## About

Senior Google Cloud Data Engineer with 17\+ years of experience building large\-scale data platforms for global financial institutions — most recently as a core co\-developer of Google Cloud's AI\-first Anti\-Money Laundering \(AML\) platform, built in direct partnership with Google Cloud Product Engineering and taken from Alpha through General Availability\. At HSBC, I architected and operationalized petabyte\-scale ETL/ELT pipelines using BigQuery and Cloud Dataflow \(Apache Beam\), designed temporal data models for Party, Account, and Transaction entities, and delivered measurable outcomes including a 4× improvement in financial crime detection and 60% reduction in false positives\. Beyond detection accuracy, I drove significant BigQuery FinOps wins — optimizing SQL, ingestion pipelines, and slot consumption to reduce cloud infrastructure costs at scale\. My core expertise spans: Data Engineering at Scale: BigQuery, Cloud Dataflow, Dataproc, Cloud Composer, Pub/Sub, GCS AI/ML Platforms: Vertex AI, Kubeflow, Generative AI Infrastructure & DevOps: Terraform, Cloud Build, CI/CD automation Domains: AML / Financial Crime Detection, BFSI, Regulatory Compliance Data Platforms Languages: Python, PySpark, SQL Previously at Accenture \(5 years\), I architected enterprise banking data platforms on the Cloudera stack, leading cross\-functional engineering teams across large\-scale data transformation programs\. I hold Google Cloud Professional certifications \(ML Engineer, and others\) and a TOGAF v9\.1 Enterprise Architecture certification — combining deep technical execution with architecture\-level thinking\. Currently open to Senior/Principal Data Engineer, Data Platform Architect, MLOps Engineer, and Cloud Solutions Architect roles — across Pune, Bangalore, or remotely \(India/Global\)\. 📧 suniljsr@gmail\.com \| 🌐 sunilkumar\-gcp\.netlify\.app

## Work experience

Senior Google Cloud Data Engineer at HSBC, Jan 2025 \- Present · 1 yr 8 mos, Pune District, Core co\-developer of Google Cloud's AI\-first Anti\-Money Laundering \(AML\) platform, collaborating directly with Google Cloud Product Engineering through Alpha to General Availability — one of the most advanced AML detection systems deployed at a global Tier\-1 bank\. Architected and operationalized petabyte\-scale ETL/ELT pipelines using BigQuery and Cloud Dataflow \(Apache Beam\), processing high\-volume banking transaction, party, and account data with enterprise\-grade reliability\. Delivered a 4× improvement in financial crime detection accuracy and 60% reduction in false positives through optimized data modeling and pipeline design\. Led BigQuery FinOps initiatives — tuning complex SQL, partitioning strategies, and slot consumption — achieving measurable cloud infrastructure cost reductions\. Provided technical leadership and GCP best\-practice mentoring across the full project lifecycle, influencing architecture decisions at the platform level\.

Senior Google Cloud Engineer at HSBC Service Delivery \(Polska\), Jan 2023 \- Jan 2025 · 2 yrs 1 mo, Cracow, Continued core contributions to Google's AML AI platform with expanded ownership of BigQuery data modeling and Cloud Dataflow pipeline optimization at petabyte scale\. Designed temporal BigQuery data models using validity\_start\_time / validity\_end\_time patterns for Party, Account, and Transaction entities — enabling point\-in\-time regulatory compliance queries critical for AML investigations\. Built and maintained high\-volume ETL/ELT pipelines using Cloud Dataflow \(Apache Beam\) and Dataproc, processing core banking data models with high availability and fault tolerance\. Drove BigQuery FinOps — optimized ingestion pipelines, SQL complexity, and slot utilization, delivering sustained cloud cost reductions without compromising throughput\. Implemented CI/CD automation using Terraform and Cloud Build, standardizing infrastructure\-as\-code across the data platform and reducing deployment lead times\. Led architecture discussions and mentored engineers on GCP best practices, contributing to team capability uplift across data engineering and platform reliability\.

Google Cloud Engineer at HSBC, Nov 2019 \- Jan 2023 · 3 yrs 3 mos, Hyderabad, Led cloud migration of large\-scale on\-premise Hadoop and Teradata platforms to Google Cloud, modernizing legacy banking data ecosystems into cloud\-native, scalable architectures\. Designed and operationalized petabyte\-scale ETL/ELT pipelines using BigQuery, Cloud Dataflow \(Apache Beam\), and Dataproc for core banking data domains — Party, Transaction, and Account\. Developed BigQuery UDFs for AML model load testing at scale, enabling stress testing of financial crime detection models against high\-volume production\-equivalent datasets\. Optimized SQL, Spark, and ingestion pipelines — significantly reducing BigQuery slot consumption and cloud infrastructure costs through FinOps\-driven engineering\. Provided architectural guidance and mentored engineers across the full data platform lifecycle, from pipeline design through production operations and incident resolution\.

Technology Lead at GSPANN Technologies, Inc, Feb 2019 \- Oct 2019 · 9 mos, Greater Hyderabad Area, • Modernized retail analytics platforms by integrating GCP services with legacy Hadoop ecosystems\. • Reduced batch processing windows by \~30% through Spark optimization\.

Tech Lead at Accenture, Jun 2014 \- Jan 2019 · 4 yrs 8 mos, Pune Area, India, • Architected enterprise banking data platforms using the Cloudera stack\. • Led and mentored teams of engineers across large\-scale data transformation programs\.
