Projects

Personal Site (rayhan.id)

Initially made as an excuse to learn MPA with Astro, but end up becoming my personal site. I try new stuff once in a while, ranging from animations, frontend optimisation, CI/CD, and more.

Tech Stack: Astro, React,GSAP, GitHub Actions, Nginx, and more.
Unwind

A mobile application to help people track their productivity while maintaining their mental wellbeing. I was responsible for the system architecture, model the database, developed the login and register page, and fixed various UI-related bugs and issues.

Tech Stack: React Native, Expo, and Firebase.
Modern Data Lake Architecture Exploration

I explored the modern data lake architecture. Generating TPC-H data, storing data in S3, querying data with an query engine, and using dbt to transform the data. I learned a lot about the configs and tinkering needed to make them work together.

Tech Stack: Iceberg,DuckDB, R2, Snowflake, dbt.
Lynkr - URL Shortener

Designed for small-to-medium organisations who need to self-host their own URL shortener. Intended to be feature-rich while still being fast, lightweight, and easy to deploy. Learned a lot about authN by following the OWASP guide for security, ranging from password storage, email verification, stateful session, CSRF, and more. Currently still in development.

Tech Stack: Fastify, React, PostgreSQL, Redis, and more.
