Headless FastAPI REST API for corporate travel. Relational PostgreSQL database, Redis, immutable double-entry ledger, Decimal money. Production deployment with interactive docs.

• Redis idempotency and PostgreSQL row locks (FOR UPDATE) so a retried confirm cannot double-post. Asynchronous processing via HTTP 202 background jobs.
• Receipt extraction with PydanticAI and Groq. Closed schema extra=forbid as a guardrail against prompt injection; structured LLM outputs are validated in code before any database write. The model cannot approve or pay.
• Hybrid retrieval (RAG-style): SQL prefilter, RapidFuzz, hashed-token vectors, Reciprocal Rank Fusion. Unit testing with pytest, CI/CD, Prometheus observability.

Co-developed B2B SaaS. Batch lookup of Spanish companies by razón social against official BORME records. FastAPI, Celery distributed workflows, Redis, PostgreSQL, React. Original file columns are preserved on export.

• Company-name column inference, atomic Redis quotas, HMAC download tokens, Stripe test Checkout, waitlist persistence, GitHub Actions CI.
• Legal-form mismatch (S.L. vs S.A.) stays REVISION_SUGERIDA.
