What I'm looking for

I’m seeking a role where I can lead AWS + Databricks platform modernization—Unity Catalog, automation, and CI/CD—while leveraging GenAI tools for reliability and developer productivity. Open to global opportunities with visa sponsorship and relocation.

I’m a Senior / Lead Data Platform Engineer with 9+ years of experience designing, administering, and supporting enterprise-scale data platforms and cloud infrastructure across global enterprises. I focus on platform modernization, infrastructure automation, and building reliable, secure data foundations.

I administer enterprise Databricks platforms that support analytics, AI, and data science workloads. I manage AWS infrastructure (EMR, EC2, S3, IAM, VPC) and use Terraform for deployment consistency, while implementing Unity Catalog, Cluster Policies, and RBAC to strengthen enterprise data governance.

I drive platform reliability through CI/CD-enabled Databricks deployments, performance tuning of Jobs and clusters, and day-to-day 24×7 production support. I also support migrations like Hive Metastore to Unity Catalog, assist data teams with ETL/ELT workflows, and contribute to Lakebase, Data Observability, and OLTP POCs.

I’m passionate about leveraging Generative AI and Agentic AI—specifically Databricks Genie, Databricks Assistant, and AI-assisted engineering—to improve developer productivity, operational efficiency, and platform reliability. I bring a customer-centric mindset, handle incidents/changes via ServiceNow, and collaborate in Agile Scrum/Kanban teams.
