/services/app-developmentEngineering approach
Arekan mapped trust boundaries, data flows, and failure modes before writing code or rules. We ran staged pilots with rollback plans, defined SLOs for detection or retrieval quality, and aligned deliverables to audit evidence requirements.
Solution
We implemented production-ready components using AWS, Terraform, RDS with infrastructure-as-code, monitored rollouts, and handover runbooks. Customer identities remain confidential; this case reflects a composite of anonymized enterprise engagements.
Implementation process
- 1.Discovery and asset inventory
- 2.Architecture design and threat modeling
- 3.Pilot implementation in staging
- 4.Production rollout with canary validation
- 5.Handover, training, and continuous improvement roadmap
