United States, 2019–2023

C1 English and life in the United States

From 2019 to 2023, I lived in the United States and completed English as a Second Language (ESL) at City College of San Francisco. I also visited Facebook headquarters (now Meta) and Amazon's campus, with no professional role at either company.

Year
2020 (one of the visits)

In 2020, I visited Facebook headquarters (now Meta) in Menlo Park, California. The photos from that visit show the sign with the like symbol and the name Hacker Way, the cloud installation with the Instagram logo, and a pixel-mosaic panel of the like symbol.

I also visited the campus on another, undated occasion; the last two photos are from that visit, at the cloud installation and beside the Instagram logo sculpture. Both times I went as a visitor, with no professional role at the company.

Short clips from the campus visits

The clips have no sound and load only when you press play. Each one has a text description.

  • Lobby with the Instagram logo

    Silent clip, 7 seconds: the camera shows the Instagram logo in purple neon on a white wall, then pans across the lobby to video screens and a “Good morning” sign. The lower part of the frame, where people sit at the reception desk, is blurred. A location sticker on the image reads “Instagram HQ.”

  • Architectural scale model

    Silent clip, 15 seconds: the camera moves along a large white architectural model with miniature floors, stairs, and trees. People appear only in the distance, with no identifiable faces. A location sticker on the image reads “Facebook HQ.”

In Seattle, Washington, I went to Amazon's headquarters campus, home of The Spheres. The photo shows the glass domes at night.

Before and after the United States

Before the US, I worked with sales data and with compensation and personnel budgeting (2014–2019). After returning, I completed an MBA in Digital Media, Performance & Analytics at UNINASSAU and the Full Stack AI Programming course at Infinity School, and moved into data and Business Intelligence work in the public sector. I am now studying Computer Science.

I work in English at C1 level and maintain this portfolio in Portuguese and English. The technical proof is in the projects, not in these photos.
