Sathish Raja
@sathishraja
Senior software engineer specializing in Node.js, React.js, and cloud-native full-stack delivery for remote teams.
SingaporeWhat I'm looking for
I’m a Senior Software Engineer and Full Stack Developer with 12+ years of international experience delivering full stack web applications, enterprise integrations, and cloud-native platforms across Singapore, Hong Kong, and India. I’m especially effective in remote, async-first environments where clear communication and dependable execution matter.
At Konica Minolta Business Solutions Asia, I design and integrate enterprise applications for robotic automation workflows, containerizing and deploying production systems with Docker. I reduced deployment errors by 50% through optimized containerization workflows, and I’ve architected RESTful API integrations supporting mission-critical AMR and fleet management platforms.
I continue to build and evolve products that stay reliable across distributed codebases—using Node.js and TypeScript, and focusing on scalable, maintainable architecture. For example, I increased API transaction processing speed by 40% through strategic API architecture design and backend performance optimization, while collaborating asynchronously with cross-functional engineering teams.
My work also spans real-world automation and public-facing solutions, including architecting configurable robot automation platforms (sWorkflow) and delivering real-time robot monitoring dashboards (sConnect). I bring a strong documentation and system-design mindset—producing clear API docs, onboarding guides, and technical writing that helps remote teams move faster with fewer integration issues.
