Hi, I’m Junde Fong, a senior full stack engineer based in Singapore with 7+ years building cloud-native, distributed, data-intensive web and mobile products. I specialize in scalable APIs, microservices, MLOps, and data privacy in multi-tenant environments, and I enjoy collaborating closely with product, data science, and domain experts in Agile teams. Most recently, I delivered an AI+GIS powered crop-monitoring platform that fuses satellite imagery, weather data, and spatial analytics to improve yield prediction and disease detection. This work included production ML, real-time advisory workflows, and robust security and observability practices. I’m driven by practical engineering that ships reliably at scale while enabling data-driven decision making for real-world impact.…Hi, I’m Junde Fong, a senior full stack engineer based in Singapore with 7+ years building cloud-native, distributed, data-intensive web and mobile products.
