The Amend Standard

Built On Uncompromising Principles

Every tool we release must satisfy three strict rules before entering our production fleet.

1. Client-Side Privacy First

Sensitive numbers—whether they are confidential profit margins, supplier costs, or Canadian personal income figures—belong exclusively to the user. We perform calculations in the user's browser, eliminating unnecessary database tracking and liability.

2. Instantaneous Zero-Lag UX

Tools should feel like an extension of your thought process. Sliders, inputs, and toggles recompute instantly without spinning loaders. Our web code delivers optimal Core Web Vitals and lightning-fast Largest Contentful Paint (LCP).

3. Utilitarian Craftsmanship

We build software that solves a clear, acute problem. No bloated marketing fluff, no artificial lock-in, and no unnecessary friction. Just clean, reliable, beautifully designed software tools that work every single time.

Studio Leadership

Vaibhav Purohit

Founder • Lead Product Architect

I founded Amend Technologie with a singular mission: to create independent digital products that bring clarity, mathematical accuracy, and joy to people's daily lives and businesses.

Instead of relying on generic service models, we focus our energy on shipping real products—from the 29+ seller tools in KleverKlimb to the CRA-grade tax calculation algorithms in MyTaxCalculator.ca. Everything we create is crafted with care, high technical standards, and relentless user focus.
