About me

I am a Software Development Engineer and product founder who builds tools to solve real-world inefficiencies.

I currently operate Wrath Labs, a sandbox for technical innovation where I build and iterate on experimental product ideas. My focus right now is directed toward a major, unannounced project that is currently in the early stages of development.

Previously, I founded Cooketh Company, a development studio where I shipped B2B and B2C platforms spanning immigration, employment, and writing industries. During this time, I also built and released Cooketh Flow, an open-source visual thinking application.

I strongly believe in the power of developer communities. What started as organizing campus-level events evolved into leading city-wide initiatives, including organizing official FOSS Meetups in Kolkata to champion open-source software.

When I am not building products or communities, I spend my time reading about self help, psychology, finance, and history, or exploring new music.

What I'm doing

  • SaaS & Product Development

    Architecting and engineering scalable, cross-platform applications from 0 to 1. Focused on delivering high-performance, end-to-end solutions that drive real business value.

  • Tools & Open Source

    Building intuitive developer tools and open-source software designed to optimize creative workflows and solve complex technical inefficiencies.

  • Technical Writing

    Crafting clear, comprehensive technical documentation, architecture guides, and engineering articles that bridge the gap between complex code and user understanding.

  • Community Building

    Fostering vibrant developer ecosystems through tech evangelism, organizing city-wide open-source meetups, and championing collaborative engineering cultures.

  • Music & Audio

    Exploring the creative process through music. Always open to connecting over audio production, lyrical breakdowns, or collaborative creative projects.
