Angelin John

Since 2017, I have operated at the intersection of complex engineering and startup strategy. As a Tech Lead, I specialize in Structured Thinking—deconstructing high-stakes domains like Fintech, Robotics and CyberSecurity into scalable products and high-performance systems. I don’t just ship code; I build the technical and business frameworks that allow startups to scale, aligning full-stack craftsmanship with GTM outcomes. I am a relentless student of 1% daily compounding growth, whether I'm mentoring teams, architecting architecture, or exploring the business side of the startup lifecycle. ✍️ I share my frameworks on deconstructing startups at Building the Builder on Substack.
