I'm a Senior Frontend / Product Engineer with 10+ years of experience building complex web products, developer tools, APIs, applied-AI systems, compilers, and games. I work primarily in React and TypeScript, with enough backend, infrastructure, ML, and systems depth to own a product all the way to production.

I'm currently a fractional Lead Product Engineer, Applied AI at RetroDiffusion. Previously, I built product and platform systems at Kueski and Globant.

I'm based in Mexico and exploring remote Senior Frontend, Senior Product Engineer, and frontend-dominant full-stack roles.

• Product engineering: RetroDiffusion — a production AI pixel-art platform where I lead hands-on work across the React/FastAPI product, public API, inference and editing systems, developer tooling, and infrastructure supporting more than 150,000 registered users.
• Compilers and systems: GB Recompiled — a Game Boy and Game Boy Color static recompiler with portable C output, an SDL2 runtime, native extension APIs, validation tooling, and cross-platform releases.
• Creative tooling: Pixel VFX Studio / PVFX Foundry — a deterministic procedural pixel-VFX authoring system whose public pack ships 19 engine-ready effects.
• Applied AI: Pixel Art XL — a widely used public SDXL adapter for grid-aligned pixel-art generation.

• RetroDiffusion — React/TypeScript product architecture, FastAPI services, public and enterprise APIs, billing, generation and editing workflows, CI/CD, production operations, and serverless inference.
• Pixel Art Fixer — A browser and API workflow for turning off-grid generated imagery into editable pixel art. My work spans the product integration, Rust/WebAssembly processing, neural inference, and production delivery path.
• Pixel Art XL — Public model weights and inference guidance for reusable pixel-art generation across local tools and hosted applications.
• ACE Lab — A local-first React/FastAPI control room for datasets, training, evaluation, and inference across image and music models, with local GPU workers plus RunPod and Modal orchestration. Private development repository; public version pending.
• ACE Lab RunPod Worker — The public serverless worker/deployment boundary for ACE Lab training jobs.
• HyperTrainer worker — A RunPod worker for dataset-driven FLUX LoRA training, artifact storage, and webhook-based job completion.
• img2tiles — An AUTOMATIC1111 extension that decomposes an image into overlapping regions and regenerates them as a coherent diffusion-made tile composition.
• Antares Toolbox — A collection of small AI-development and workflow utilities.

• GB Recompiled — Static analysis and recompilation of LR35902 programs into reviewable C, backed by shared runtime devices, interpreter fallback, differential testing, deterministic captures, and native extension points.
• Crystal Recompiled — A ROM-free source alpha built on GB Recompiled with semantic game-state views, transactional native tools, deterministic data mods, and controller-first Challenge Mode.
• CHIP-8 Recompiled — The smaller C/C++ static-recompilation toolchain that preceded GB Recompiled, with native executables, a multi-ROM launcher, debugging tools, and broad compatibility testing.
• Pokémon Platinum Portable — Experimental SDL3 portability work built on the public Pokémon Platinum decompilation project. It remains source-only and contains no ROM.
• Sideband — An active TypeScript prototype for a controller-summoned Windows companion to Moonlight sessions, built around a resident runtime, manifest-driven plugins, and durable diagnostics.
• Phobos ROM Manager — A React Native handheld app plus Electron desktop companion for library management, LAN pairing, background queues, and off-device native-port builds. Private prototype; public architecture write-up pending.
• Sheaf — A quiet, e-ink-first Android reader for collaborative-fiction archives, with branch-selected offline libraries, change tracking, search, bookmarks, resumable downloads, and source-aware licensing. Private 1.0 repository; public release pending.

• Junkyard Garden — A gamepad-first Godot arena-survival roguelite with 20-wave runs, ten characters, build crafting, finite profile goals, broad data-driven content, and Web, desktop, and Android builds.
• Tiny Frontiers — A Godot 2D sandbox about gathering, crafting, farming, exploration, automation, and combat in an expanding chunk-based world.
• REGOLITH: An Autonomous Industry — An archived, controller-first Android strategy prototype built around a deterministic simulation, autonomous industry, instrumentation, and causal reports.
• Maprunner Neo — A playable autonomous-ARPG management prototype with Runner creation, automated canvas combat, mission results, itemized loot, equipment, currencies, skill/support gems, and behavior presets. Private prototype; public demo pending.
• Exiled Loot Reborn — A Godot dungeon-crawler alpha with three classes, procedural tower runs, deep data-driven itemization, affixes, skill/support gems, passive progression, and scripted bosses. Private prototype; public alpha pending.
• Open Gathering — A headless, serializable Magic: The Gathering rules engine in TypeScript with turns, priority, the stack, state-based actions, combat, an event bus, and data-driven card logic.
• OpenWood — A BepInEx modding framework and game-data reference for Littlewood, including Harmony hooks, save helpers, runtime inspection, and a controller-accessible cheat/debug surface.

• Pixel VFX Foundry — A free pack of 19 deterministic 96×96 pixel-art effects generated from the Pixel VFX Studio source workflow for use in game engines.
• Pixel VFX Studio — A deterministic, headless-first pixel-VFX compiler and authoring system with a Rust core, CLI, desktop editor, MCP adapter, versioned project format, review bundles, Aseprite round trips, and Godot integration. Private product repository; public product/source plan pending.
• Neri SCAD Models — Parametric, support-free OpenSCAD display systems for miniatures, LEGO minifigs, and 1:64 cars.
• Hobby Tracker — A self-hosted React/Remix and SQLite collection/activity tracker designed to expand across multiple hobbies. Private MVP prototype.
• Libre BioRead — A Python CLI that applies a Bionic Reading transformation to EPUB, MOBI, and AZW3 files while preserving document structure.
• Book Companions — A collection of small, book-specific reading companions.
• Stability AI API Playground — A Streamlit environment for exploring image-generation APIs.

My public archive goes back to 2015 and includes web products, mobile apps, libraries, APIs, creative tools, and early ML experiments. A few representative threads:

• Frontend and application tooling: Helios, ngx-epsidev, ngx-dionisio, Engraving Studio, and Ionic BLE Tester
• Node.js and API infrastructure: Dionisio, Prometheus, Prometheus Mongo, and Oracle Chatbots Widget
• Creative and ML experiments: Hearthstone RNN, Book It, MU Crawler, and Stability AI API Playground
