What I'm looking for

I’m seeking a senior engineering role building AI-driven, scalable systems in a collaborative, fast-paced team where I can lead architecture, improve automation, and deliver measurable performance and user-experience gains.

I am a passionate Full-Stack Engineer and AI/ML specialist with 12 years of experience building scalable, high-performance solutions. I thrive on turning complex problems into efficient systems that improve accuracy, automate workflows, and optimize performance.

At Kore.ai I designed and built an AI-powered virtual assistant that scaled to millions of daily interactions, engineered an NLP pipeline that boosted intent recognition accuracy to 95%, and reduced average handling time by 15% while automating 75% of customer inquiries. Previously I engineered scalable microservices and HIPAA-compliant systems, improved application performance by 60%, and implemented CI/CD pipelines enabling 30+ deployments per day.

I enjoy working in fast-paced environments where I can design efficient architectures, streamline processes, and create seamless user experiences. I focus on pragmatic, measurable outcomes—whether improving engagement with React/Next.js front-ends, optimizing backend services with Node.js/Python, or deploying resilient infrastructure on AWS and Kubernetes.
