Most startups fail because their tech can't keep up with their growth. I make sure yours does. I help SaaS founders turn complex ideas into production-ready platforms that don't just work—they scale. With an accelerated degree in Computer Science and 4+ years of "in-the-trenches" experience with rapid-growth startups, I bridge the gap between business goals and technical execution. ❄️ What I bring to your team: ✔️ Zero to One: Architecting MVPs that are ready for Series A/B scaling. ✔️ Performance-First: Reducing latency and optimizing Core Web Vitals to improve user retention. ✔️ Full-Stack Mastery: Specialized in the T3 Stack (Next.js, TypeScript, Tailwind, Prisma) and AWS. Let’s build something that scales. 💪
