Rockstar🎓
Top SchoolErnie Park is a product-focused software engineer and founder with 14 years of experience building growth-oriented products and teams at companies like HubSpot and Brex, and now leading consumer and community ventures including Lizzy Sleep and Part-Time Tech. He blends hands-on full‑stack engineering with engineering leadership—scaling freemium monetization, running growth experiments, and hiring and coaching teams—to turn product insights into revenue and retention. Since stepping away from full‑time roles he’s consulted for startups as an interim Head of Engineering, launched a newsletter/podcast ecosystem for part‑time tech, and founded a sustainable family farm aimed at local social impact. Comfortable switching between shipping code, shaping strategy, and organizing operations, he’s motivated by work at the intersection of tech, philanthropy, and sustainability and brings practical founder instincts rooted in MIT technical training.
