Junjay Tan is a customer-focused software tech lead with 11 years of experience building full-stack web apps, data pipelines, and ML-adjacent systems across startups and large teams including Verily and Google. He combines deep technical chops—debugging complex AI/ML systems, designing resilient data infrastructure, and shipping production services—with hands-on customer engagement across ~100 pilots and expansions, from five-figure proofs to seven-figure enterprise deals. As a tech lead he has onboarded and mentored engineers, driven platform migrations, and been the “last line” fixer for mission-critical launches such as COVID testing and chronic disease enrollment platforms. He’s also an active open-source contributor, having strengthened PAIR-code/facets’ image handling and test coverage, reflecting a penchant for robust tooling and data visualization. Based in Waltham, MA, Junjay pairs analytical rigor from MIT and Brown research stints with pragmatic delivery instincts honed in field-deployed roles and early-stage startup advisories. Outside work he’s a 90s PC gaming enthusiast and parent, a background that hints at both long-term focus and a taste for playful technical tinkering.
