Data Architect at Blautech designing Kafka data architectures that cut cross-system sync latency by 30%.

Venezuela

Message

At Blautech, I designed Kafka-based, event-driven data architectures for Telefónica de Venezuela, cutting cross-system sync latency by about 30%. I also improved PostgreSQL query performance and established data synchronization strategies across platforms.

Earlier, I built and maintained ETL workflows at Alivi and worked across software development, architecture, and technical project management in telecom, healthcare, and fintech. I bring experience in data modeling, SQL and PL/SQL, cloud architecture, and DevOps practices, and I'm deepening my work with Python for large-scale data processing.
