What I worked on

⚙️Government contracting pipeline

I was the sole programmer on an 18-step Python, PostgreSQL and Airtable pipeline on Heroku that turns raw government contracting data into ready-to-use leads for Nerevu's internal team.

⏱️Lead prep time

Minutes to prepare one lead.

🧪CI & testing: fixes that stay fixed

I set up the project's error logging and its first CI, which grew to about 1,000 tests. Every production error followed the same loop, so a problem couldn't quietly come back.

1 · Error loggedProduction error is captured automatically

2 · IssueIt becomes a tracked issue
→
3 · TestA test that recreates it is written first
→
4 · FixThe fix ships with that test pinned in CI

🏦Financial data integration

Kept a mortgage lending client's production SQL Server and SSIS integration running every night.

  • Stored procedures for the nightly loads
  • Dynamic table-comparison scripts across 268-column loan tables, reconciling each load against source
  • SQL Server Agent job monitoring with SQL and SMS alerts when a load failed

🔻Hiring funnel analysis

Analyzed Nerevu's internal 1,000+ applicant hiring funnel stage by stage, and modeled which candidates advance to the next stage.

📊ATS & CRM dashboards

Customized Nerevu's internal applicant tracking system (ATS) and CRM dashboards.

🔍Classifier & LLM evaluation

  • Research on people: designed the accuracy tests that decided whether a name-based demographic classifier was fit to report on in a market disparity study. It replaced a 30-minute manual review per record.
  • LLM quality: wrote an automated scorer that grades LLM output inside the production pipeline, before anything downstream uses it.

📝Reports & infographics

Produced the infographics and charts, and edited the final documents, for two government reports:

  • Municipal data governance study
  • Market disparity study, with colorblind-safe visuals and an executive recommendations table
