Identity

I'm Karan Chourasia, a software engineer with a frontend focus who cares about the space between an idea and how it feels when someone actually uses it.

I design and build interfaces that are clear, responsive, and thoughtfully crafted. I care about how products behave, how systems scale, and the small details people may never consciously notice but immediately feel when they're missing.

My work sits at the intersection of product experience and resilient engineering, turning ideas into interfaces and systems that are built to last.

A closer look at the engineering problems behind the work, the decisions that solved them, and the systems that emerged.

Authentication architecture

Building an Auth0 BFF architecture for Product

01

The problem

The platform needed one secure authentication boundary across a React frontend, backend APIs, agent services, integrations, organization access, RBAC, and audit requirements.

Designing a secure PAT architecture for Product

02

The problem

CLI clients, automation, and external integrations cannot use a browser session, but still need durable API credentials that are revocable, scoped, auditable, and isolated to an organization.

The work behindthings thatjust work.

Infrastructure

I care about what happens after a feature ships: whether teams can see what their systems are doing, catch trouble early, and spend less time on repetitive fixes. That is the infrastructure work I enjoy most.

career history

What shaped my work.

A record of product development, frontend systems, and technical operations.

  • Contributed to the development and maintenance of 5+ internal solutions and customer-facing products.
  • Led frontend development for two core, ongoing products, working closely with product managers and backend engineers to ship features, refine workflows, and improve overall system reliability.
  • Enhanced application performance by up to 30% through code splitting, caching strategies, bundle size optimization, and minimizing unnecessary re-renders.
  • Integrated RESTful APIs and AI-driven model outputs into frontend workflows, improving data flow efficiency and responsiveness across dashboards and interactive components.
  • Improved cross-device responsiveness and accessibility by building reusable UI components and maintaining clean, modular, and scalable frontend architecture.
