Amando Martínez Vivancos

Joined as Software Engineer (Oct 2022) · promoted to Senior in January 2026

• Built the news intelligence pipeline that ingests, deduplicates, clusters and classifies 20,000+ news items a day with LLMs on Airflow 3 over Kubernetes — and cut its annual LLM bill by 85% — a six-figure sum down to a five-figure one — by ordering stages by cost and moving them to smaller models once evaluation showed no quality loss.
• Built the regulatory pipeline’s discovery layer: a generator that writes fetchers behind a seven-stage deterministic harness and a human review, plus the health job that detects silent breakage and hands the worst sources back to it. 193 of ~290 catalogued sources across 130 jurisdictions are covered by 153 modules, and report processing takes the legal team 70% less time.
• Shipped the application’s user management and authentication system, and the resource-sharing layer that makes live collaborative work possible across accounts.
• Introduced and spread the practices a 20-developer engineering org now works by: DDD, hexagonal architecture, TDD, shared linting and formatting standards, and proper database connection-pool management.
• Led the adoption of AI-assisted development — agents and evaluation harnesses wired into pipelines, repositories and delivery processes, not just editor autocomplete.
• Owns observability for the systems I build: Grafana dashboards and Sentry alerting, so failures surface as signal rather than as a customer email.
• Works directly with stakeholders to turn customer needs into features, from scoping through to production.
