As the 5th full-time engineer at this rapidly growing start-up in health care automation, I took our product from infancy to scale. My work has spanned the full stack but increasingly focused on the back end. Technologies used:Node, TypeScript, PostgreSQL, Docker, Kubernetes, GitHub, React, Python, C#, C++, Puppeteer, RPA

As the sole full-time software engineer for this IoT medical-device startup for most of its life (joining as the 4th employee), I developed a full software stack—including firmware, Android apps, web server, web front-end, and database—which is now running successfully in production. My work has also included:• Applied several machine-learning approaches to real-time detection of human body positions on pressure maps. • Created an algorithm for crosstalk cancellation on our sensor array (now part of its patent).• Extracted analytics data spanning all aspects of system operation and applied statistical analysis extensively for interpretation and recommendations. Technologies used:Java, C++, SQL, JavaScript, Android, Spring, PostgreSQL, MySQL, SQLite, OpenGL, Arduino, BLE, Heroku, Google App Engine, REST, Dojo, jQuery, Thymeleaf, MyBatis, Liquibase, JUnit, Selenium, Maven, Gradle, Jenkins.

Taught general chemistry to multiple sections of students, leading discussion sections and labs, assisting in writing exams, and grading homework and exams. Consistently commended by students and faculty for outstanding effectiveness in communication and instruction.

Lead software developer at a start-up specializing in imaging and records management, primarily targeting the health care industry.• Took over the company’s second-largest application immediately after hire, to automate OCR verification for payment posting via EDI in a sophisticated UI with a multi-threaded engine interfacing with multiple legacy database systems.• Authored the MSI-based installer for the company’s flagship product using WiX, including WiX extensions in C++. Also contributed to the open-source development of WiX itself.• Worked directly with customers to develop custom OCR extraction components and custom web applications.• Persuaded the team to move the main product from a client/server to a three-tier model, and led the team in implementing a new middle tier. Later participated in replacing this with .NET web services in C# using a SQL Server back end, rewriting the entire data layer in T-SQL.• Co-authored the web interface to the company’s main application, developing all the code for doing client-side viewing, redaction, annotation, and printing of images, pushing the limits of dynamic HTML to deliver a browser-based document imaging system.• Developed multithreaded Windows services for automated importing.• Was the go-to guy for solving hopeless and mysterious problems.• Substantially revised & continually maintained the team’s automated batch build process.• Authored documentation for most of the company’s products.• Introduced NUnit unit testing to the team’s development process and coded the first unit tests targeting it. Also assisted in quality assurance through manual tests and authoring test plans.• Mentored other team members in COM+, MSI, and other technologies.Technologies used:Visual Studio, C++, MFC, ATL, Win32, COM+, C#, .NET, XML, XSLT, SQL Server, ADO.NET, web services, SOA, DHTML, JavaScript, Java, JSP, ASP, VBScript, ASP.NET, MSMQ, EDI, MSI, WiX, SilkRadar, NUnit, Virtual PC, SourceSafe
