The spring of 2024, I took a semester off at Olin to take a position as full-time Co-op at H2Ok.

H2Ok is an IOT company pioneering AI-driven optimization of precision automation to reduce manufacturing waste and time. H2Ok is part of the largest climate-tech incubator, Greentown Labs.

Working at a small company, I was able to utilize my interdisciplinary skillsets to design and manufacture parts, develop a faster testing rig and software , and redevelop the UX and UI of customer facing web platforms and products.

Sample Testing Redesign

My main project was to reduce the time needed to sample test, the first step of customer onboarding. Testings consists of mixing different concentrations of customer samples to train the ML model.

Here is the original sample test rig. Before my redesign, only the CTO was able to navigate the two day long process due to it's complexity and confusion.

Pain Points include:

  • Time

  • Only attached to outdated sensors

  • Difficult to clean because of corners and shape

  • Annoying Screws

  • Code with a steep learning curve

  • Unorganized and hard to use CSV setup

Here is the new sample testing rig that I designed and manufactured.

Features include:

  • Magnetic sensor mounts and lid

  • Smooth interior with no corners

  • Fits new sensors and sensors with can

  • Ability to put sensors at 180 deg or 90 deg

I created a new software platform that was intuitive and faster.

Features include:

  • Guided walkthrough on labeling the CSV and setting the settings

  • Guided walkthrough on the sample testings within the code

  • Ability to change settings easily at any point

  • Ability to automatically cycle through different settings
