PROFESSIONAL EXPERIENCE

Technical Lead, Excella, Virginia, VA 2017 to present Responsible for re-architecting and transforming a monolithic application with over seven-million lines of code into a micro-services system. Separated existing large domain into sub domains (bounded contexts) using the DDD approach to implement a set of independent yet collaborative micro services. Distributed long running processes across multiple machines, collaborating in a cluster environment; which reduced the original execution time by 600% with zero downtime and message delivery guaranteed. Additionally, this approach allowed blue/green deployments and reduced the cost by 40%.

Unique Solutions: Developed distributed system using the actor programming model and fully leveraged asynchronous message passing semantic. This system embraced the Reactive Manifesto ensuring the system remained fault-tolerant, message driven and capable of self-healing in the case of errors.

Current Demand: Re-build validation engine that processes over 170,000 employees. The new implementation of this validation engine, using the Actor-Model, reduced the execution time from 5 hours to under 20 minutes.

Technologies Leveraged: ASP.NET MVC, Web-API/REST API, C# 6.0 and .NET Framework 4.6.1, Entity Framework OR/M, F#, SQL, Akka.Net, RabbitMQ, MongoDB Sr. BACK-END ARCHITECT, StatMuse, San Francisco, CA 2015 to 2017 Responsible for constructing and implementing Natural Language Interfaces (NLP) for sports analytics. Introduced machine learning technology to enable Natural Language Generation (NLG) in order to understand arbitrary queries and provide meaningful responses.

Unique Solutions: Developed query expression infrastructure to eliminate dependencies from Entity-Framework and allow different data source plug ins. Tokenized human input queries and converted them into an Abstract Syntax Tree (AST) representation, transformed into SQL statements - reduced original code by 70%

Customized Results: Implemented custom Type-Provider for Stanford TokenRegex to obtain static type checking at compile time for regex strings, dramatically improving development productivity.

Current Demand: Built Alexa skills and web api to integrate main application in a mobile implementation in order to generate sports analytics.

Technologies Leveraged: Web-API, C# 6.0, Entity Framework OR/M, F#, SQL, Stanford NLP Sr. SOFTWARE ARCHITECT, Microsoft, Reston, VA 2012 to 2015 Responsible for designing the overall structure of new software systems. Conducts design reviews, code reviews and progress reviews. Participates in the development of Information Technology Strategies and Roadmaps in support of the business strategies.

Expert Analysis: Developed high performance search engine leveraging NoSql technologies to integrate in a SaaS CRM solution. Designed Rest (like) API to expose functionality for portable devices.

Globalization: Designed and developed multilingual and localization support for “poli-portal” architecture.

Technologies Leveraged: ASP.NET MVC4 & 5, C# 6.0, Entity Framework OR/M, WCF, Javascript, SQL, HTML5/ CSS3, Bootstrap, Knockout, JQuery/AJAX

SOFTWARE ARCHITECT, Unisys, Consultant Company, Alexandria, Va 2011 to 2012 Builds web based near real time Home Land Security intelligence solutions that continuously monitor data for anomalous behavior.

Real Time Analysis: Developed simultaneous loading process for multi-faceted data retrieval system to create a synchronized structure while enabling secure collaboration.

Expert Analysis: Created a windows based application using WPF/C# to import and analyze several GB of insurance data and statistics integrated into a custom web site which rendered the data using static HTML. Immersed in full-spectrum software design of application using DDD methodology. Improved data analysis by 300%.

Technologies Leveraged: WPF/C# 4.0, MVC4, Async, Entity Framework 5, WCF, HTML5/ CSS3, Javascript, JQuery, AJAX, Bootstrap, KnockoutJS, AJAX, SQL

RICCARDO TERRELL PAGE THREE

SOFTWARE DEVELOPER, Edgar-Online, Financial Company, Rockville, MD 2010 to 2012 Responsible for creating client tools and leveraging the latest technology to refine features of XBRL (eXtensible Business Reporting Language), the financial standard mandated worldwide to improve the transparency and efficiency of business reporting.

Agile Analysis: Customized html & XML parser with built in constraints to convert web pages and financial data to XBRL and simultaneously check for accuracy within set standards. Improved performance and ease of use for the commercial market.

Accelerated Performance: Re-build and re-architect $5M/41 Library application to run multiple tasks concurrently and leverage multicore machines. Streamlined analysis of more than 25Gb of data to reduce the number of roundtrips per database requests using the C#, Iron-Python, Ado.net, Wcf and Wpf technologies. SOFTWARE DEVELOPER / PROJECT MANAGER, Private Company, Montgomery Village, MD 2009 to 2010 Managed Asp.net / C# development projects in Multi-tier applications. Customized data-driven controls leveraging Web Services and WCF technology. Created internal framework to improve processes in developing Web applications.
