DB - NoSQL

I've worked for years with MongoDB, Couchbase, ElasticSearch, and Reddis. Currently, I am working on numerous microservices that rely on Couchbase caching. In my previous company, we built a SASS that was based in large part on MongoDB for our persistence layer. We also leverage ElasticSearch for text-based searches and better nested document searches.

Hands on Team Leader

CrediFi

Led a team of 6 developers tasked with building the server-side and client-side for all of our core products, as well as all associated micro-applications and APIs. This I did while programming at least 50% of the time, and adhering to the tenants of Domain Driven Design, Test-Driven Development, and Agile development.
Hands-on coding achievements:
• Modeled and coded (in C#) a significant portion of the core libraries used to ingest data on millions of loans, properties, and companies daily
• Implemented a hybrid persistence layer by integrating ElasticSearch, S3, and MongoDb
• Architected the back-office CMS and client-facing UI, and built a large percentage of both
• Spearheaded the conversion of our Flagship site from Angular 1 to Angular 2+ (and from Grunt to Gulp)
• Created a tracing mechanism to measure system complexity and monitor race-conditions
• Built a large percentage of the APIs used by our developers using WebAPI
• Managed the development schedule for the team for each iteration conducting dev plannings with Product, assigning tasks and bugs, and adjusting as needed
• Server-side built in C#; Persistence is a hybrid of S3, MongoDb, ElasticSearch, and MySql; Eventual consistency handled through RabbitMq; Inversion of Control handled by Unity; Deployment on AWS

January 2011 - February 2014

Senior Software Developer (Full Stack)

Kenes International

• Responsible for the design and development of web-based projects, mobile apps, and internal
applications requested by Kenes and its clients. Most applications were written using MVC 4, with a heavy emphasis on AngularJS, while some legacy applications were a combination of ASP.NET Web Forms, Web Services (WCF), and significant client-side scripting (JQuery and Knockout). Many projects involved the integration of 3rd-party APIs (Facebook, Google, Yahoo, etc.).
• Knowledge and use of various design patterns (MVC, MVVM, Web Forms) was integral, as
well as the use of ORMs (Entity Framework and NHibernate). All server-side coding was
done in C#.
• Projects included: Custom-made cross-platform BI applications, Facebook-integrated friend referral systems, online registration systems and survey evaluation forms for medical conferences throughout the world, custom-built Content Management Systems for various medical societies, mobile apps for WM 6.5 phones, and stand-alone Web apps aimed at significantly streamlining the Kenes work process.
• Responsible for designing and creating the database schema for each new project, and
implementing them using an SQL Server 2012 or 2008R2.
• Responsible for converting legacy systems built in asp classic, using Access databases to
websites that are built in ASP.NET 3.5/4.0, using an SQL Server 2008.
