What I'm looking for

I'm looking for remote opportunities where I can build reliable backend, data, and AI-enabled products end to end, from system design through production support.

At Mphasis, I build production backend and AI systems for healthcare, financial services, and internal enterprise platforms. My work spans APIs, data processing, integrations, cloud infrastructure, and user-facing operational tools.

I've improved response times by 47% while maintaining 99.9% availability, and built terabyte-scale integration workflows that increased throughput by 32%. I also developed document-processing systems that reduced manual review by 38% and achieved 94% accuracy on targeted structured fields.

I build retrieval-based and agent-powered enterprise applications, including conversational search, document retrieval, decision support, and workflows that connect natural-language interfaces to databases and business tools. These systems improved answer accuracy by 23% and reduced retrieval latency by 43%.

Previously at Nike, I delivered manufacturing, supply-chain, retail, and athlete-facing software, including predictive-maintenance, computer-vision, recommendation, and data-pipeline capabilities. I enjoy owning systems from design through deployment, monitoring, and production support.
