Plutonus

Work A living body of work

Work 01 / Overview

Client work, products, prototypes and research

Different work.
Different weight.

Client delivery, active products, open-source experiments, proposal work and research all belong here. Each is presented for what it is, what exists now and why it matters.

Featured work 02 / Delivered + active

Two projects lead for different reasons.

One is shipped client work. The other is an active product with substantial systems depth.

Paid client work Shipped

Dobrareklama.rs / NM Produkcija

A distinctive identity and content experience the client can continue to manage.

Plutonus connected services, portfolio work, articles, audio and media into one delivered site, with a non-technical content workflow behind it.

What it proves Real external-client delivery with a live result and a client-manageable content and media workflow.

Active product Currently building

Runrail

An active product spanning backend execution, persistent state, operational controls and distinct user and public surfaces.

The work extends beyond interfaces into a product with meaningful lifecycle complexity.

Selected work 03 / Implemented + proposed

Built beyond the idea stage.

An open-source tool and a proposal prototype, each presented for what it is.

01

Developer tool Open source

LLMfuzz

A public, open-source developer-tool experiment built beyond the idea stage: campaign execution, mutation, evaluation, deduplicating triage and inspectable artifacts in a packaged command-line structure.

It is implemented and public; its future direction remains under exploration.

02

Proposal prototype Real sales opportunity

Garden Resort Menu

A functional multilingual hospitality-menu prototype, including a public menu and a focused admin workflow for price, availability and visibility changes.

A functional proposal prototype developed for a real sales opportunity; it did not become a paid or deployed client project.

Research systems 04 / Selected R&D

Questions pursued through working systems.

Both became working systems. RunMirror is now dormant, while SEF Preflight is archived.

Dormant R&D Not abandoned

RunMirror

Controlled AI-assisted execution with explicit state, human approval boundaries, atomic effects and adversarial testing.

Archived experiment Commercially unvalidated

SEF Preflight

A substantial Serbian e-invoice rules and validation system with versioned rules, canonical reports and regression evidence.

Inside the studio 05 / Supporting infrastructure

One operating environment, built around the outcomes

The studio builds some of its own tools.

When an existing workflow becomes a constraint, Plutonus may build the tool it needs. Current examples include local-media-tooling for creative production, review-diff for focused review of AI-assisted changes, and lab-mcp for giving AI controlled access to relevant development context.

These tools support production, review and human oversight while the outcome remains more important than the toolchain.

A defined build, an early idea or a problem without an obvious answer can all be useful starting points.
