About

Senior Software Engineer @ Sony PlayStation — architecting ad delivery systems for 50M+ users. I build high-performance microservices, end-to-end data pipelines, and LLM-driven agentic workflows that power real-time monetization at scale. Previously @ Epicor, scaled ERP systems by 25%, cut deployment time by 30%, and owned CI/CD infrastructure across distributed teams. 🔧 Python • Microservices • PySpark • Databricks • Snowflake • AWS • FastAPI • CI/CD

Work experience

Senior Software Engineer at Sony India Software Centre, Jul 2025 - Present · 1 yr 2 mos, Bengaluru, Karnataka, India, Designed and deployed multi-tenant audience and ad-delivery microservices in Python (FastAPI) into PlayStation Store, processing live traffic for 50M+ active users globally. Built asynchronous distributed backend systems using Python and PostgreSQL, optimizing high-concurrency database reads/writes for real-time ad campaign allocation under peak load. Architected high-throughput REST APIs and gRPC contract interfaces, reducing partner onboarding friction by 25% and accelerating system validation cycles. Built fault-tolerant ETL pipelines using PySpark on Databricks, routing structured data to AWS S3 and loading analytics schemas into Snowflake for business intelligence and monetization reporting. Provisioned sub-second real-time aggregation workers with Kafka and Redis, maintaining high availability and low-latency processing during Peak Active Hour traffic spikes. Optimized Jenkins CI/CD pipelines with Docker and Kubernetes, standardizing staging environments across microservices and achieving zero-downtime deployments. Built automated LLM-driven evaluation and regression loops using LangChain to enforce data quality constraints across live pipelines, improving output reliability by 30%. Monitored system health using Prometheus and Grafana, setting up alerting dashboards to detect and resolve latency anomalies before user impact.

Product Developer at Epicor, Oct 2024 - Jul 2025 · 10 mos, Bengaluru, Karnataka, India, Decomposed legacy monolithic ERP services into independent Python and Django microservices, increasing processing scalability and compute capacity by 25%. Designed and built secure REST API modules for partner data distribution, driving 15% increase in product feature adoption and reducing integration turnaround time. Revamped Jenkins CI/CD workflows, reducing build validation time and test bottlenecks by 30%, enabling faster and more reliable releases. Containerized services with Docker orchestrated via Kubernetes, eliminating environment mismatches and cutting infrastructure-related deployment failures by 30%. Diagnosed slow query plans and added missing PostgreSQL indexes, reducing service-call latency and improving backend response times by 25%. Wrote Python automation scripts to simulate enterprise load and mock system dependencies, shrinking regression test cycles from hours to under 15 minutes. Integrated Prometheus metrics and Grafana dashboards for real-time service monitoring, enabling proactive detection of performance regressions.
