DBSync
Cross-database schema comparison, hash-based row validation, migration tooling, and CDC pipelines when engines or schemas differ.
View systemRamakrishnan Ayyappan · Database Architect
Architecting resilient databases, scaling real-time data pipelines, and building AI systems that move, scale, and explain themselves.
I unite core database architecture, production data engineering, and intelligent AI operations. I specialize in designing high-performance schemas, cross-database synchronization, and real-time CDC streaming pipelines (Kafka, Debezium, Airflow) that move data seamlessly at scale. Combining deep database internals with enterprise observability, I build AI-powered operations, schema-aware AI agents, and custom SaaS tools so teams can query systems, automate work, and ship products—not just wrap a chatbot around a database.

AI Costs Are the New Cloud Bill
Most AI ops systems route every task through one expensive model. The cheaper path is task-model fit: rules, cache, small models, then escalate.

Architecture, migration planning, CDC design, or AI ops—send a short note and we can map the path from constraints to a working system.
