Within Securities Financing, I have worked on various greenfield projects for architecting, designing and developing solutions with Cloud-First approach. Developing cloud-native applications as well as hybrid on-premise/on-cloud applications. One of the first projects was a cloud native MIS system, for which I developed number of stateless Java/Spring Boot based microservices and using BigQuery, Cloud Storage, Pub/Sub, Apache Beam Dataflow and Data Studio offerings of GCP as well as setting up per application service accounts, ensuring application access conforms to least-privilege, recycling keys etc. Another project, a position keeping system is a hybrid system with dozens of adapters, each with microservices spanning across on-premise/Cloud Compute and utilising Hazelcast for distributed caching and work distribution and various cloud technologies such as Cloud SQL, Compute, Managed Instance Groups, Autoscaling, Cloud Storage, Pub/Sub, Secret Manager, VPC firewall rules. Also, a significant DevOps focus: utilising Terraform quite heavily and built terraform modules which create the entire infrastructure for given adapter set: CloudSQL instance, buckets, MIGs, LB, health check, DNS entry with just a minimal information needed to be provided and ensuring consistency of Infrastructure across dev lifecycle as well as production/dr and across multiple adapters; building Jenkins pipelines for continuous deployment onto GCP easing the path for teams owning other adapters to migrate to GCP. Technologies: Java 8, Microservices, various Java 8 concurrency and low latency constructs, Hazelcast based Distributed Processing, Spring Boot, Docker/Kubernetes, Terraform, Cloud Storage, BigQuery, Cloud Pub/ Sub, Cloud Functions, Dataflow, Apache Beam, Cloud SQL, Git, Jenkins Declarative Pipelines,

• Integration of Mifid II reporting vendor solution with RBC VOIX trading system

• Post Go-Live, Given ownership of entire vendor developed stack and primary responsibility of bringing code and IP in-house, and responsibility for the vendor solution deployed on GCP.

• Designing, Implementing acceptable DevOps solution for building components and deploying them to GCP, conversation with internal stakeholders such as Risk Team to enable cloud deployments

• Architecture and Delivery responsibility for further business requirements and stabilisation of vendor developed stack, as well as optimise use of GCP platform; liasing with RBC RTB and Infrastructure teams to integrate RBC build process with GCP deployment satisfying RBC's policies

• Solution Architecture and full design/delivery responsibility for new reporting functionality for data already in BigQuery. Various POCs for code improvements, new technologies, architectural changes. Technologies: Java 8, Spring 5, Microservices, Maven, Project Lombok, Swagger, Git, Solace, RabbitMQ, Docker, Kubernetes, Google Cloud Platform (BigQuery, GCS, Cloud Datastore, Google Kubernetes Engine, GCE, Apache Beam/Cloud Dataflow, Cloud SQL, Stackdriver, Cloud Functions, Synchronous Pub/Sub), reactive programming using Spring Webflux, Grafana/Prometheus for application monitoring, Jenkins deployment on Compute VM
