Full Stack Software Engineer building scalable, high-performance web apps with React, AWS, and Spring Boot.
Sri LankaWhat I'm looking for
I’m a results-driven Full Stack Software Engineer with 2+ years of experience delivering scalable, high-performance applications. I focus on React and TypeScript frontends, resilient backend services with Node.js/Python/FastAPI and Spring Boot, and cloud-native implementations on AWS.
In my current role, I’ve automated PDF-to-SVG conversions with AWS S3 and Lambda—cutting manual processing time by 80%—and built tools that materially improve accuracy and productivity. I also enhanced estimation workflows (e.g., “Filter by Measurement”), implemented custom in-app search to reduce lookup time by 50%, and integrated AI-powered estimation components using Python to cut repetitive work by 40%.
I work end-to-end: improving UI performance by migrating dashboards from Angular to React (reducing bundle size by 35%), engineering precise drawing/annotation logic with Konva.js, and developing secure, fast services (FastAPI and microservices with REST APIs). I’m energized by building real-time and user-focused features—like WebSockets-driven updates—and by reducing operational cost through serverless design.
