Second year computing science at the University of Alberta. I write low level systems from scratch to find out what is underneath the abstraction: an allocator instead of malloc, Raft instead of a database that already handles consensus, a rasterizer instead of a graphics API.

None of it is better than the real thing. That was never the point. The point is that afterwards the real thing stops being magic, so when it behaves strangely you have somewhere to start.

A fully local autonomous voice assistant. Sub-600ms bidirectional speech with barge-in, OS level machine control, dual layer persistent memory over a knowledge graph, and a WebGL holographic HUD. It boots offline with no GPU, no model download and no credentials, then swaps in real backends behind traits.

The design premise is that the model is an untrusted planner. Actuation lives in a separate privileged daemon that recomputes the required capability from the operation itself, gates irreversible actions behind confirmation, and audits everything.

github.com/apollo-2006/oracle-of-delphi · try the HUD in your browser (scripted core; the real one needs a local GPU)

Every demo runs the project's own code in your browser: C and C++ compiled to WebAssembly, Python under Pyodide, TypeScript and JavaScript as written. GitHub Actions builds each one from its repository and publishes it to Pages. Click a card to open it.

oracle-of-delphi the real HUD of the assistant above, with a scripted core standing in for the local GPU	nexus_cluster Raft from the paper, with a simulation that checks the safety properties at every step
nexus_db LSM key value store: skip list memtable, write ahead log, SSTables and tombstones	nexus_editor collaborative editing on a fractional index CRDT with string positions and tombstones
nano_match limit order book, no allocation after startup: 12M requests/s at a 50ns median on one core	custom_mem_alloc allocator over one mmap region: first fit, splitting, neighbour coalescing, benchmarked against glibc
neon_vm stack based bytecode VM with bounds checked single step dispatch and a step through debugger	photon_tracer path tracer with no libraries: 1080p at 50 spp in half a second on 32 threads
cpu_rasterizer a full 3D pipeline in plain JavaScript with no graphics API, 0.43 ms a frame	rasterizer_engine the same idea in C++ and SDL2: culling, flat shading and a depth buffer on the CPU

Pull requests to open source projects. About half fix memory safety bugs or crashes, found with sanitizers and Miri. The badges show each one's live state on GitHub, and abirdeol.tech/work has the reasoning behind each.

whisper.cpp #4031	the tests aborted on any GGML_BACKEND_DL=ON build: no backend registers until something calls ggml_backend_load_all(), and the tests were the only callers that did not. found it, fixed it in four call sites
whisper.cpp #4064	heap out of bounds read when a VAD model declares any encoder layer count but four, reachable from whisper-cli --vad
candle #3965	heap overflow in Tensor::from_raw_buffer, reachable from safe code: a seven byte f32 buffer wrote past its allocation and returned Ok
candle #3963	undefined behaviour loading quantized GGML tensors, a byte slice cast to blocks with no length or alignment check
tokenizers #2398	a malformed BPE merge list produced invalid UTF-8 through from_utf8_unchecked; the fix removes the unsafe block
espeak-ng #2530	an unsigned subtraction read before a heap string on ordinary voice selection, on nearly every run, found under UBSan
espeak-ng #2537	a zero length phoneme data file crashed the process through a NULL buffer no caller checked
pdf-rs #296	a PDF declaring a function domain backwards panicked the parser
pdf-rs #295	encrypted files from some producers could not be opened with any password, because /P was written as an unsigned 32 bit integer
llama.cpp #28462	a release tarball unpacked inside any other git repository stamped that repository's commit into --version
espeak-ng #2529	-Wimplicit-fallthrough for the thousand line language table, where a missing break silently gives one language another's settings
whisper.cpp #4047	the CI leg that would have caught #4031 before it shipped
whisper.cpp #4029	prebuilt macOS binaries, including a lipo fused universal archive that picks its CPU backend at load time
whisper.cpp #4019	documented the stream example's two output formats, and the working directory relative model path that surfaces as an init failure

• valo_scout   Valorant match analyzer, ranking games on combat and utility with a hand written heapsort
• radiant_slice   tactical FPS systems in Unreal Engine 5 C++: counter strafing, spray patterns, lag compensation
• personal_portfolio   abirdeol.tech, built from scratch

Four of the projects above had a bug that cost me real hours. I wrote each one up afterwards: the symptom, how I chased it, what was actually wrong, and what I changed about how I write that kind of code.

• The block that was too small to free   an intrusive free list corrupting the block next door
• The delete that did not delete   a flush optimization that resurrected deleted keys
• The order that was in two places   a use after free that never crashed
• A cluster that could not keep a leader   when the runtime pauses longer than your failure detector waits

Working through machine learning from classical computer vision upward, and writing down what I learn rather than collecting tutorials. Two time national MMA champion, 2020 to 2024. Looking for software engineering internships.
