Summary
👤
Senior🎓
Top SchoolVincent Lonij is a software engineering leader and former founder with eight years of startup-focused experience and a deep research background, currently directing full-stack and AI engineering at Lone E from Ireland. He builds MVPs and scalable products by aligning user need with pragmatic engineering — prioritizing agility and small-team execution over premature scalability. Previously he founded and raised over $1M for Swyg, an AI-powered peer-to-peer video interviewing platform that reduced hiring bias, and led engineering at SkillsTrust on pay-transparency products. His earlier career blends applied AI and forecasting at IBM and Bloomberg with academic PhD work in atomic physics, giving him rare strengths in turning complex data and models into production systems. Colleagues value his mix of hands-on coding, product sensibility, and the ability to shrink AI iteration cycles from weeks to hours.
