About

I build software and ship it.

I'm Siddhesh, a software engineer in Mumbai. I work on products people can install, open, or integrate: SaaS applications, developer tools, and the delivery systems around them.

At Cyber Managers Software Services I work on Encatch, the team's SaaS feedback platform. My part of that is the admin panel, the public website, a Web SDK published to npm, and deployment automation around the product.

On my own I build and maintain open-source software. TabWise is a Chrome extension for tab and session management, published on the Chrome Web Store. GetSecret is a platform for sharing a secret once and letting it expire. I take both of them from the idea through to a public release, and I keep maintaining them.

Most of my shipping work is frontend and full-stack: React, TypeScript, Next.js, NestJS, PostgreSQL, and Redis. Cloud infrastructure — AWS, Docker, Kubernetes, and CI/CD — is an area I am actively developing through the deployment work I already do.

Engineering journey

  1. Associate Software Engineer

What shapes the work

I care about software that changes how someone works. If a feature does not do that, it does not need to ship.

Developer experience shows up in the tools I publish. The GetSecret SDK and the Encatch Web SDK came from the same constraint: the integration should be smaller than the problem.

I pay attention to architecture when it keeps a system understandable, and to cloud infrastructure because deployment is part of the product. I use AWS, Kubernetes, Docker, and CI/CD in that work, and I am building more depth there as I go.

Open source is where I finish things in public. Product engineering is the filter on top of it: what problem, for whom, and what can stay out.
