What I'm looking for

I’m looking for a role where I can design and optimize MongoDB at scale—sharding, replica sets, aggregation pipelines—and lead RDBMS-to-NoSQL migrations with strong data governance in AWS/GCP, partnering with teams to deliver reliable performance.

I’m an accomplished MongoDB Developer with 14 years of experience specializing in scalable NoSQL architectures and cloud-native solutions. I focus on the MongoDB ecosystem end-to-end—from advanced schema design, aggregation pipelines, replica sets, and sharding to operational MongoDB Atlas and tooling.

In my recent roles, I’ve designed and optimized high-performance MongoDB document models by balancing embedded vs. normalized structures, enforcing data validation, and applying strategic indexing for demanding read/write patterns. I’ve also orchestrated complex RDBMS-to-MongoDB migrations using Java, Spring Boot microservices, Python, and ETL/ELT pipelines—while establishing strong data governance, lineage, metadata management, and automated remediation rules.

I’m hands-on with large-scale deployments, including HA replica sets for automated failover and sharded clusters for horizontal scalability. Across AWS and GCP, I deploy, monitor, and maintain resilient environments, automate routine administration with JavaScript and Python scripts, and collaborate across teams to bridge traditional RDBMS architectures with modern, scalable MongoDB-based applications.
