Performance Optimization (Locable)
Reduced API response time by 85% (from 8,000ms to 1,200ms) using k6 load testing and refactoring data-fetching logic to serve geospatial points directly via .geojson files.

Hi, I'm Jatuwit.
I build scalable systems and intelligent applications.
7 years of experience architecting robust platforms, optimizing performance, and integrating AI solutions.
About Me
I started as a Java Developer at Godygo, building backend APIs for logistics applications. That foundation led me to Avalant, where I evolved into a Full Stack Developer and later Senior Full Stack Developer—spearheading frontend architecture for platforms like "Zero" (No-code) and "PromptX" (AI-driven interface) with React.js and TypeScript.
I'm passionate about performance. At Bedrock Analytics, I reduced API response time by 85% (from 8,000ms to 1,200ms) using k6 load testing and refactoring data-fetching to serve geospatial points via .geojson files.
Today I focus on AI integration—RAG, Vector Databases, and building intelligent applications that scale. I'm seeking an impactful role to drive innovative software development.
