About Adriano

Adriano V.Status: Offline
Senior Backend & Data Engineer | FastAPI + Kafka + ETL Pipelines
5.0  (2 reviews)
Ichenhausen, Germany - 10:14 pm local time
I help SaaS and enterprise teams build reliable, high-performance backends and data pipelines that actually scale.

20+ years shipping production systems. I specialize in:
• FastAPI microservices & real-time Kafka streaming
• Complex ETL/ELT pipelines (Oracle → PostgreSQL/BigQuery)
• SQL query tuning & performance rescues (12s → 300ms is normal)
• API integrations (Stripe, PayPal, ERP, custom REST)
• Docker + Azure/GCP cloud deployments

Recent wins on Upwork:
• Payment processor integration delivered in 8 days (5.0 rating, June 2024)
• Backend systems for Best Secret GmbH & Oetker Digital (Kafka + Java + PostgreSQL)

If your current setup is slow, breaking, or you need a new pipeline yesterday — I respond same day and usually ship working prototypes in 48–72 hours.
