We have been using graph DBs more and more at work. I found them painful to work with locally and decided to try and build something better.

Could you build this?
No Designing an embedded, file-based ACID-compliant graph database engine from scratch requires deep database internals, disk storage layout, and query engine expertise.
What it would actually take: A SQLite-equivalent graph DB requires implementing a custom storage engine (e.g., B+ Trees or LSM trees mapped to disk files, or layered over LMDB), write-ahead logging (WAL) for ACID transactions, and a graph query engine (handling Cypher or openCypher). Graph-specific query optimization (like worst-case optimal joins and index-free adjacency) requires substantial knowledge of computer science graph theory and database systems engineering.
