What I'm looking for

I want to build backend systems that scale reliably—secure auth, efficient data pipelines, and actionable observability. I’m excited to work with cloud-native architecture, distributed systems, and teams that value ownership and measurable impact.

I’m an Associate Software Engineer who ships production-grade backend systems—focused on reliability, security, and performance. At Guidanz Inc, I architected and delivered a custom license management system for BI Connector using a serverless AWS Lambda + PostgreSQL backend, taking key generation, seat enforcement, and feature gating fully in-house.

I also improve resilience under real-world load: I implemented OAuth2 authentication with JWT bearer assertions for Oracle tenants under enforced MFA, eliminated a Redis “thundering herd” with a distributed lock/single-flight approach, and built centralized monitoring with Fluent Bit, Loki, and Grafana to cut incident resolution time by 60%. In parallel, I engineered incremental pipelines (Azure Data Factory and Microsoft Fabric) syncing multi-million-row Oracle Fusion data into Snowflake and SQL Server using watermark-based change tracking—driving a 40% sales increase—while contributing intern work that strengthened performance, deployment stability, and internal tooling (React admin UI).
