Summary
Zack Babtkis is a Senior Software Engineer in Los Angeles with 12 years of experience building high-impact web and extension products across ad-tech, fin-tech, ag-tech, GIS, and marketing platforms. He specializes in JavaScript (vanilla and modern frameworks), Ruby, Elixir, and microservice architectures, and has a track record of rapidly delivering testable features in agile teams. At PayPal he led browser-extension efforts that preserved and grew multi-million dollar revenue streams, invented re-engagement patterns that boosted mobile extension revenue ~25% in two weeks, and drove unit test coverage from 0 to 90%. He’s comfortable across front-end UIs and backend systems, having designed real-time tracking services and CI/CD pipelines at scale. Known for clear communication and user empathy, he also mentors engineers and shapes product-technical coordination. A less obvious strength: he balances deep technical refactors with pragmatic product thinking to protect revenue while enabling long-term maintainability.
