Dimitry Sherman
SENIOR SOFTWARE DEVELOPMENT ENGINEER

Dimitry collaborated with the leading fintech companies in the world, implementing solutions for giant like Amazon, Wachovia, and a number of largest Insurance companies in the industry, creating operational efficiencies and constantly bringing innovation to the day-to-day operations. His most recent project spans a number of workflow designs and system implementations, including:

  • Design and implementation of VAT processing tracking and lookup system, to allow recording and lookup the entire lifecycle of a VAT transaction (both business rules application and system failures). The system provides full processing of over 100MM transactions per day, reducing requirements of SDE support by other teams from an average of 4.17 hours a week to 0 hours leveraging tool stack of JSE8, AWS ElasticSearch, SNS, RxJava, KCL.

  • Design of Extensible Orchestrator Service:Created data retrieval, persistence, and caching service to isolate source-of-truth data sources and improve performance for user experience for sellers accessing the application. This layer of the application allowed over 20K sellers in multiple marketplaces to have real-time accesses to thousands of B2B quote requests with UX response times for search, details lookup, and with-in 1200ms SLA. Technology stack used was JSE8, AWS ElasticSearch, SQS, SNS, DynamoDB.

Dmitry architected and implemented a service composition layer with the tooling interface (browser based), allowing for a fast assembly of new interfaces to existing services and data stores. Additional benefit is custom tuned caching isolated from both the client and the underlying services, easier deprecation path for back-end services, and load balancing on per data unit granularity in some cases. This piece of infrastructure reduced new backend service creation and on-boarding from an average of 1 SDE week to 2 SDE days. High severity trouble tickets for services behind this layer were reduced by 12.68%. Implementation was done using JSE 8 and DynamoDB in the AWS fabric.  

Redesign of Secure Messaging Service: Dimitry replaced SquirrelMail with a custom solution, to improve communication tracking and response time between communicating parties. The solution was written using functional programming paradigms. This approach allowed for smaller code base (estimated 37% fewer lines of code) with UT and IT code coverage at 100%. There were zero defects found during UAT, and the first phase of the project was completed with 326 man-hours under budget (1,000 hours were budgeted, for this phase). JSE 8, SpringBoot (with Tomcat) 4.1, Oracle, Gradle were the stack.

Dmitry also led analysis and migration of a .NET based legacy report generation and maintenance application to Grails/Groovy/MongoDB stack based solution. The new solution allowed for progress monitoring and audit, improving in one case report generation speed 840.74% (from 3 hours and 47 minutes to 27 minutes); without restructuring the underlying RDBMS. Exposed report running interface via a RESTful service.
