Started and led team to rebuild Sendwave and WorldRemit's legacy pay-in services as a combined Java Springboot-based gRPC service on AWS. New service saved the company on interchange fees, reduced operational costs to the company, and improved treasury team's working capital flexibility by enabling the organization to do hourly settlement. New service was code complete in five months and currently processes $500MM/month.

Scaled the team and processes from 0 to 20+ members. Managed three sub-teams and three individual backend contributors, occasionally contributing my own backend code changes to the Python codebase.- Oversaw release of dozens of backend and mobile features.- Mentored new line managers for respective mobile platforms. - Hired Test Engineering Manager and worked with the new test engineering team to establish test and release processes.- Lead re-architecture of backend from monolitic server to a codebase supporting multiple services, making the application much more scalable.- Established new standards and best-practices for APIs and fostered re-writing most of our API to conform with RESTful standards and documentation.

Created and led mobile development teams "from scratch" to redesign and refactor Sendwave's flagship mobile apps (Android and iOS). Involved in hiring, mentorship, and planning for development and deployment of new application and lead team through feature improvements. - Implemented agile software development and CI/CD processes across mobile teams. - Improved mobile application codebase by migrating to MVVM and VIPER architectures, and gradual rewrite from Java/Objective C to Kotlin/Swift.

Built new features for Python (Flask) based backend and Android client applications, as well as some light iOS development work. Some of the fun stuff that I got to do:- Integrated with third-party mobile wallet and bank aggregators based in Africa- Integrated with a new payment processor, resulting in savings to the company of ~$1m/year- Added biometeric login to the mobile apps- Added functionality to support for expanding into four new countries- Localized app, adding support for five additional languages, currency, and date formats

Implemented new features on Rails-based back end and React/Redux ES6 based front end. In addition to React and Redux, the front end made heavy use of CSS modules, webpack, and jest-based unit tests. Primary areas of focus were user onboarding, payment processing, and adding multi-media features (e.g., video and multi-image posts via Twitter and Facebook's API).

Decided it was time to work on my front-end chops to ensure I could still claim to be a "full stack" web developer. Augmented staff of Time Warner Cable through contracting agency Sigient (now defunct)- Rebuilt portions of front-end of customer portal for major U.S. cable company. Changed out Backbone-based components in favor React. Updated build process to use Webpack and Babel to support ES6 and JSX.- Worked with external auditing agency to update customer portal to be fully accessible to disabled users.- Added features to existing Backbone customer portal and Grails-based backend.- Added Jasmine based test suite to validate existing front-end business logic.

- Reigned in development process once we got to a team of about six. Introduced Scrum to the group, started standups, IPMs, retrospectives, "planning poker," all the other Scrum ritual goodness.- Contributed to creation of the hiring process and helped CTO with staffing the engineering team.- Made technical presentations to potential company investors.

Fourth hire at a Cambridge-based startup building an online marketplace matching auto repair shops with vehicle owners needing service.Some of the more interesting features that I worked on included:- Elixir/Phoenix based microservice: Extracted vehicle database functionality from main monolithic Rails app into an Elixir based microservice using the Phoenix web framework.- Implemented a PubSub system using a Faye server to synchronize call center screens. Later used the PubSub system to demonstrate an OBDII integration prototype.- Geographically-based email algorithm: Based on the location of a service request, gradually expand the radius of shops notified until a maximum number of responses were attained. Used PostGIS to identify candidate shops.- Automated workflow: System that dynamically observed the state of domain objects in the system and kicked off "events" (notifications, other state transitions, etc) based on domain state. Totally configurable from an admin portal, allowing member services to tune communication with users without development resources.- Implemented an automated system for generating estimates based on vehicle owner's requests.- Wired up an IVR using Twilio to allow repair shops to settle their deals by phone.- Created an appointment "negotiation" system for use between vehicle owners and service providers.- Tasked with improving SEO for the site and got a 5x increase in inbound organic traffic with provider listing and maintenance schedule pages.- A bunch of other stuff I'm probably forgetting. It was a startup, almost everything had to be built from scratch! :)

As CTO I led the software development team. Determined strategic focus for new technology and methodologies. Worked with sales team to onboard and form relationships with new clients. Led internal projects and initiatives to expand Burnside Digital's offerings from solely service-based to product-based.

Lead the CityEats team, comprised of 6-10 developers spanning Ruby on Rails, Android, iOS, and AWS DevOps engineers. Made monthly planning visits to the customer site in NYC.

Developed Android and Ruby on Rails-based web applications, most notable contributions were to the CityEats and MaaSive projects. CityEats was a realtime restaurant reservation system created by Scripps Networks (think "OpenTable, but prettier and for higher-end restaurants with celebrity chefs"). MaaSive was a mobile-as-a-service product similar to Parse.

Ceres Logic is my one person "company," where I worked as an independent consultant for several clients spanning several industries, including:- Sony Music, for whom I helped develop Ariama, a Rails-based online music browsing and purchasing platform for classical music.- Intridea, where I developed Digital Trend's Android application and worked on their internal entprise chat Android application.- BlueTarp Financial, where I developed a credit application management system using Java's Tapestry framework.

Developed web services that allowed API users to search and query music catalog metadata. Created proxy servers to enhance the advertising capabilities of the online music service. The following technologies were used to implement these services: Spring (IoC container and MVC), EJB3 (Remoting and JPA), Hibernate, Lucene, FreeMarker, and JBoss.Components would have been part of an amazing cloud-based music streaming and playlist service, if only the company hadn't lost its funding.

Enterprise Java and SQL Developer. Developed internal credit application and scoring interface and collaborated on public-facing account maintenance web interface. Technologies used: JEE, Tapestry, Hibernate, Stripes, SQL Server, Postgres.

Architected a major re-design of current billing and customer care product, creating J2EE web services API for an existing legacy subscriber management system used in the Wireless Telecommunications industry. Designed and developed a SOAP-based service integration point for Amp'd Mobile, a nationwide MVNO, that managed customer accounts, content delivery, billing, and payment. Created and collaborated on industry-leading voice and data rating engines for postpaid and prepaid billing system used by tier-3 and tier-2 regional mobile carriers.Technologies used: J2EE, Hibernate, Spring, Struts, C++, SQL, Sybase, Cognos Axiant/PowerHouse, Mobile OSS/BSS.

Co-Developed embedded servo-control system for the Atlas line of server grade SCSI disk drives.

Developed automated test suite for Digital's Multia and Printer Driver products.
