I build production AI platforms and high-performing full-stack products with Python, React, Azure, and PostgreSQL.
Sri LankaWhat I'm looking for
At Nimbus LABS, I co-designed Aura, a six-agent AI platform for real-estate reporting, market analysis, and specialist workflows. I build across Next.js, Python/LangGraph, PostgreSQL, and Azure.
I reduced AI report-generation cost by about 82% while maintaining or improving evaluated output quality, and built asynchronous report-generation systems using Azure Service Bus, Container Apps, and APIM. I also introduced feature flags, automated secrets distribution, CI/CD validation, and staged deployment controls to support a reliable weekly release cadence.
Previously at Sysco LABS, I modernized the live Sysco Shop frontend from React 15 to React 19 and Webpack 5, improving page performance and reducing production defects. I’ve owned product experiences, mentored engineers, and built cloud-native applications with Python, React, AWS, Docker, Jenkins, and Grafana.
