Purelane Storefront

Shipped

A custom Shopify theme for a plant-based homecare brand, built on Dawn with a bespoke homepage over a fixed animated water scene.

Self-hosted fonts, scroll-reveal motion, and reduced-motion fallbacks.

About

Reliability over demos.

Varun Krishna

I'm a full-stack engineer from India. Most of my work lives where software meets consequence: agents that act on real systems, automations a sales team leans on every day, an app many learners carry in their pocket.

The most interesting problem in AI right now isn't making agents capable. It's making them trustworthy enough to leave alone. AgentGate is my running answer to that, and the thinking behind it shows up in everything I build: fail closed, ground every claim in evidence, never trust a model's self-reported confidence.

When I'm not in the editor I write at my blog and build for communities. The best software I've shipped started as someone's daily frustration.

Let's build something worth trusting.

Working on something where an agent, an automation, or a full product actually has to work? I'd love to hear about it. A DM is the fastest way to reach me.
