Biography

Hello, I'm Manoj S, a Full Stack Software Engineer with 3+ years of professional experience engineering high-performance web applications across the full application lifecycle using React.js, TypeScript, JavaScript, and Node.js. I specialize in architecting API-driven client-server workflows, server-state caching, secure JWT/RBAC authorization, and LLM-powered streaming user experiences.

At Zlendo Technology, I have delivered scalable solutions across full application scope—from 2D/3D visualization platforms with Three.js and Konva.js to multi-tenant contract management systems with TanStack Query and OnlyOffice, and enterprise HRMS platforms serving 10K+ daily active users.

My engineering background bridges frontend architecture (Material UI, Tailwind CSS, Storybook), backend APIs & auth (Node.js, Express, REST APIs, Webhooks, JWT/RBAC), databases (PostgreSQL, MongoDB, SQL), and cloud/DevOps practices (AWS, Docker, CI/CD). I prioritize web accessibility, performance optimization, and rigorous testing with Jest and Cypress.
