These ten projects mirror what teams ship daily and let recruiters see real impact; build each with tests, CI/CD, containerization, observability, and a short case study with metrics like latency, errors, or cost.
1) Auth-enabled API with RBAC
- Build a REST/GraphQL service with signup/login, roles/permissions, validation, pagination, rate limits, and consistent error models.
- Evidence to show: OpenAPI docs, integration tests, p95 latency, and one optimization (indexing/caching) with before/after metrics.
2) Payments or booking workflow (idempotency + queue)
- Simulate retries, outbox pattern, and eventual consistency; include a small cache and performance note.
- Evidence to show: correctness under failure, idempotency keys, and a 2‑minute demo of a retry scenario.
3) CDC → warehouse → BI dashboard
- Ingest mock OLTP changes, transform to star schema, add data quality tests, and publish a KPI dashboard (Tableau/Power BI).
- Evidence to show: lineage diagram, SLA adherence, and a one‑page brief with decisions and caveats.
4) Streaming analytics with alerts
- Consume events, compute windowed aggregates, and trigger anomaly alerts; expose a minimal API or dashboard.
- Evidence to show: precision/recall on a labeled window and alert latency under load.
5) AI‑powered RAG application
- Ingest domain docs, test chunking/embedding strategies, design prompts, and add safety/refusal rules with offline evaluation.
- Evidence to show: answer‑quality eval set, latency/cost per query, and “failure modes and fixes” notes.
6) DevOps/SRE platform slice
- Provision infra with IaC, build CI/CD with artifact signing and policy checks, and implement blue/green or canary releases.
- Evidence to show: SLO dashboard (p95/p99, error rate), budget alerts, and a documented rollback drill with MTTR.
7) Hardened web app (AppSec)
- Secrets management, parameterized queries, SBOM + dependency scans, least‑privilege IAM, and secure headers/CSP.
- Evidence to show: CI failing on unsafe changes, a mini threat model, and a post‑fix security note.
8) Cost‑aware cloud refactor
- Take a simple service and reduce cost via right‑sizing, autoscaling, storage tiers, and reserved/spot patterns without breaking SLOs.
- Evidence to show: monthly cost reduction with graphs and unchanged reliability/performance.
9) Business analytics dashboard with narrative
- Build a decision‑ready dashboard (sales, retention, churn drivers) with filters, segments, and a concise executive summary.
- Evidence to show: three actionable insights and one experiment or metric you’d run next.
10) Mobile or accessible frontend app
- Offline‑first notes/tasks with sync and conflict resolution, or an accessible dashboard with Lighthouse 90+ and a11y checks.
- Evidence to show: startup time, sync conflict handling, and accessibility audit output.
How to present them so recruiters care
- Featured artifacts: repo with one‑command setup, tests, CI badge, Docker/devcontainer; 2–4 minute demo; README with diagram, metrics, and trade‑offs.
- One‑line resume bullets with numbers: “Cut p95 latency 38% via indexing/caching,” “Reduced monthly cloud cost 22% with autoscaling + storage tiers,” “Rolled back failed canary in 90s; MTTR 12m.”
- Depth over breadth: 3–5 polished projects beat 10 shallow clones; integrate AI thoughtfully and show business impact.
4‑week execution plan (one flagship)
- Week 1: Core feature + DB schema, tests, CI, Docker, baseline metrics.
- Week 2: Observability, SLO, one performance fix; record a quick demo.
- Week 3: Security pass (secrets, scans, SBOM), deploy with IaC; run canary/rollback drill.
- Week 4: Case study write‑up with before/after graphs; request one external code review and publish on LinkedIn.
Build the right problems, measure results, and package them professionally; this combination gets attention and accelerates hiring in 2025.
