Hands-on development role where I provided business value while deepening my knowledge of AWS and enhancing the organizational architecture goals. I sought out this role after spending time in technology leadership because I love to write code. In this position, I actively supported, participated in, and promoted the existing culture of TDD and Pair Programming. I developed and deployed various technologies to production, including React, Typescript, Scala, NodeJS, RDS Postgres, DynamoDB, AWS CDK (infrastructure as code), AWS Lambda, AWS API Gateway, AWS SQS, AWS Route53, AWS WAF, Docker containers, and deployment into AWS ECS, Linux.

Hired via acquisition from previous position. Scope increased to architecture for a business unit that was ultimately sold for $1.7Bn. Responsibilities increased to presenting technical solutions to senior leadership including technical architecture, financial implications, high level project breakdowns and scheduling, and staffing level recommendations.Initially responsible for architecture of 1M+ LOC across many new and existing services. Architecture based on loosely coupled, independently deployable services communicating via REST and coordinated with message passing.Beyond growth in technology leadership, I gained specific growth around security. Pen Tests, Security Architectural reviews, network security, improving security posture of existing services and moving security focus to the fundamental design phase for new services.Technologies include C#, .Net Framework, .Net Core, ASP.Net, SQL Server 2016, AWS, Azure, Azure Service Bus

Responsible for software architecture and direction for a SaaS company that crunched billions of records for a large proportion of the hospitals across the US. Total database footprint ~1 petabyteArchitecture based on loosely coupled, independently deployable service coordinated with message passing.Company was acquired by TransUnion for ~$100MM. I was directly involved in the acquisition.Technologies include C#, .Net Framework, .Net Core, ASP.Net, SQL Server 2016, Azure Service Bus

Responsible for all technical and cloud architecture. Scaled to serving about 1.2M images per minute while reducing cloud bill from $40,000/month to $5,000/month. Integrated multiple disparate APIs, including Shopify, BigCommerce and Amazon, handling millions of price and other product changes daily. Gave users the ability to manage their products and track analytics about them in one place. System was polyglot and cloud-based using Azure. The scalable handlers rendered exactly the data the Node-based website needed to serve. Images were hosted in Blob storage and cached on a server built for the task of serving images of various resolutions quickly.Main components:- .Net WebAPI Web Role, backed by NServiceBus and processing Worker Roles which rendered exactly what needed to be served to MongoDB- MEAN-stack (MongoDB+Express+AngularJS+NodeJS) client-facing applications that use this API- Python JSON-LD processor- PHP analytics proxy- Flash widget for deep Facebook integrationWe employed continuous integration (Team City) and deployment (Octopus Deploy) between our GitHub servers and the cloud endpoints (Mix of Web Sites and Web/Worker Roles in Azure). We deployed multiple times per day by accepting pull requests.We built everything using automated tests. Tools (in no particular order) include:- Strict CQRS (command query responsibility segregation)- Azure Web Roles, Azure Worker Roles, Azure Websites, WebJobs, CDN, Service Bus, AutoScaling, Cache- ASP.NET MVC, ASP.NET Web API- NodeJS, Yeoman, Jasmine, Angular, Express, Jade, Compass - C#, F#, SpecFlow, MSTest, NServiceBus, JSON-LD, MongoDB, CouchBase

Developed distributed processing system for healthcare data. Leveraged message passing via Azure Service Bus to offload work from SQL Server's CPUs to commodity CPUs, enhancing performance and reducing cost. System was built in .Net with C#, IoC via Ninject, Microsoft Azure Service Bus, Entity Framework 5, Visual Studio and SQL Server 2012

Systems level C++ development on Windows 8, Windows 7, Windows Vista and Windows XP. focusing on Windows Services, inter-process communication (named pipes, mailslots), boost (asio, interprocess), Google protobuf, multithreading, WPP tracing, unit testing via Boost and CPPUnitDistributed systems engineer creating tools to report on distributed systems' activity using tools like ActiveMQ, RabbitMQ, jetty, Riemann.ioWeb development using Java, Clojure, Groovy (Grails)Created distributed system monitoring tools for other developers using .Net 4.5, Task Parallel Library (TPL), Resharper, Visual Studio, moreOther technologies frequently used include: MongoDB, SQLite

Received grant from the National Endowment for the Humanities to process citations from all sources into a human-collaborative wiki format. After the grant, the work went on to be used in production at the Stanford Libraries.Technologies include Visual Studio, Microsoft Azure, SQL Server 2008, F#, C#, MySQL, Fluent NHibernate ORM, NUnit, Subversion.

Now-closed music sharing platform. I introduced RabbitMQ and message passing to scale the transcoding system which needed to convert most of the music owned by US publishers from uncompressed into various compressed formats. Other impacts include work with the Facebook API to allow streaming previews of music and purchasing directly from a user's feed. Technology details include AWS, for compute and storage, .Net services, message-passing via RabbitMQ, Mono, NUnit, Resharper, Visual Studio, Castle Windsor IoC container, Flash Builder, Flash Pro, NHibernate, memcached, Razor View Engine, Amazon Simple Pay, Amazon Queues and Notification systems (SQS, SNS) and more.

Greatest impact was to developments on the core engine. Details withheld for reasons of confidentiality. Additionally, won an innovation award for work that led to the linked Wired article.Responsibilities have ranged from developer to team lead on a number of applications for the intelligence community on a variety of platforms using .Net 3.5.Additionally, practiced test-driven development, created design documents, performed interviews (something I truly enjoy), code reviews, and depending on my assignment, created projects from scratch, enhanced current code and created plans to reduce defects in existing products. I have also navigated the strict and exhaustive requirements to bring new technologies to the company, and generally worked from day one to increase the value Overwatch can bring to its diverse customer base.Technologies include .Net 3.5, C#, WPF, ASP.NET, WCF, SQL Server, Fluent NHibernate, NUnit among many, many others.

Airlines needed profitability numbers quickly after 9/11, but their reports required 30 days to crunch through the billions of records. We got the report generation time down to 4 hours on existing hardware. Billions of records by lunch on 2002 hardware.High-level idea was to offload a substantial amount of the processing from the Oracle machines to an underutilized pre-existing mainframe. Solution used C++, message passing and POSIX threading. When the mainframe was retired, we moved the offloaded work to Windows-based servers no more powerful than an enthusiast would have in their home. The development time for that migration was minimal and performance increased..Following that, I solved several more business problems for the airline, including implementing the TSA-mandated security policies using Oracle, consolidated time-tracking systems for the organization and implemented a substantial vendor management system using C#/ASP.Net
