Open-source multi-agent system for EU public tenders (GitHub: tender-agent). Built with LangGraph and Grok (xAI): analysis, strategy contract, master outline YAML, chapter-by-chapter drafting with curated merge, fragment and coherence review, and human-in-the-loop gates — producing submission-ready proposals with Obsidian-compatible workflows.
Outcome: CERV-scale chapter pipeline with auditable gates; primary flow documented in the repo README.

Platform engineering with observability as the operating backbone — metrics, logs, and health signals across infrastructure and data pipelines before optimization or intervention. The infra layer combines VPC/network design, Terraform modules, Docker Compose (App → PgBouncer → Postgres), backup/restore, CI/CD, and FinOps cost controls with CloudWatch, Prometheus, Grafana, and Loki. The data pool pipeline adds traceable ETL: OpenStreetMap geospatial data and in-situ measurements via GeoPandas/Pandas, schema unification, quality checks, and validated exports for downstream product layers.
Outcome: Observable, finance-steerable platform foundation with correlated infra and data signals plus a validated geospatial data pool.
