  • REALCompute® Engine Framework

    Responsible for management, architecture design and coding of Altisource Lab’s REALCompute® Engine Framework (RCE); the basis for our next generation debt servicing platform. RCE is a high-performance, distributed, horizontally-scalable, fault-tolerant and modular cloud-based CQRS/ES application framework based on the tenets of the Reactive Manifesto. The project codifies common CQRS/ES and DDD principals and simplifies the life cycle of persistent actors in an Akka cluster. A Scala and Java…

    Responsible for management, architecture design and coding of Altisource Lab’s REALCompute® Engine Framework (RCE); the basis for our next generation debt servicing platform. RCE is a high-performance, distributed, horizontally-scalable, fault-tolerant and modular cloud-based CQRS/ES application framework based on the tenets of the Reactive Manifesto. The project codifies common CQRS/ES and DDD principals and simplifies the life cycle of persistent actors in an Akka cluster. A Scala and Java API are provided along with a reference application to enable the teams to see how to use it in either Scala (Spray / Akka) or Java (Jetty / Spring / Akka) environment.

    Key Technologies and Principles:
    • Scala
    • Akka
    • Cassandra
    • Spark
    • Distributed Systems
    • Cloud Computing
    • Event Sourcing
    • CQRS - Command Query Responsibility Segregation
    • Docker
    • Continuous Integration

  • REALServicing® - Next-Gen Debt Servicing Platform

    -

    Develop next-generation Debt Servicing platform using Command Query Responsibility Segregation (CQRS), Akka, Event Sourcing (ES), Domain Driven Design (DDD) principals with AngularJS for the UI with polyglot persistent model based on Cassandra, MongoDB and MySQL. Responsible for the architecture, design, development and implementation of the underlying services and abstraction to enable new team members to get up and running quickly. Manage distributed agile engineering team developing complex…

    Develop next-generation Debt Servicing platform using Command Query Responsibility Segregation (CQRS), Akka, Event Sourcing (ES), Domain Driven Design (DDD) principals with AngularJS for the UI with polyglot persistent model based on Cassandra, MongoDB and MySQL. Responsible for the architecture, design, development and implementation of the underlying services and abstraction to enable new team members to get up and running quickly. Manage distributed agile engineering team developing complex optimization based solutions in a highly concurrent big data environment.

  • REALServicing® Data Replication and Synchronization Platform

    -

    Designed and participated in the implementation of a distributed, horizontally-scalable, near real-time data replication and synchronization platform. (Similar in aim to LinkedIn's DataBus.) The core service, Replication Engine, is a set of Spring Integration (SI) components that read from RabbitMQ, deserialize the payload, and ensures that transactions are applied in the correct order with standard EIP resequencer. The system scales using loosely associated nodes tied together with message…

    Designed and participated in the implementation of a distributed, horizontally-scalable, near real-time data replication and synchronization platform. (Similar in aim to LinkedIn's DataBus.) The core service, Replication Engine, is a set of Spring Integration (SI) components that read from RabbitMQ, deserialize the payload, and ensures that transactions are applied in the correct order with standard EIP resequencer. The system scales using loosely associated nodes tied together with message queues. Data is synchronized between heterogeneous stores using STOMP.

    Key Technologies:
    • Java
    • Tomcat
    • Spring
    • Spring Integration
    • RabbitMQ
