Open source, built from real constraints

These projects came out of problems I met while building products: agent email, WhatsApp operations, private photos, browser video, email verification, and owned campaign delivery.

What I’m building now

I’m Sagnik, a product engineer in Pune. Most of my time goes into Autter. I also lead engineering at WorqHat, contribute to open source, and build the infrastructure behind production agents.

    Autter

    Tech creator

    I started building Autter after one too many Friday deploys failed. I’m creating the scanner, product memory, and sandboxed execution system that let Autter review each pull request, run missing tests, check security and product impact, and gate releases on evidence. Autter also traces production failures to the responsible change and opens a verified fix PR.

    WorqHat

    Co-founder · CTO

    I continue to lead engineering at WorqHat, the AI-powered no-code workspace we built for business software and automation. I work on the product architecture and AI infrastructure that let teams create internal tools, customer portals, dashboards, and workflows without starting from a blank codebase.

    Open source

    Code · Documentation

    My open-source work covers code, documentation, and developer tooling. I’ve contributed documentation to Firebase Firestore and Firebase Auth, and I publish fixes or reusable components when product work exposes a problem other developers will hit.

    Agentic systems

    Architecture · Production

    I build agents as software systems, with tool use, memory, permissions, evaluation, observability, and human approval paths. I focus on long-running workflows that coordinate specialized agents, recover from failure, and produce results a team can inspect.

I work across product, systems, and applied AI, carrying ideas from the first architecture sketch through deployment and operation.
