What I'm looking for

I'm looking to build reliable backend services, data platforms, and analytics products where I can improve data freshness, performance, maintainability, and operational ownership for complex business workflows.

I've built backend services, data platforms, and analytics workflows for HCLTech, Monese, and RingIT, turning high-volume operational data into dependable customer-facing and business insights.

At HCLTech, I design Python services and REST APIs, AWS data workflows, and near-real-time and batch ETL pipelines with validation, deduplication, schema controls, and replay-safe processing. I also improve legacy systems incrementally, optimize data models and query patterns, and establish observability through structured logging, metrics, tracing, dashboards, and runbooks.

Previously at Monese, I developed resilient financial-platform services, event-driven processing, and reconciled data pipelines while improving database performance, auditability, and operational support. I focus on fresh, trustworthy data, maintainable services, and practical solutions for complex business workflows.
