Jagger Brulato
01 / ACTIVE DOMAINProduct

Interfaces, behavior, and resilient user flows.

Main laneFull-stack
Favorite workProduct
Also intoPlatform + PL
Start HereOJaml

01I’ve worked at Google, startups, platform teams, and product teams.

02I can lead the work, make technical decisions, write the code, mentor engineers, and keep the system understandable as it grows.

03My side projects follow the same pattern: languages, runtimes, compilers, simulations, games, compression, renderers, and backend utilities.

01 — What I do

Senior engineering across the whole product.

I connect user experience to the services, data, infrastructure, and tools behind it—then keep the result understandable as it grows.

01

Product

Interfaces people understand, backed by deliberate behavior and resilient flows.

02

Platform

Systems that help teams ship, observe, and operate software with less friction.

03

Craft

Clear boundaries, pragmatic architecture, and code built to change.

04

Leadership

Direction and mentorship without drifting away from implementation.

01

OJaml

An OCaml-inspired language and compiler built end to end in TypeScript with lexing, recursive-descent parsing, Hindley-Milner-style inference, polymorphic functions, signature-checked modules, structural patterns, polymorphic collections, ADTs, records, tuples, and WebAssembly emission.

  • OJaml
  • TypeScript
  • React
  • Vite
Project notes
Why it matters

The browser-native Monaco playground and Node CLI share the same WABT-backed pipeline, with diagnostics, hovers, completions, closure conversion, high-arity and staged functions, floats, strings, sequencing/pipelines, sets, maps, runtime checks, and compiler-specialization coverage.

LiveBoard

A distributed collaborative whiteboard with realtime sync, Redis-backed fanout, durable PostgreSQL canvas state, transient drag/style previews, shared undo/redo history, live cursors, presence indicators, file management, access control, grouping, transforms, text styling, and infinite-canvas navigation.

  • TypeScript
  • React
  • Vite
  • Python
Project notes
Why it matters

FastAPI replicas coordinate through Redis Pub/Sub and shared rate-limit counters while PostgreSQL tracks revisions, history, memberships, and canvas JSON. Clients reconcile durable revisions, recover from gaps or rate limits, and keep remote cursors in sync.

  • Max
  • Max for Live
  • Ableton Live

Project notes
Why it matters

The project combines implementation and research: a real M4L audio effect plus a technical paper explaining the pleasantness-constrained DSP architecture behind it.

JaggerScript

A small typed scripting language with classes, constructors, scoped member access, control flow, object allocation, and a browser-runnable interpreter.

  • JaggerScript
  • TypeScript
  • React
  • Vite
Project notes
Why it matters

This is one of the clearest examples of how I like to work: own the grammar, compiler normalization, heap-backed runtime, Monaco diagnostics, syntax highlighting, examples, and playground interface around it.

AIXC Compressor

A deterministic predictor-based text compression format with packed hit/miss streams, residual coding, manifest hashing, and multiple predictor backends.

  • C
  • Python
  • Native C extension
  • C hot paths
Project notes
Why it matters

It explores how much archive size can move when encoder and decoder share a predictor contract, with a reference codec, CLI, tests, benchmarks, and a local workbench.

Genetic Algorithms in TypeScript

An interactive simulation where a genetic algorithm learns the launch velocity needed to hit a target under changing gravity, wind, mutation, and population settings.

  • TypeScript
  • React
  • Vite
  • Matter.js
Project notes
Why it matters

Change the environment, drag the target, rerun the population, and watch the algorithm adapt in real time through best-path traces, ghost trajectories, hit-rate metrics, and generation-by-generation feedback.

05 — About

Curious by default.
Practical on purpose.

I’m a senior full-stack engineer who likes the seams between disciplines: where product meets architecture, where a developer tool becomes a user experience, and where a complicated system can become a clear one.

Outside of work I build programming languages, renderers, games, simulations, and small experiments that teach me something new.
