Summary
👤
Senior🎓
Top SchoolJaime Valero is a Principal Software Engineer based in London with a decade of experience designing and shipping data-intensive, cloud-native systems primarily on AWS. He has led end-to-end builds of production data platforms—ingesting billions of records, running Kubernetes-based Python services, and managing infrastructure as code with Terraform. Jaime blends data engineering (Airflow, Kafka) with backend API development (FastAPI, SQLAlchemy) and observability stacks he architected himself (Prometheus/Grafana, ELK). As a hands-on lead he’s scaled small teams, owned IAM/VPC/security, and turned complex race-data requirements into a 300GB+ analytics lake and multiple consumer products. Comfortable across databases from Redshift and BigQuery to Druid and InfluxDB, he also drives migrations and format optimizations (JSON→Parquet) to improve cost and performance. His GitHub (JaimeOverflow) signals a curious builder mentality that complements a pragmatic, production-first approach.
