Jonathan “Nagui” Pinetta

Product architect, technical writer, and AI systems builder.

I design documentation systems, localization workflows, AI-powered tools, and product interfaces that turn complex operations into usable systems.

01 / Selected work

Featured projects

Eight systems built end to end — from problem framing and architecture to working product. Execution platforms, localization engines, evaluation tooling, and operator consoles.

Execution System

Dark Factory

AI product engineering platform — from design interview to spec, wireframe, pipeline run, and published artifact.

Problem
AI-assisted product work fragments across chat, docs, and tickets — leaving specs untracked, runs unreviewable, and decisions undiffable.
Built
A full-stack platform covering the design-to-delivery loop: interview sessions, spec synthesis, wireframes, pipeline runs, quality scoring, and artifact publishing — all anchored to run IDs.
Why it matters
Treats every product decision as a traceable, replayable run — not a chat log. Specs diff. Runs compare. Artifacts ship.
  • Multi-agent
  • Spec-first
  • Full-stack

Agent Governance

AEO Kit + AEO Console

Schema, CLI, and console tooling for governing agent-facing interfaces.

Problem
Agent tools and policies drift when teams define them through scattered prompts and config files.
Built
A TypeScript monorepo with schema, core build/audit/policy engine, CLI, and OpenAI/MCP-oriented emitters, paired with a local SvelteKit/Tauri console using SQLite and Drizzle.
Why it matters
Treats agent tools as managed interfaces that can be validated, tested, and operated locally.
  • Schema
  • CLI
  • Local-first

Platform Prototype

NexusAI Platform

High-fidelity AI operations console prototype with local-first data and orchestration UI.

Problem
AI platform concepts need credible IA and operator workflows before full backend investment.
Built
A SvelteKit prototype with dashboard, logs, models, jobs, chat, workbench, orchestrator canvas, sql.js client-side SQLite, optional Supabase sync, and test coverage.
Why it matters
Demonstrates platform thinking, operator UX, and a mock-to-cloud migration path without pretending to be a production backend.
  • Prototype
  • Operator UX
  • sql.js

Localization Engine

Omniglot

Localization systems for structured translation workflows, file ingestion, QA, TM, and glossary support.

Problem
Localization workflows break down around messy formats, context loss, inconsistent QA, and spreadsheet-based handoffs.
Built
Omniglot Wrapper for file-heavy import/export and validation workflows, plus Omniglot Next Gen as a spec-driven platform for projects, keys, documents, TM/glossary, QA, and guarded AI assistance.
Why it matters
Connects localization expertise with AI-assisted product engineering and operational workflow design.
  • Localization
  • Spec-driven
  • ETL
Case study — soon
Local MLOps

TuneKit

Local fine-tuning platform — training runs, adapter registry, eval suites, and efficiency analytics in one operator UI.

Problem
Local fine-tuning is scattered across scripts, terminal logs, and ad-hoc notebooks — making runs hard to track, compare, or hand off.
Built
A full-stack MLOps UI with starter kits, dataset recipes, training run history, live metrics, a versioned adapter registry, eval suites, and a chat lab for model validation.
Why it matters
Brings production MLOps structure to local LLM experimentation — every run is reproducible, every adapter is versioned, every result is inspectable.

Signal Intelligence

Noise Distiller

Feed aggregation and intelligence platform — correlated event clustering, AI briefings, and synthesis pipeline for signal-heavy research.

Problem
Research and signal monitoring is fragmented across dozens of feeds, with no layer to correlate events, surface patterns, or generate structured briefings.
Built
A full-stack intelligence platform with multi-source feed ingestion, correlated cluster analysis, AI-generated briefings, a synthesis pipeline for artifact generation, and advisor and monitor workflows.
Why it matters
Turns a firehose of sources into structured intelligence — correlated clusters, briefings with source lineage, and synthesis artifacts that are replayable and comparable.
  • Feed aggregation
  • Intelligence
  • Synthesis

LLM Evaluation

Benchy

LLM code benchmark platform — real production corpora, multi-task evaluation, and per-model analysis with recall, hallucination, and decay metrics.

