FDE Portfolio Project Ideas (Ranked by Hiring Signal)

How to read this list

Ranked by how often the underlying skill appears in real FDE work. One project done with the full delivery arc (brief → build → deploy story → measurement) beats three half-built demos. Format requirements: see the portfolio guide.

1. Messy-data integrator (signal: ★★★★★)

Scope: two inconsistent datasets → idempotent reconciliation with quarantine report. Proves: data fluency, integrity thinking, operational reporting. Write-up must include: the error taxonomy and one week of "what broke" journaling.

2. Permission-aware retrieval assistant (★★★★★)

Scope: RAG over documents with role-based ACL, enforced pre-retrieval; unauthorized-access test suite; grounded answers with citations. Proves: 2026's hottest stack with security instinct - the rarest combo. Write-up must include: the attack cases you tested and failed to break.

3. Flaky-upstream survivor (★★★★☆)

Scope: API client surviving 15% failure + duplicate webhooks: backoff, idempotency, DLQ, runbook. Proves: production reliability judgment. Write-up must include: the failure-injection table and how each was survived.

4. Human-approval workflow (★★★★☆)

Scope: AI drafts, human approves, audit trail; reversal path included. Proves: agent-pattern maturity, audit thinking. Write-up must include: the approval UX decision and why (friction vs safety).

5. "AI was the wrong tool" case study (★★★★☆)

Scope: deterministic problem solved with rules; honest comparison vs an LLM approach (accuracy, cost, latency). Proves: judgment and honesty - employers remember this one. Write-up must include: the comparison table and where AI would become right (data scale, variance).

What to skip

Todo apps, tutorial clones, dashboard-only projects, anything whose README apologizes for hardcoding. And skip the sixth project: polish one instead.
