Summary
🤩
Rockstar🎓
Top SchoolErik Ljungman is a Full Stack Engineer in Astoria, Oregon with eight years of experience building user-focused web and embedded systems across startups and research teams. He blends a physics and computer science background from the University of Michigan with hands-on work in front-end visualizations, network validation tools, and IoT/automotive telemetry—often partnering directly with clients to shape features. At Intentionet he helped visualize and simulate network changes (contributing to Batfish), and at Voyomotive he developed mobile and BLE solutions tied to vehicle CAN/OBD-II systems. Currently at SwingVision he continues shipping full-stack products that sit at the intersection of real-time data, UX, and backend reliability. His profile reflects a maker’s curiosity—equally comfortable writing parsers and ANTLR rules, crafting d3 visualizations, or prototyping hardware-connected software.
