About

Senior Software Engineer / SMTS at Oracle OCI with 5+ years of experience building scalable backend, distributed, and cloud-native systems across enterprise and fintech products. At Oracle, I work across backend architecture, high-volume data processing, cloud migration, reliability, and automation. I designed Java-based migration and validation APIs for large customer/workload datasets with memory-efficient processing to keep JVM usage controlled during production runs. I also worked on Apache Kafka streaming migration, solving connectivity challenges involving broker routing, tunneling, DNS mapping, SASL/SSL, certificates, and Java truststores. My work spans production reliability and platform engineering, including identifying 28 production-risk areas across resource lifecycle management, HTTP clients, executors, SQL safety, logging, diagnostics, and testability. I also contributed to OCI tenancy migration initiatives, built configuration-driven architecture that reduced repeated UI update cycles by ~80%, and delivered platform improvements that increased operational efficiency by ~30%. My broader experience includes AI-assisted business workflows, OCI BYOK/security architecture, Grafana observability, workload automation, operational reporting, and cross-system integrations. Before Oracle, I was a core engineer at Credit Saison India, where I owned 7+ repositories and helped build the Collections Platform end to end. I developed repayment flows, payment integrations, and UPI-based systems handling 3M+ records, optimized APIs by up to 60%, built automation that eliminated thousands of manual entries per cycle, and developed AWS data pipelines using Lambda, Redshift, Athena, and AWS Wrangler. I enjoy solving problems around distributed systems, scalability, system design, performance, reliability, and clean architecture, backed by 1600+ DSA problems solved. Core: Java • Spring Boot • Distributed Systems • Kafka • Microservices • REST APIs • System Design • OCI • AWS • SQL • Observability Open to Senior Software Engineer, Backend, Distributed Systems, and Platform Engineering opportunities with international relocation across APAC, Australia, Canada, and Europe.
