Computer Science
I like building things that people actually use. Most of my work sits at the intersection of design and engineering, where small details shape how something feels. When I'm not writing code, I'm usually out with a camera shooting street and architecture.

RustTokioserde
A persistent key-value database engine written in Rust. Explores low-level storage primitives, memory-safe concurrency, and the trade-offs behind building reliable data infrastructure from scratch.
- Write-ahead log (WAL) for crash recovery and data durability
- In-memory memtable with sorted key ordering for fast lookups
- SSTable-based persistent storage with binary search reads
- Async I/O with Tokio for concurrent client connections

Solo Developer
C++
A lightweight database engine that parses SQL queries, plans execution, and runs them against a page-based storage layer. Supports CREATE TABLE, INSERT, and SELECT with WHERE clauses.
- Hand-written recursive descent SQL parser with tokenizer
- Query planner that generates execution plans from AST
- Page-based storage engine with fixed-size record layout
- Full pipeline from raw SQL string to query result output
