Prerak Mathur
Developer + Full-Stack Engineer, Frontend Developer, Backend Engineer, Product Engineer, Swift Developer, Open Source Contributor, and Problem Solver
Hi there
I'm Prerak, a frontend-focused engineer at Nutanix with 3+ years building production systems end-to-end. React, TypeScript, and Next.js are where I do my best work, backed by Go, Java, Spring Boot, Kafka, and containers when a feature needs to reach all the way down. I care deeply about component architecture, system design, and performance.
Outside of work I build Sokket, a free macOS app for seeing and controlling everything running on your ports, and maintain Tokis, an open-source React UI library with 500+ weekly downloads. I also contribute to Internet Archive and CircuitVerse, and I'm a Codeforces Specialist and Google Summer of Code 2022 contributor. Always happy to chat about frontend engineering, developer tools, or open source!

Where I've worked
- Built an internal analytics dashboard (React, TypeScript, GraphQL) with Redux state management and lazy-loaded modules — reducing on-call reliance by 40% and cutting initial bundle load time by ~35%.
- Designed reusable React component library and data-fetching patterns adopted across internal tooling, enforcing consistent UI contracts and accelerating feature delivery.
- Automated data re-ingestion and audit workflows on GCP via Java and Kafka, eliminating 10–12 DevOps hrs/week and reducing manual operations by 75%.
- Contributed to Walmart’s catalog aggregation backend — reactive Kafka + Cassandra services with 35% peak surge reduction monitored via Grafana.
- Built a returns lifecycle tracking dashboard (React, GraphQL, Axios) with real-time order status UI and Redux state management, cutting ticket resolution time by ~30%.
- Built dependency management tooling and secure CI/CD identity key generation for Walmart’s internal platform, improving access governance and security.
- Architected a Java Spring Boot gateway filter enforcing authorization policies for sensitive internal APIs, preventing unauthorized downstream access.
- Developed SEO-optimized web apps and admin dashboard with Next.js SSR, building responsive, accessible UI components and improving Core Web Vitals across devices.

Tokis – Open Source React Component Library
A React component library where switching themes costs zero JavaScript. Design tokens live in CSS custom properties, every component implements its full WAI-ARIA pattern, and importing one button ships one button. 500+ weekly downloads on npm.
Sokket – Own Your Localhost
A free macOS app that tells you what is on every port — named by project, not process ID — and lets you kill, forward, watch and record it in one click.
Drone Development & Data Classification
A government-funded drone built to cost a fraction of the commercial equivalent, flying Indian farmland and spotting crop stress on board before it is visible from the ground. Open source, patent pending.
