Manager and lead Software Engineer of a team of other Software Engineers. Responsible for developing production test automation software and statistical data analysis.• Solely developed test automation and calibration software for the AC Battery, Revenue-Grade Metering (RGM) gateway, and 5th-generation microinverter using Python2 on the Eclipse IDE with PyDev.• Used multithreading for the automation and calibration of the test automation for the gateway product, so many units could be tested and calibrated in parallel.• Uncovered problems early in the product development phase by developing regression, smoke and unittests that are run nightly via Continuous Integration.• All software developed is highly reliable and achieved automotive-grade First- Pass Yields (FPY) of 98.5% FPY or higher for high production volumes of 10,000 units/day or more.• Saved millions of dollars in capital equipment by reducing test automation times.• Constantly strove for efficiency by developing many key tools using numpy, PANDAS and Django to reduce busy-work and aid with statistical data analysis.• Frequently used TDD, BDD, unittests, peer programming and code reviews.• Strong cross-functional collaboration skills: developed firmware and software release process to mitigate field risks.

Responsible for developing test automation software. Built in-house a production test automation framework from scratch with database support and grew our automation volume capabilities from nothing to 4M+/yr.• Defined, architected and implemented the software automation of the entire end-to-end production test processes using Python2 on the Eclipse IDE with PyDev. The automation software is run on 100% of all units that ship from the factory.• Developed calibration software for the first 4 generations of microinverters.• Developed APIs using MySQLdb and requests to save test results to a MySQL database. Created many innovative tools to control the test process flow via software. For example, developed software to ensure 100% of products tested must pass before going to the next process step.• Using PyInstaller, mercurial and Dell eKace, created tools to bundle the test software into a self-extracting installer that can be deployed to hundreds of client machines within minutes.• Wore Data Scientist hat on numerous occasions: uncovered numerous key quality issues using statistical data modeling of large sets of data via PANDAS and numpy.• Collaborated to create a common set of Object-Oriented test equipment drivers, which are used company-wide.
