About
Hi, I'm Nico.
I build at the intersection of systems, design, and story. Over the last two and a half years, that has meant websites, interfaces, automations, funnels, demos, videos, and client systems for real businesses.
What I bring is a visual sense, a systems mind, and the patience to shape an idea until it feels clear. I first learned that through video editing. The medium has expanded, but the work is the same: understand what matters, shape it with diligence, and build something people can love and trust.
Things I've Built Recently:
Agency · 2023 to now
Ventari. A studio where I built the digital layer around founder-led businesses.
Video edits
Co-ran a 12-client studio while finishing Berkeley, building websites, funnels, payments, email systems, e-commerce, video, and handoff for real clients.
Why it belongs here
I joined as one of the founding contributors while building deeper experience in software and business. The original app was already underway; my value was stepping into the real-world layer: restaurant tools, UI decisions, bugs, releases, and creative assets.
What I owned
My main ownership was the restaurant app. I helped push it forward with AI-assisted coding, QA passes, UI polish, optimization, and the release path to Google Play and the App Store.
Across the ecosystem
I contributed to the customer, driver, and restaurant experience by helping with bugs, UI design details, strategy, and launch readiness. AI was part of the workflow throughout: coding, planning, design iteration, and review.
Marketing
I also helped edit Colibri marketing videos, including AI-assisted motion and campaign pieces. It gave me practical reps in the full startup loop: product, operations, release, and storytelling.

Product
Synchronicity
A personal journal for the small signs you notice in your life.
Overview
Synchronicity is a personal journal for the small signs you notice in your life. You log them as they happen, AI threads the patterns over time, and you can share an entry with a friend when the moment calls for it.
The story
I built this for my girlfriend as a Christmas gift. She had been keeping her synchronicities in the Notes app, and I wanted her to have something real for them. So I made it. The part that matters here: I shipped a real product, end to end, with AI in every seat of the build.
What I shipped
My idea, my design, my code. Auth flow, Firebase backend, every visual decision, prompt engineering, full implementation. Shipped on Netlify, live as a PWA, App Store next. 24 sign-ups so far. Built with Cursor, Claude Code, Codex, and Gemini orchestrated together, which is the way I work now.

AI starter kit
Lumina Agent Kit
A plain Markdown starter kit for turning a blank AI chat into a personal assistant workspace.
Lumina is meant to illuminate. I designed it to bring light into the first intimidating steps of AI: answer a guided questionnaire, get starter memory files, skills, tasks, and personal context, then bring that folder into the assistant you already use.
The deeper idea is simple: take the structure of my personal OS and make it reusable, so friends, family, clients, and curious people can start from a real shape on day one.
The engine can be Claude Code, Codex, Hermes, or whatever comes next. Lumina gives it the human context: what the person cares about, what to remember, what work is active, and where the assistant should slow down and ask.
Questionnaire
Plain questions turn a person's goals, projects, habits, and preferences into starter context.
Memory
Readable files for goals, tasks, projects, notes, and lessons.
Skills
Small reusable workflows for writing, planning, research, and handoff.
Runtime
A context folder that can travel into Claude Code, Codex, Hermes, or another engine.
