Owned and led targeted, revenue-critical systems projects, specializing in data engineering and team leadership. Systems architect, technical product owner, team lead, project lead, coder, mentor, UX designer. Discovered and attacked four core initiatives—with breakthrough results in each.The details: http://tjames.com/projects.htmlA highlight: I started, led, and ultimately managed the data science and analytics team at change.org, driving both systems architecture and team culture. We brought predictive analytics using machine learning to our primary driver of traffic and revenue: email. Result: immediate 30% conversion rate improvement over manual targeting and radically refocused media staff of dozens around the world. Then I initiated and drove bringing broad business analytics to Amazon Redshift with heavy ETL from online MySQL DB. Get the whole story: from Amazon re:Invent 2013: https://youtu.be/YQ9Y7HlxGmU?t=3m35sExtensively employed: AWS cloud services (EC2, S3, Redshift, EMR, RDS, ELB, AutoScaling, cross-AZ deploy); javascript/node.js/angular.js/D3.js; postgres; redis; TDD (unit, integration, angular UX); Hadoop/Cascading/EMR.

Great engineering is not enough. Valuable software demands a strategy to discover and deliver to real customer/market needs, and a risk-driven approach to project management. I helped RF better navigate the waters of software making as a professional service.

We created Voxer, the iPhone walkie-talkie voice/text/photo messaging app, with backend server.• Collaborated to build Python/CouchDB/Linux server, bringing closure-based programming for tighter code done faster, later owning major subsystems in (Crockford-style) JavaScript/node.js-based rewrite. Our design divided latency-sensitive processing from throughput-sensitive.• Built cross-platform mobile-client core in C++, with select()-based frame/control loop to handle n audio streams at 50fps, simplified HTTP layer, and write-through audio cache handling recorded/live transitions, using STL and Boost, with unit tests.• Built entire first incarnation of our iPhone UI, complete with sexy-yet-tasteful animations/transitions.• Initiated and drove engineering-wide conversion from SVN to git, mentoring colleagues to grok the git model, bringing the team to rapidly get maximum productivity with minimum pain, and to their own sense of confident competence.• Mentored in Python and C++; gave engineering-wide “teach-ins” on essential topics like memory handling mechanisms and best practices in C++ and Objective-C for iPhone.• Integrated Facebook (for authentication and friends), client and server side, helping us go viral.• Optimized our CouchDB “no-SQL” database using automated speed tests to mimic real load characteristics for 6-10x query throughput improvement; created zero-downtime single-server schema migration tool.

• Refactored and reengineered the SBRS DNS system, IronPort’s first line of defense against spam and viruses, into a cohesive, maintainable, fast, tested and correct implementation, in Python and C++, utilizing comprehensive unit tests, static call visualization, and organized logging.• Built web dashboard application for real time monitoring and control of distributed server processes, in Python.• Collaborated with team to effect complete and on-time project deliveries, balancing development resources, milestone dates, business and technical feature valuation (scope), and keep/rewrite.• Created static call graph visualization tool for Python, vital for rapid analysis and refactoring of complex, crufty, extant code bases, using GraphViz. • Python, MySQL, C++, SMTP, DNS, BSD.
