Mark GusteticI build thoughtful software with AI.

This is a record of the products, systems, images, and creative experiments I have made—along with some of the thinking behind them.

PX-01 / MACOS PRODUCT

Open source · v1.1

Pomodoro Count

A native macOS menu bar app for counting focus sessions completed on a physical timer, through a global shortcut, or with its built-in timer. Categories, daily goals, streaks, a year heatmap, and CSV export turn a tiny tally into a private focus record.

03Artifacts

A closer look at the work.

A few notes on the problems, choices, and results behind past builds.

Open Artifacts

PF-01 / AI EXPERIENCE

Operator Console for AI Workflows

An interface for running retrieval, tool calls, and human review checkpoints. The hard part was making something probabilistic feel predictable to the person operating it.

OutcomeOperators finished tasks faster and made fewer errors once every state transition was explicit.

PF-02 / FRONTEND SYSTEM

Composable Interface Platform

A component architecture for AI-facing UI surfaces. Streaming, accessibility, and interaction details get solved once instead of once per feature.

OutcomeNew features shipped in days instead of weeks, and the UI stayed consistent.

PF-03 / BACKEND INFRASTRUCTURE

Reliable Service Mesh for AI Products

An event-driven backend with queues, idempotent handlers, and observability built in from the start. Model workloads are spiky, so the plumbing has to absorb that.

OutcomeRuntime behavior stayed steady under bursty model and request loads.

04Resonance

Pictures, sound, and experiments.

A place for ideas that do not fit neatly into an app: music, images, generative work, and whatever else I am exploring.

RS-01 / MUSIC SYSTEM

Neural Night Drive

A cinematic electronic track set shaped from modular synth layers, pulse-sequenced bass, and reactive visual cues.

Music Production

2026

RS-02 / SOUND DESIGN

Signal Garden

Ambient textures and glitch percussion generated from processed machine hum, room tone, and resampled interface sounds.

Sound Design

2025

RS-03 / DIGITAL ART

Voltage Bloom

A procedural visual series built from layered noise fields, geometric masks, and palette transitions tuned to music timing.

Generative Visuals

2026

05Technical

How I made this site.

Code, generated imagery, and a little motion—all made to support the work instead of getting in its way.

Open Technical

World Layer

Generative video pipeline

Midjourney stills animated by Kling and Seedance, scroll-scrubbed as a fixed world-layer with keyframe-dense encodes and static fallbacks.

  • Midjourney
  • Higgsfield
  • FFmpeg

Interaction Layer

Deterministic motion

GSAP ScrollTrigger choreography, rAF-lerped scrub timelines, and full reduced-motion fallback paths.

  • GSAP
  • Astro transitions
  • A11y fallbacks

Runtime Layer

The dependable core

Typed contracts across interface state, tool boundaries, queues, and observability. This is the part that just has to keep working.

  • TypeScript
  • Node.js
  • PostgreSQL

06Origin

The person behind the work.

A little about how I think, what I am drawn to, and how to get in touch.

Background

Programmer working across product, frontend, and backend

Focus

Building with AI, from useful tools to the systems around them

Operating Mode

Make things, pay attention, write down what I learn
