Ch Shiv Teja

I’m a Java Full Stack Developer with real-world experience building data engineering platforms and enterprise analytics solutions. At Voziq AI, I architected a production Java-based data lakehouse platform on Axelor Open Suite ERP to deliver enterprise-scale customer analytics and churn intelligence for large datasets.

I build end-to-end CSV ingestion pipelines with robust schema validation, error handling, and versioned table storage in MinIO using Apache Nessie for audit-ready lineage. I also integrated DuckDB and PgDuckDB as in-process analytical engines to run high-speed SQL analytics directly on lakehouse data, and I designed a churn prediction system that extracted signals from PostgreSQL, performed feature engineering in Java, trained a logistic regression model, and persisted batch scoring for business reporting—always with a focus on clean code and meaningful business impact.
