Greg Vincent


Senior technologist with twenty years of Internet industry experience. I built my first commercial website in 1994, joined my first startup ( in 2000, and have since built multiple highly successful consumer websites for companies like YouCaring, Sony (Playstation), OpenTable, and I love building applications that have big impact.

As an engineering manager, I leverage my over twenty years of software engineering experience to keep my team happy, healthy, and continually challenged. As a software engineer, I'm a full-stack generalist, able to supplement my team however and wherever needed. I'm equally comfortable in the database, or writing an SMTP mailer or REST API, as I am in JavaScript or CSS.

As an architect, I'm obsessively determined to squeeze out every last bit of system performance that I can. YouCaring was one of the worst performing sites in crowdfunding when I first started there in November 2014. By end of April 2015, our start render had surpassed the industry performance leader.

Specialties: JavaScript, Backbone.js, React.js, Redux, Single Page Applications, jQuery, Gulp.js, C#, REST APIs, Webcrawlers, HTML5, CSS, Agile, Software Internationalization, Website Performance Optimization, Search Engine Optimization (SEO), Git, ASP.NET, HTTP, SQL, SMTP, OOD/OOP, APM

Vice President of Engineering


Responsible for all aspects of systems development and engineering for, from setting strategy and roadmaps which evolve the platform, to driving the processes, design, implementation and production support for all YouCaring applications and infrastructure, both internal and customer facing.

Notable accomplishments include:

• Reduced start render time from an average 9.5 seconds, to an industry leading average of 2.2 seconds. Established and enforced a strict performance budget to keep YouCaring from losing its newfound performance edge.

• Conceptualized, designed, and implemented systems which brought much greater reliability to critical YouCaring application functions like payments, email delivery, error and transaction logging, and much more.

• Architected and built a suite of REST APIs that now power YouCaring's image upload, manipulation and management capabilities.

• Handled day to day datacenter operations for, and built out an extensive system for application performance monitoring and alerting for the production site.

• Developed all of the SDLC-related processes which guide software development at YouCaring. Everything from software builds and deployment, to code review, source code control, and code instrumentation for application performance monitoring.

• Identified an opportunity for, and subsequently developed and negotiated a partnership with Smyte, a company which now provides fraud detection services for YouCaring.

• Secured YouCaring infrastructure after it came under distributed denial of service attack, and built a new, better performing, more resilient, and highly secure infrastructure as a result. We have not seen a single DDoS recurrence ever since.

• Represented YouCaring as a speaker at New Relic's annual FutureStack conference in November 2015.

Responsible for the day to day operation, and ongoing development, of

Recruited, hired, and managed a team of eight engineers. Inherited an underperforming/outdated ASP.NET webforms-based application. Lead the technical effort to implement a brand new website design, with a focus on web performance optimization, SDLC process improvement, elimination of proprietary interfaces, and better error reporting/instrumentation.

Instrumented primary application flows using a combination of Sentry/RavenSharp, Rollbar, and New Relic custom transactions, to help understand what the existing performance and reliability issues were. Implemented Akamai CDN for edge caching, began migration of user submitted static content from Rackspace Cloudfiles to Akamai.

Began exposing much of the legacy backend via REST API. Managed the design and development of multiple backend partner integrations. Migrated from an insecure public cloud-based infrastructure to a private, firewalled, co-located infrastructure, including vendor selection and contract negotiations with multiple vendors.

These efforts resulted in a reduction in average perceived page load time by a factor of 300-400% on

Senior Software Engineer


Designed, prototyped and implemented a large scale, automated data acquisition system (a webcrawler) for collection of commercial real estate information via the Internet. The system design was fully multithreaded, targeting the web sites of over 6,000 major US retailers - up to 40 simultaneously. The process identified, parsed, and extracted relevant data from the target web site, saving it to a database for analysis and geo-coding. To date it has identified more than 1,000,000 commercial real estate properties nationwide. The data collected was instrumental in the successful launching of CoStar’s new retail product. (see for more information) The HTTP client implementation was created from scratch using framework classes for TCP session management only. Technologies used included C#, TCP/IP, ASP.NET, WinForms, SQL Server, Regular Expressions and Microsoft Application Blocks for data access.

Developed a Windows Presentation Foundation (WPF) based application for real-time reporting on new property and tenancy data added to CoStar’s data warehouse. The solution involved heavy use of WPF with manipulation of three dimensional models, MSMQ, and SQL Server 2005 with stored procedures.

Software Engineer


LifeMinders.Com was the Internet's first, and largest direct email marketing company. My responsibilities included developing and maintaining LifeMinders email generation software, delivering highly targeted and customized email content to each of LifeMinders 22 million subscribers. The software would match users with appropriate content based on a personalized profile of the user, then generate a unique email message for each user based on their interests. Also, by implementing the ESMTP pipelining specification I increased email delivery throughput from around 2 Million to over 8 Million individually customized email messages per hour.

I also created LifeMinders' bounced email management system. The system utilized MSMQ and VB for asynchronous processing of SMTP delivery failure notifications against our customer database. The system would then deactivate customers whose email accounts had been closed.  

Developed a new application for real-time validation of member email addresses using C#, TCP, DNS and SMTP. This required creating a fully resolving DNS client from scratch (pre .Net 1.0 DNS client did not support lookup of MX records). The application sent/received UDP Datagrams to resolve DNS queries and used TCP/SMTP to validate email addresses against the targeted domain's mail exchange server.

Worked with product designers to turn their design concepts into an HTML template for all of LifeMinders' products.

Most applications developed with Visual Basic 6, MS SQL Server 2000 and ADO - some using XML, MSMQ and MTS.
