Finished a focused backend cleanup and optimization project on Contra.

This project was about improving an existing Node.js / Express / PostgreSQL backend by reviewing the codebase, identifying issues, cleaning up structure, improving API reliability, strengthening error handling, testing key workflows, and documenting the changes clearly.

A good backend is not only about adding new features — it is also about making the system easier to maintain, more stable, and ready to scale.

Stellar Dungeon — a 2D dungeon crawler built in Godot 4.4 for the Argentina Builder Challenge 2026, with on-chain progression over the Stellar network. I contributed the backend blockchain integration: a Node.js relay and a Rust smart contract (forge_ledger) that log mining, crafting and forging on-chain, with per-player custodial wallets and an offline sync queue.
