My Story

I was born in Brazil. At seventeen, my mother and I moved to the United States.

There is a version of that sentence that sounds like the beginning of an opportunity story — the kind where someone arrives in a new country and everything unfolds according to plan. That was not my version. I came to Orlando with a set of expectations about what life in America would look like, and the first few years were a slow, sometimes painful process of dismantling those expectations and learning to build something real in the space they left behind.

I started working almost immediately. My first job was as a bellperson at the Orlando Marriott. I was eighteen. I carried bags, parked cars, opened doors, and learned what it meant to be the person who shows up, does the work, and doesn't complain. That sounds like a small thing until you've done it for a year in a language you're still thinking in second.

From the Marriott I moved through a chain of hotels — Wyndham, Baymont, Best Western near Disney Springs. Front desk. Concierge. Valet. Each role taught me something the previous one hadn't. How to read a guest's mood in three seconds. How to de-escalate a situation before it becomes one. How to work nights, weekends, and holidays without losing your sense of self. By twenty-three I was the front desk manager at the Clarion Hotel on Universal Boulevard, running a team of twenty people across housekeeping and front office operations. I was good at it. I was also deeply aware that it was not the destination.

The hospitality years

Hospitality taught me something that no bootcamp or degree ever could: how real businesses run before anyone builds them a dashboard. How revenue actually works. What happens when a system breaks at 2 AM and the person who built it is asleep. These lessons became the invisible foundation under everything I built later.

The tech thread had always been there. Back in Brazil, at fourteen, I earned a hardware technical certificate at Fatec Sebrae. I understood machines before I understood the language of the country I was living in. But technology in my early twenties was not the path of least resistance — hospitality was. So the code waited.

In 2008, I started a creative collective with friends. We made things — music, design, web experiments, whatever we could build with no money and too many ideas. That collective eventually became the seed of something more formal. In July 2014, I incorporated Absolutely Plausible as a real business entity. It started as a web development and freelance consulting practice, and it has been running ever since — over eleven years now, through every other job, every career pivot, every relocation.

In 2017, two things happened that changed the shape of my life. First, I enrolled at The Iron Yard in Orlando for back-end development. The Iron Yard was my bridge from hospitality back into engineering, and I threw myself into it completely. I became a community advocate and interpreter at the school, helping other students — especially other immigrants — navigate the program. Second, I auditioned for the Bach Festival Choir of Winter Park and was accepted as a First Bass. The Bach Festival Society has existed since 1935. The Wall Street Journal once described it as one of the finest organizations of its kind in America. I have sung with them for over eight years now, performing Bach, Verdi, Mozart, Brahms, Rossini — the full canon of Western choral masterworks — alongside a 150-voice choir and full orchestra, with PBS appearances and international tours. Monday evenings, mid-August through May. That schedule is non-negotiable, and I have built my life around it.

The following year I enrolled in the culinary arts certificate program at Pathlight Kitchen, a job-training program run by Pathlight HOME, a social services organization supporting adults with intellectual and developmental disabilities. I completed the certificate and simultaneously volunteered as a teacher assistant. It was one community, two commitments. The culinary training was real — knife skills, kitchen management, food safety — but the deeper education was in patience, in meeting people where they are, in understanding that not everyone starts from the same place.

Then came the pandemic, and with it a full reset. I worked IT support at a law office. I tended bar seasonally. I volunteered at Back to Nature Wildlife Refuge — six months of property maintenance, clinic work, rescue intake, daily animal nutrition. I served a ten-day silent meditation course at the Southeast Vipassana Center as a kitchen volunteer, where I managed the daily sorting of all kitchen waste into recyclables, compostable material, and haul-out. The zero-waste principle I carry now is not something I read about. It is something I practiced in silence, with my hands, for ten days.

The zero-waste thread

Wildlife refuge. Composting at a meditation retreat. Culinary training at a social enterprise. These all came before the business plan. The sustainability values in this company are not marketing — they are autobiography.

Somewhere in the middle of all of this, I started making punk music. Robot Fantome is my music project — French for robot ghost. Indie, punk, rock, released through stolenghost recordings. A five-track EP that I fully own, with zero licensing costs. The music is not a side project. It is a parallel life. Bach on Monday night, punk on Saturday. That is not a contradiction. That is the most honest version of who I am.

My entry into the karting industry came in 2017, and it deepened in 2022 when I joined PCJ — Parazinho Chassis Jig as a traveling mechanic. Four years on the road. Major series, tracks coast to coast. I learned the sport from the inside — not as a spectator or a vendor, but as the person under the kart with a wrench, in the rain, at seven in the morning, making sure the chassis is right before qualifying. The Brazilian karting community is the dominant force in American karting. I speak their language natively. I worked alongside them every weekend for four years. No competitor in the tech space has that access without a translator.

Somewhere in the middle of that, I built hackFatura. In a single AI-powered session, I created a zero-cost field management application — race entry tracking, mechanic assignment, event data. It was the first real product to come out of Absolutely Plausible, and it proved something I had suspected for a long time: that the combination of things I know — hospitality operations, motorsports logistics, software engineering, AI tooling, trilingual communication — is not a scattered resume. It is a stack. And no one else has this particular stack.

