What I'm looking for

I’m looking to build scalable AI-powered full-stack products, collaborating cross-functionally to ship high-impact features—optimizing performance, automation, and data-driven solutions.

I’m a highly skilled full-stack developer and AI engineer with 14+ years of experience designing, developing, and deploying scalable web applications and intelligent systems. I build responsive, performance-optimized user experiences and integrate AI capabilities into real-world products using modern front-end and back-end technologies.

I architect AI-powered full-stack platforms and lead integrations of LLMs, NLP systems, and automation tools—improving performance by 35% and reducing latency by 40%. I’ve also managed AWS/GCP infrastructure to optimize costs by 25% while supporting 99.9% uptime, and delivered end-to-end AI-driven SaaS solutions that increased user engagement by 20% and retention by 15%. From machine learning to production deployment, I’ve built and deployed models (TensorFlow/PyTorch), reduced preprocessing time by 40%, and cut inference time by 35%.
