Building Production-Grade
Backend & AI Systems

Scalable APIs • Intelligent Automation • Real Business Solutions

I design and deploy backend systems and AI-powered workflows that drive real business value. From async task queues to machine learning pipelines—infrastructure built to scale, deployed with confidence.

What I Build

Production systems that solve real business problems

I specialize in building backend infrastructure and AI systems that power real products. My focus is on reliability, scalability, and maintainability—the foundations that keep applications running smoothly under real-world conditions.

From RESTful APIs serving thousands of requests per minute to async task processing systems handling background jobs at scale, I architect solutions with production readiness in mind. My work includes integrating machine learning models into production workflows, building data pipelines, and deploying systems that stay up.
