Hi, I’m
Adriel Figueiredo.

I build applications and systems with the whole path in mind: from the experience people have to the service that keeps it running.

01 / SELECTED WORK

Projects with open code.

A selection of what I’ve published. The repositories show the code and where each project stands.

DESKTOP APPLICATION01

BOBBY Bilheteria

An Electron ticketing project. The repository includes the interface, main process and installer configuration.

BOT & INTEGRATION02

PCM-Verify

A Discord verification bot written in TypeScript with Discord.js and Express. The README documents requirements and run commands.

02 / TOOLS & PRACTICE

I like to understand the whole system.

The stack changes with the problem. These are tools I work with and subjects I keep studying.

I start with what the product needs to do; then I choose its language, structure, storage and delivery.

THINK → BUILD → REFINE
01

Languages & interface

Responsive interfaces and web applications.

02

Backend & integrations

APIs, services, bots and real-time communication.

On my radar

Technologies I’m exploring, without presenting them as established specialisms.

03 / A LITTLE ABOUT ME

Curiosity across the layers.

I’m a software developer. I enjoy building the product, but I also want to know what happens after it leaves my machine.

That interest takes me into backend, networks, operating systems, infrastructure and security. My technical education in electronics and studies in computing and networking inform this broader view. I don’t claim to know everything: I try to ask good questions, test assumptions and write code someone else can maintain.
