Drew Kozmary, PhD

Senior Software Engineer · data visualization, design systems, and AI agents

I build the parts of a product people actually look at: charts, design systems, and the UI that explains complex data. I have 7+ years shipping TypeScript/React at Honeycomb, Webflow, Rover, and T-Mobile, and before that a PhD in accessible human-computer interaction. These days I also build AI agent workflows that make engineering teams faster.

Experience

Honeycomb

Senior Software Engineer

Dec 2025 – present

Built Honeycomb’s next-generation charting foundation on AG Charts. Another engineer used it to ship a brand-new chart type in under 24 hours.
Was on a cross-team tiger team that shipped an at-risk enterprise customer’s core feature requests in about a month, helping retain $1.6M ARR. I built query persistence across environments.
Built dark mode and the light/dark data viz color tokens for the Lattice design system. Added virtualization, column resizing, and sorting to its tables.
Joined on-call in 11 weeks. Used parallel AI agents to clear all but 3 of 30+ open Dependabot PRs and close 16 security vulnerabilities in 23 PRs, then built Claude agent skills that automate on-call triage and handoff.
Now on the Agent Observability team, building the product views teams use to understand AI agents in production.

Webflow

Senior Software Engineer · Software Engineer, Frontend

Nov 2021 – Nov 2025

Second engineer on Enterprise Workflows. Helped grow the team from 2 to 7.
Frontend lead for the Site Activity Log: 70%+ enterprise adoption and >$50K ARR.
Built Page Branching and Branch Approvals, adopted by 50%+ of enterprise customers and 82% of enterprise partners. Tech lead on standalone branching and activity-log filtering. Shipped Page Templates with the Collaboration team.
Incident Commander for high-severity incidents. Built team observability dashboards in Datadog and OpenSearch.
Member of the CodeGen Adoption Working Group, which rolled out AI dev tools across the engineering org.
Built a testing and mob-programming culture on a remote team, which scored 100% on “connectedness” in the developer-experience survey.

Rover.com

Software Engineer II

Nov 2020 – Oct 2021

Built full-stack features for Rover’s grooming-service expansion (React, Django, MySQL). Improved Datadog and Sentry alerting to cut incident response time.

T-Mobile

Software Engineer

Sep 2019 – Oct 2020

Built Angular/TypeScript tools and Node.js APIs for network-engineering automation, saving thousands of engineering hours and raising tool success rate to 98%.

Marquette University

PhD researcher and teacher

2013 – 2018

30+ publications on accessibility and HCI, with 216 citations, and they’re still being cited in 2026.
Built accessibility-measurement apps, an accessible archive with search, and an SMS health-intervention system.
Taught Python and Java to career changers. Built an IoT demo for the Intel Developer Forum (5,000+ attendees).
