about

I build platforms that make engineers faster.

I’m a hands-on Tech Team Lead and Advisory-level Software Engineer with 13+ years of experience. I connect systems, automate the boring parts of engineering work, and build AI-driven tools that live inside the workflows engineers already use, so teams move faster.

I still write code every day while leading the technical side of the team: architecture, quality and delivery.

I grew up in Itu and have lived in Campinas for years, both in the São Paulo countryside. I chose programming for a simple reason: I like building things.

That’s Paçoca. She’s not impressed.

work

I turn wasted hours into automation.

At Motorola Mobility — a global company with teams across China, India, Brazil and the USA — I build internal platforms and AI tooling for engineers, in Python and Java.

Somewhere, it’s always working hours

Built with React, TypeScript and a hand-written physics engine

Colophon

Each note below is an ADR (Architecture Decision Record): a short record of one technical decision and why it was made. I use them at work; here they explain the choices behind this page.

  1. ADR-001

    Scroll is the conductor

    The swarm gathers on whatever sits in the middle of the screen, going down or back up. The page scrolls normally; the fireflies follow it, never the other way round.

  2. ADR-002

    A face made of light

    The portrait was traced from a photo at build time into 700 points (360 on phones). A faint, small copy of the photo sits behind them and warms up as they arrive.

  3. ADR-003

    Hand-written physics

    No animation library. Every motion is a spring, a damper or a force, in under 900 lines of TypeScript that are unit-tested like any other code.

  4. ADR-004

    Fixed timestep

    Physics advances in steps of exactly 1/120 s, so the swarm moves the same way at 60 Hz and at 144 Hz, and the tests are deterministic.

  5. ADR-005

    Neighbours without the O(n²)

    Fireflies avoid each other, so every step needs each one’s neighbours. A uniform grid, rebuilt every step with a counting sort, makes that O(n) instead of O(n²).

  6. ADR-006

    Wind that never piles up

    Loose fireflies follow the curl of a simplex-noise field. A curl is divergence-free, so they drift like smoke in still air: they swirl, but never clump into sinks.

  7. ADR-007

    Fireflies that flash like fireflies

    Each one is an integrate-and-fire oscillator. Loose, they blink out of phase; in formation, they nudge each other into one soft pulse, as Photinus fireflies do.

  8. ADR-008

    The page tells the fireflies where the words are

    To form a word, the engine draws it offscreen with its real computed font, one rectangle per word, then samples the pixels. Line wrapping on any screen is respected, and no coordinates are hard-coded.

  9. ADR-009

    Engine outside React

    React renders the content. The engine writes to the canvas and to one CSS variable per element, so nothing re-renders while things move.

  10. ADR-010

    Content is never hidden

    Unlit text is dim but passes WCAG AA. Light is emphasis, not a gate. The page is prerendered HTML and reads fine without JavaScript.

  11. ADR-011

    A missing translation fails the build

    All copy lives in one typed Content interface. English and Portuguese must both satisfy it, so a missing string is a compile error, not a blank spot in production.

  12. ADR-012

    Performance budget

    60 fps. Up to 260 fireflies are awake at once; the rest sleep until the portrait needs them. If frames run long, a quarter of the swarm is dropped, down to a floor, and it never grows back during that visit. The loop pauses when the tab is hidden. With reduced motion, everything starts lit and still.
