-zone per ADR-033) | aegis-platform |
| Workload — app | Application repo | C++ + whisper.cpp (gRPC) · Go BFF gateway · TypeScript React · dual-mode LAN/Cloud | aegis-core |
| Workload — deploy | Config repo (two-repo GitOps, Weaveworks) | K8s manifests for the application | aegis-core-deploy |
End-to-end GitOps loop: CI in the app repo builds + pushes the image to ECR, commits the new tag cross-repo into the deploy repo, ArgoCD in the platform tier reconciles. Architecture Decision Records document every trade-off plus a running incident postmortem log.
