Building scalable web experiences
A passionate Full Stack Engineer with 5+ years of experience crafting performant web and mobile applications. I specialize in React, Next.js, and TypeScript, with deep expertise in Node.js and cloud technologies.
On the side I build and run products, and put out open-source tools when a problem keeps bugging me.
Hey, I'm Muthaiyan 👋
I'm a Software Engineer with 5+ years of experience building scalable web applications. I care about clean code, great user experiences, and shipping products that actually work.
Currently, I work at Delightree as a Senior Frontend Engineer, owning the frontend architecture and driving web performance for a franchise operating system. Previously at Catalyst by Zoho, where I built a Generative AI product, a frontend hosting microservice, and developer tooling used by thousands of developers.
I love coding in my free time and constantly seek opportunities to learn, collaborate, and work on new projects with like-minded people.

My Work
A collection of projects I've built over the years. From open-source tools to enterprise-grade platforms, I love solving complex problems with elegant solutions.
A habit tracker I built and run as my own product. Set a goal, keep the streak alive, and watch the progress add up week over week.
Bookkeeping for small shop owners who still run their accounts on paper. Track daily income, expenses, and vendor dues right from a phone.
Generative AI App Builder
A product I built at Zoho that turns plain prompts into working apps. AI responses stream in real time, get parsed on the client, and the generated code runs in a live preview right in the browser.
A CLI that gets GitHub, GitLab, and Bitbucket webhooks into machines sitting behind a firewall. It opens an ngrok tunnel and forwards the events for you.
A TypeScript SDK that takes token refresh, expiry, and persistence off your plate, with pluggable storage strategies. Wire it up once and stop thinking about OAuth.
Sends a WhatsApp message to a long list of recipients in one go. It drives WhatsApp Web with Puppeteer, so there is no paid messaging API involved.
