Flagship Blueprint
Multi-tenant Reliability + Automation Platform
This is the next “big system” that most clearly signals $300k+ cloud/platform capability: multi-tenant SaaS architecture, async processing, SLOs, guardrails, and automation. It’s intentionally designed so every claim produces receipts (dashboards, alarms, IaC diffs, postmortems, load tests).

What it does (product surface)
- Ingests events (CI runs, test results, deploys, incidents) via API + signed webhooks.
- Normalizes/validates events into a contract-first schema.
- Computes org-level KPIs, SLOs, error budgets, and trendlines.
- Triggers alerts and creates an incident timeline (MTTA/MTTR).
Core architecture
Clients / CI / Webhooks
└─► API Gateway
└─► Ingestion Service
├─ validate + sign + persist
└─ publish event → Queue
Workers
└─► consume events
├─ enrich (repo metadata)
├─ compute KPIs/SLOs
└─ write projections → Postgres
UI (Next.js)
└─► dashboards + audit logs + incidents
Alerts
└─► Slack/Email + on-call simulationSecurity (minimum bar for staff-level credibility)
- Org/user RBAC + audit log + immutable event store
- WAF + rate limiting + request signing + replay protection
- Least-privilege IAM roles for workers and deploys
- Secrets management + OIDC for CI (no long-lived keys)
Reliability + cost signals
- SLOs for API availability/latency + event processing freshness
- Backpressure via queue depth alarms
- Load tests (k6) proving scaling behavior
- Budgets + cost anomaly playbook + guardrails
Milestones (what I’d build in 30/60/90)
0–30 days
- Auth + RBAC + org model
- Event ingestion API + schema validation
- Queue + worker skeleton + dashboards v1
31–60 days
- SLOs + alerts + synthetic monitors
- Audit log + incident timeline
- Terraform environments + promotion gates
61–90 days
- Load tests + scaling evidence
- Cost dashboard + budget guardrails
- Chaos/incident drills + postmortems
