Multiple Hermes App Screens

Hermes

While this app is named for the Greek god of messages, Hermes is a mobile news app built with React Native and Expo that delivers real-time news from the New York Times API. This was designed with an editorial aesthetic heavily inspired by the NYT masthead, the high-contrast serif typography, a strict black and red palette, and fluid animations throughout. Hermes v1.0.0 features a hero feed with category-based browsing, debounced keyword search, article bookmarking, an in-app WebView reader, skeleton loading states, and error handling with retry support. Built on a clean feature-based architecture with a normalized API layer, TanStack Query for server state, and Reanimated 4 for UI-thread animations.

Athena

Athena is a mobile app that lets you listen to any book read aloud in your own cloned voice.

Portfolio Website

My Portfolio

This is my personal portfolio website or as I'd say - the portfolio to end all other portfolios on my part. It was created to solve a problem I kept running into, which was constantly updating my portfolio by interacting with the codebase when needed. Hence, I designed the site to be fully content-driven. I built it on Next.js with Sanity CMS for handling all the content, styled with Tailwind CSS and shadcn/ui for a clean, consistent UI, with Motion powering the animations and transitions throughout. Beyond the portfolio itself, the site has a fully functional blog, a live GitHub heatmap that pulls my real contribution data straight from the API, a gallery filled with memories of mine, as well as a spotify widget.

codestreak

CodeStreak

This was a project I thought I’d build after reading Atomic Habits by James Clear. The main purpose was to build something that’ll help foster good coding habits by making them attractive. And thus, came CodeStreak. CodeStreak is a community-driven platform designed to empower software developers through consistent coding habits. Track your streaks, share progress, and stay accountable with a community that keeps you moving forward.