Problem
LLM benchmarks rely on synthetic datasets that don't reflect how models perform on real, dense production code — making model selection for engineering tasks largely guesswork.
Built
A benchmark runner and analysis platform using real production code corpora to evaluate models on recall-verbatim, compose, simplify, docgen, and repair tasks — with leaderboards, per-function drill-down, hallucination tracking, and decay curve analysis.
Why it matters
Grounds model evaluation in real-world code tasks. The analysis layer surfaces not just accuracy but hallucination rate, recall vs position, and per-function failure modes.

  • Code corpora
  • Multi-model

Developer Tool

Night Loop

Spec-first project OS for agentic development — task lifecycle, work sessions, operational insight, and delivery metrics in a synthwave TUI.

Problem
Agentic development workflows fragment across terminals, docs, and chat — there's no unified surface for tracking tasks, sessions, specs, and risk signals in one place.
Built
A spec-first project OS with a synthwave TUI — tasks, work sessions, specs, context, insight, delivery metrics, review intelligence, and operational risk scoring — all local, filesystem-backed.
Why it matters
Treats the agentic dev loop as infrastructure: every session is logged, every task is traceable, and the TUI gives real-time operational health without leaving the terminal.

Recurring patterns

Architecture decisions that repeat across these systems.

  • Spec-First Development

    Specs and plans drive work: Dark Factory runs, AEO interface artifacts, and Omniglot Next Gen’s authoritative specs tree.

    Dark Factory · Omniglot · AEO Kit + AEO Console

  • Model-Agnostic Architecture

    Dry runs, local LLMs, and swappable provider options where implemented — without hard-binding the whole stack to one vendor.

    Dark Factory · NexusAI Platform · TuneKit

  • Local-First + Cloud Hybrid

    Workstations and SQLite-first paths, with optional cloud sync or hosting where the repo actually wires it.

    TuneKit · NexusAI Platform · AEO Kit + AEO Console

  • Human-in-the-Loop Validation

    Review-oriented flows: Omniglot QA in context, segment review, and SME-style checks.

    Omniglot

  • Deterministic Workflows

    Dry mode, CLI checks, and artifact-oriented pipelines so outcomes are inspectable instead of one-off chat.

    Dark Factory · AEO Kit + AEO Console

  • UI as Operational Surface

    Consoles and prototypes built as operator surfaces — dashboards, jobs, tuning, settings — not slide-only narratives.

02 / Capabilities

What I build with

  • AI product design

    Designing AI features around real workflows — agents, copilots, and pipelines that earn their place in the product.

  • Technical documentation systems

    Docs as infrastructure: information architecture, content pipelines, and knowledge bases that stay accurate as the product moves.

  • UX writing & microcopy

    Interface language that carries the system model — states, errors, empty screens, and the words between clicks.

  • Localization architecture

    Translation workflows, glossary systems, and batch pipelines that scale content across locales without losing control.

  • SvelteKit product prototyping

    From concept to working product surface fast — typed, componentized, and ready to put in front of real users.

  • Workflow automation

    Bots, schedulers, and integrations that remove the manual loop between tools people already use.

  • Agent & RAG system design

    Retrieval, grounding, and agent orchestration designed for traceability — answers you can audit, not just generate.

03 / Philosophy

How I work

  1. Systems before screens.

  2. Documentation is product infrastructure.

  3. AI should reduce operational drag, not add abstraction.

  4. Interfaces should expose truth, not decorative complexity.

04 / About

Behind the systems

I work across product, documentation, localization, and AI tooling. My focus is turning messy workflows into structured systems: knowledge bases, translation pipelines, automation tools, agent interfaces, and developer-facing products.
