I’m Raihan Rizqullah, a Computer Science student at the National University of Singapore. I’ve worked as a software engineering intern at Binance, GovTech, and Cynapse AI.
I'm building a relational database in C++, with ideas inspired from Postgres and sqlite. I'm passionate about database internals and distributed systems, and currently diving deep into C++. I’ve also built and published several mobile apps
- Relational database implementation: (WIP) Implementation of a relational database in C++ from scratch
- LSM-tree key-val database: Implementation of a write-optimised database using LSM trees, inspired by RocksDB
- MakeMySheet: Convert music audio to music sheet using the Pop2Piano model
- LockedIn: (iOS app) Focus timer that blocks distracting apps and charges you if you try to end your session early
