- “We need an independent cloud architecture review.”
- “Our OpenTelemetry / observability stack collects data but does not help decisions.”
- “We need Platform Engineering or developer-platform guidance.”
- “We need SRE / reliability expertise for a critical platform.”
- “We need DevSecOps or software supply-chain expertise.”
- “We need help with SBOM, SLSA, GitOps or FluxCD.”
- “We need to understand cloud costs or FinOps trade-offs.”
- “We need a CTO-level technical review before a migration or major platform decision.”
