What I build ---

I build web platforms that scale. With over 4+ years of experience, I specialize in building multi-tenant SaaS platforms that handle real-time video, biometric assessments, and high-stakes interactions — without breaking. I don't just build features; I design deterministic systems where every state transition is intentional, and every feature toggle is tenant-aware.

Key highlights: Boosted React app performance by 40% and achieved Lighthouse 90+ scores by eliminating legacy libraries and building custom components. Reduced cloud infrastructure costs by 70% by migrating Azure VMs to App Service with automated CI/CD pipelines. Built a real-time computer vision pipeline (MediaPipe) with 95%+ production accuracy, featuring adaptive frame rates and multi-person detection.

I design for worst-case scenarios — building scalable SaaS systems with predictable state transitions, resilient lifecycles, and reliable asynchronous workflows. Check out my projects to see it in action.
