What I do

Test strategy and release sign-off

Deciding what needs testing, how deep to go, and whether a release is ready, based on how people actually use the software.

Functional and data testing

Functional, usability and regression testing, plus checking the data underneath. Most of my current work is LIMS testing in Power Apps and Dataverse.

A QA process developers follow

Structured test suites, bug reports developers can reproduce, a clear handoff for when work is ready to test, and tracking so nothing gets lost.

Quality in regulated labs

SOPs, audits, ISO 17025 and data integrity. I worked under these rules as a chemist, so I know what regulated labs need from their software and test for it.

Experience

Laboratory Informatics Scientist (QA Lead)

SynapticSci, Remote, March 2025 to present

I lead QA for SynapticSci's three Power Apps-based LIMS platforms, which serve general, veterinary and transportation materials testing labs. I write the test cases, run the testing, and groom testing tasks and bugs.

310+

manual test cases written, organized into 70 suites

developers working in the QA workflow I set up

• Own test strategy and the final QA sign-off across three products.
• Set up the company-wide QA workflow 15 developers now use: how work is flagged as ready to test, how bugs are logged and groomed, and how results come back.
• Built a QA dashboard in Azure DevOps that pulls testing tasks and bugs from three projects into one view, flagging unassigned, high-priority and 14-day-old work so nothing goes stale.
• Led testing for five brand-new features end to end, from first build through release.
• Wrote 310+ manual test cases across 70 suites covering core workflows, new features, regression and edge cases, plus 20 reusable shared-step libraries and the QA documentation and standards behind them.
• Writing automated regression tests with Playwright and Postman, with help from Claude. They run locally against our test environments for now; the goal is to run them on every code update.

Senior Analytical Chemist

Encore Labs, Pasadena, CA, July 2018 to February 2024

• Helped bring in the QBench LIMS to automate upload and approval of results: explained to the developers what the lab needed, then did user testing once it was in. Data errors fell from 15% to under 5%.
• Led data review for over 10,000 data points a day, supporting 270 clients and $600K in monthly revenue.
• Trained analysts and supervisors on instruments and data review; department productivity rose 14%.

Analytical Chemist

The J.M. Smucker Company, Burbank, CA, June 2015 to July 2018

• Audited 75 standard operating procedures for compliance and helped the lab earn ISO 17025 accreditation.
• Analyzed ingredient data across 100 product lines, about 20 samples a day.
• Performed cost analysis that saved $140,000 a year through better purchasing.

Skills

Earlier work

Projects from my 2024 data science training and my volunteer work, where I learned to collect, clean and check data.

• Weightlifting results scraper

  Scraped international weightlifting results with BeautifulSoup, flagged failed lifts, and fuzzy-matched athletes against another dataset.

• Knitting pattern recommender

  Pulled 15,000 patterns from the Ravelry API and built a Streamlit app that suggests similar patterns.

• Hack for LA, volunteer, 2024 to 2025

  Reviewed and catalogued datasets from the LA City Controller's site to pick out ones worth future projects.
