05 · System Design — Developer Productivity with Claude Code
Status: Outline. Body fills in the scheduled course week. Voice: principal-level, BFSI-threaded, Apic-calibrated.
What this file is. A structured system design scaffold for the Apic Applied AI Architect prep course.
Purpose
- Design a BFSI internal engineering enablement with repo boundaries, evals, and secure adoption controls.
- Cover discovery questions, business goals, NFRs, HLD, LLD, data flow, integrations, evals, failure modes, cost/latency, rollout, and audience-specific explanation.
- Use the 11-section architecture anatomy from Note 01 as the fill-in structure.
Fill-in structure
- Context: customer, stakeholder, risk, and business goal.
- Architecture/eval decision: the concrete design, rubric, or conversation pattern this file teaches.
- Trade-offs: the rejected alternatives and the condition under which they become reasonable.
- BFSI constraints: data residency, RBAC, PII handling, auditability, latency, cost, and human approval where relevant.
- Strong-Hire answer: the crisp version you can say in an interview without reading notes.
Strong-Hire bar
- Explains the decision in customer language before implementation language.
- Names measurable success criteria and failure modes.
- Shows safety, governance, and eval thinking as part of the architecture, not as afterthoughts.
- Can be defended to an engineering lead, CISO, and executive sponsor.