In early 2026, the PCJ chapter closed. The next one opened almost immediately: a karting team owner in Orlando saw hackFatura and wanted Absolutely Plausible to take charge of his whole operation — store, warehouse, shop, school. The shape of the business shifted. The mechanic became the operations partner. Same access to the community, different role.

That is what this business plan is. It is the document that takes twenty years of seemingly unrelated experience and shows how it all connects. The bellperson became the manager. The manager became the developer. The developer became the mechanic. The mechanic became the builder. And the builder is now the founder of something that has been running, quietly, for over a decade — waiting for the moment when all the pieces were finally in place.

This is that moment.

The Unfair Stack

No one else has this combination:

  • Karting industry insider since 2017 — nine years in the sport, including four as embedded traveling mechanic (2022–2026, PCJ). Now pivoting to operations partner work. Same community access, different role.
  • Ships real software — built hackFatura (zero-cost field app) in a single session with AI
  • AI-native — runs own agent infrastructure, understands automation at a systems level
  • Trilingual: English, Portuguese, Spanish — the Brazilian karting community is the dominant force in US karting. Pitches, sells, supports, and builds relationships in Portuguese natively. No competitor has this access without a translator.
  • 20 years of customer-facing roles — hospitality management, multilingual concierge, healthcare marketing, legal IT. Knows how real businesses work before they have tech.
  • Two distinct music careers — Robot Fantôme (punk/indie/rock, 10+ years) AND Bach Festival Choir (classical, world-class, audition-only, 8+ years). Both real. Both ongoing.
  • Open-source and sustainability — not a brand value, a lived practice. Wildlife refuge volunteer, Vipassana kitchen waste management, culinary training at a social enterprise. This predates the business plan.

Why this matters

The unfair stack is not a marketing concept. It is the reason Absolutely Plausible can operate in spaces where traditional agencies cannot. Every line above represents years of accumulated context that cannot be hired for or replicated quickly. The stack is the moat.

Southeast Vipassana Center, Dhamma Patapa — served a 10-day silent meditation course as kitchen volunteer. Led daily task flow, oversaw proper sorting of all kitchen waste: recyclables, biodegradable compost, and hauling to designated facilities.

Absolutely Plausible

The business entity. The engine behind everything commercial.

  • Creative collective roots: 2008
  • Formally incorporated: July 2014
  • Running: 11+ years
  • Dream Team formalized: May 2026 — Luiz (founder + main ops, Orlando), Bebeco / Dad (operations oversight + advisor, Brazil), Samuel / brother (future contributor, Brazil). See Team.

Absolutely Plausible is the company Luiz Wagner Mestrinho founded to house his professional work — web development, AI tooling, operations partnerships, and digital products. It is not a music label. It is not a creative alias. It is the business. Family-anchored from May 2026 onward.

  • Domains: robotfantome.com · ops.absolutelyplausible.com · robotfantome.crypto (Unstoppable Domains — Web3)
  • Focus: Web development, AI tooling, freelance consulting, digital products
  • First product: hackFatura — a PCJ-era field management system and proof-of-concept; retired as an active project and superseded by AP Ops
  • Aesthetic: Clean, minimal, editorial. White space is a feature. See Brand.

Absolutely Plausible vs Robot Fantome

Absolutely Plausible is the business entity — consulting, development, products, revenue. Robot Fantome is the music project — punk, indie, rock, creative output. The two are related (Absolutely Plausible owns the infrastructure, Robot Fantome provides original content and brand identity) but they are not the same thing. When a client hires the company, they hire Absolutely Plausible. When someone listens to the EP, they are listening to Robot Fantome.

Robot Fantome

The punk music project. French for robot ghost.

Genre: Indie / Punk / Rock — released via stolenghost recordings.

Robot Fantome is Luiz's personal creative outlet. It is not the business. It is not the consulting practice. It is the music — raw, self-produced, entirely owned. The EP exists as both art and asset: zero licensing costs mean every track can be used across Absolutely Plausible's content, client demos, and live presentations without clearing rights or paying royalties.

Bach Festival Choir

Member since August 2017 — the Bach Festival Society of Winter Park.

  • Voice part: First Bass
  • Audition-only, 150-voice choir + full orchestra. Founded 1935.
  • PBS appearances. Tours with the London Symphony Orchestra. Italian tour 2025.
  • Repertoire: Bach, Verdi, Mozart, Brahms, Rossini — the canon of choral masterworks
  • Monday evening rehearsals, mid-August through May — hard schedule constraint
  • ~150 musicians in Central Florida = warm professional network
  • Also serves as Usher (Apr 2020–present) — front-of-house, guest experience at concerts

The contrast between choir and punk is not a contradiction — it is the most honest version of who Luiz is. Bach on Monday, punk on Saturday. Discipline and freedom. Structure and chaos. Both real. Both ongoing. Both non-negotiable.

The Ghost in the Machine

The identity thread that runs through everything: a force that moves fast, fixes things, doesn't leave a trace of waste, and operates in the background until something needs doing.

The bellperson who became the manager. The manager who became the developer. The developer who became the mechanic. The mechanic who became the builder. And the builder who has been running a company, quietly, for over a decade — waiting for the moment when all the pieces were finally in place.

Open Source. Cyberpunk. Revolutionary.
