⬢ THIS IS NOT A PORTFOLIO. IT IS A PROOF.

Everything below runs in your browser, right now. No backend. No libraries. No frameworks. A compiler, a WebAssembly module emitted byte-by-byte, a gzip compressor your own browser validates, a neural network whose gradients are checked against finite differences, a raytracer, an N-body integrator, SHA-256 against NIST vectors, and a regex engine immune to catastrophic backtracking — all hand-written.

And you don't have to take any of it on faith: this page runs its own test suite on your hardware and shows you every result. Open DevTools. Read the source. Every claim here is falsifiable, and set up so you can falsify it.

⬢ FORGE — A REAL COMPILER, LIVE

Lexer → Pratt parser → AST → type checker → constant folding + dead-code elimination → bytecode → stack VM. Statically typed. Rust-style diagnostics with source-mapped carets. Edit the code, hit RUN.

⬢ WEBASSEMBLY — EMITTED BYTE BY BYTE

No Emscripten. No wasm-pack. No wat2wasm. This module was written as raw LEB128-encoded bytes — section headers, type signatures, opcodes — then validated and instantiated by your browser's own WASM engine.

⬢ RAYTRACER — RECURSIVE, FROM SCRATCH

Ray-sphere intersection solved analytically. Recursive reflections, Fresnel falloff, hard shadows from three light sources, gamma-corrected output. Zero graphics libraries.

⬢ N-BODY — SYMPLECTIC INTEGRATION

200 gravitating bodies, ~19,900 pairwise force computations every frame, integrated with velocity-Verlet — a symplectic scheme that conserves total energy where naive Euler integration explodes. The drift number below is measured live.

⬢ SHA-256 — FIPS 180-4, HAND-IMPLEMENTED

Full message schedule, all 64 rounds, correct padding and big-endian length encoding. Verified against the official NIST test vectors below — and against node:crypto on 200 random inputs during build.

⬢ REGEX ENGINE — THOMPSON NFA

Recursive-descent pattern parser → NFA construction → subset simulation with epsilon-closure. Linear time, O(n·m), always. No backtracking, so no ReDoS — ever.

⬢ SORTING LAB — INSTRUMENTED

Median-of-three quicksort with tail-call elimination, top-down mergesort, and an LSD radix sort — benchmarked against V8's native TimSort on identical data, with correctness verified after every run.

⬢ DEFLATE — A GZIP COMPRESSOR, AND AN INDEPENDENT REFEREE

RFC 1951 and RFC 1952 implemented from the spec: an LZ77 sliding window with hash-chain match search, canonical Huffman coding length-limited to 15 bits, dynamic / fixed / stored block selection by actual bit cost, run-length-coded code-length alphabets, and CRC-32. No pako, no fflate, no zlib.

Anyone can claim their compressor works. So the output is handed to DecompressionStream('gzip') — your browser vendor's decoder, not mine. One wrong bit anywhere in the Huffman stream and it throws. Download the result and run gunzip on it if the page still isn't convincing.

⬢ NEURAL NETWORK — BACKPROP DERIVED BY HAND

A multilayer perceptron training live on the two-spiral problem — the benchmark no linear model can ever solve. Xavier initialisation, tanh hidden units, sigmoid output, binary cross-entropy, mini-batch SGD with momentum. Every partial derivative in the chain rule is written out explicitly. No TensorFlow, no ONNX, no WASM blob.

The claim that matters is not the animation — it is that the gradients are right. This compares every analytic gradient against a central finite-difference estimate of the same derivative:

⬢ CONTINUOUS INTEGRATION — RUNNING IN YOUR BROWSER

Every other portfolio asks you to take its word. This page runs its own test suite in front of you, on your hardware, right now. 40 assertions against values fixed before the code existed: NIST vectors, known Fibonacci numbers, your browser's own gzip decoder, finite-difference gradients, conservation of energy.

If any row below turns red, a claim on this page is false. That is the whole design. Nothing here is a screenshot.

⬢ UPSTREAM — WHAT ACTUALLY LANDED

The engines above prove I can build. This proves other maintainers merged it. Status is the real GitHub state — nothing upgraded for effect. Every row links to the diff.
