About

I am a Backend Engineer at Oracle specializing in high concurrency distributed systems and cloud native infrastructure. Currently, I work on the Oracle BRM Elastic Charging Engine (ECE), a low latency system serving Tier-1 telecom giants like Telia and Telenor. I have a proven track record of ownership, recently serving as the Lead SPOC for a large scale codebase migration to Oracle Cloud Infrastructure (OCI), where I architected CI/CD pipelines and security protocols from the ground up. Beyond infrastructure, I am deeply focused on product stability and performance. I have delivered 50+ product bug resolutions, contributed to 50% reduction in the team’s total backlog. I am also passionate about MLOps and integrating AI into scalable architectures, experience in building RAG based systems, distributed systems and real time observability pipelines.

As a Software Developer I at Oracle, I engineer backend systems for the Oracle BRM Elastic Charging Engine (ECE), a low-latency system for Tier-1 telecom giants like Telia and Telenor. Recently serving as the Lead SPOC for ECE migration to Oracle Cloud Infrastructure (OCI), where I architected secure IAM protocols and automated environment provisioning for 70+ developers, aimed to eliminate ~$100k in annual licensing and infrastructure costs. I have also developed environment-aware Jenkins pipelines and optimized Docker layering techniques, achieving a 40% reduction in the storage footprint. Across the ECE codebase, I have resolved 50+ critical production defects, contributing to a 50% reduction in the team's total backlog.
