SeniorZack 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%.
