BRANDENRIVERA.

Built a single-file database engine from scratch in C17 with 4 KB pages, explicit binary serialization, a page cache, and an arbitrary-height B+ tree supporting full CRUD and O(log n) key lookups.

Implemented CRC-32 page validation, ordered fsync commits, a redo write-ahead log, idempotent requests, file locking, and multi-statement transactions; verified with 160+ tests, fault injection, randomized testing, and sanitizer-backed fuzzing.

Built an LLM coding agent that executes multi-step software tasks through structured Read, Write, Delete, and Bash tools using an iterative tool-calling loop with runtime and execution limits.

Created an 18-task evaluation harness comparing three models across six task categories. The FastAPI and SQLite application persists conversations, handles provider fallback, explains routing decisions, and includes 62 automated tests.

A Pokémon Showdown project built around a FlyWire-derived fruit-fly connectome. The model will encode battle states, propagate sparse neural activity through a biologically constrained network, and decode legal moves and switches.

The initial milestone is behavior cloning recorded Gen 1 OU decisions, comparing the connectome-constrained policy with control topologies, and visualizing battle and neural telemetry in a web interface.
