About Onkar Limburkar

I\'m a Senior Software Engineer with 11 years of experience architecting and building large-scale, high-performance systems in the AdTech domain — spanning Demand Forecasting, Real-Time Bidding, SSP, DSP, and Adserving platforms.I’ve led complex cloud migrations to AWS, redesigned legacy data pipelines using EMR and Airflow, and driven cost optimization efforts resulting in over 60% infrastructure savings — all while ensuring high availability and zero downtime. My experience includes end-to-end system ownership, from design and implementation to on-call support for production-critical components.I specialize in backend engineering (Java, C++, C), distributed data pipelines, and optimization of compute-heavy workloads. I\'ve worked closely with infra, product, and business teams to deliver features with measurable impact — including compliance-driven filters, forecasting accelerations, and live-event scale readiness.I’ve also mentored engineers, driven cross-team migrations, and contributed to decision-making as part of core component teams with approver responsibilities.Core Strengths: Backend Engineering | Distributed Systems | AWS EMR & Airflow | Cloud Migrations | Cost Optimization | AdTech Infrastructure | Java | C++| System Design | Data Pipelines | Forecasting Engines | Technical Leadership
