I'm Gagan Kumar, a Software Engineer focused on frontend architecture, AI-powered products, and developer experience. I enjoy building systems where complex workflows feel simple and intuitive to the people using them.

At Astra Security, I design and build the frontend architecture for Attack AI, creating scalable agent-driven experiences, AI Validator integrations, and platform capabilities that improve automation and operational efficiency.

I have led frontend modernization efforts across React 19, Next.js 15, TanStack Query v5, and Tailwind v4, while owning strategic initiatives ranging from dashboard modernization to enterprise customization. I believe great products are built when the user experience and the underlying architecture evolve together.

Impact you can trace.

Work experience, platform initiatives, and engineering milestones that shaped how I build products and solve problems.
