   Working as a Senior Backend & Data Platform Engineer within Market Risk and Regulatory Analytics, I contribute to Issuer Risk Calculation platforms supporting both standardized and Internal Models Approach (IMA) regulatory frameworks. The platform processes high-volume financial risk data and is critical to capital calculations, P&L attribution, and risk data aggregation.My role spans on-premise and cloud-based data processing systems, with primary focus on scalability, performance optimization, and production stability across the risk analytics stack.On the on-premise platform, I developed and enhanced a Spring Boot–based backend application used for high-performance risk computations. Apache Spark is leveraged for large-scale post-processing and aggregation of risk metrics, supporting enterprise-wide Risk Data Aggregation initiatives. I worked extensively on Spark job optimization, including partitioning strategies, join optimization, shuffle reduction, and memory tuning to improve execution time and throughput. Oracle Database is used for transactional data, with HDFS providing scalable distributed storage for large datasets.On the cloud platform, I contributed to DRC-IMA pipelines implemented using Spark on Azure Databricks, supporting regulatory capital analytics. I designed and implemented ETL pipelines using Azure Data Factory (ADF) to ingest data from Oracle into ADLS Gen2, enabling scalable cloud processing. I worked on Databricks workloads involving Delta Lake, focusing on reliable data processing, schema evolution, and performance tuning, along with monitoring and production issue resolution.Across both platforms, I work closely with risk analysts and stakeholders to translate regulatory requirements into robust, scalable technical solutions, bridging backend engineering and data engineering concerns.Domain Expertise: Market Risk, Regulatory Risk Analytics, Issuer Risk, Capital Calculations, P&L Attribution, Risk Data Aggregation.
