Engineering ideas
into working things.
I'm João, a software developer and Computer Engineering student at UFPA. I connect code, data and devices to turn questions into projects you can explore.
DEVICES → DATA → EXPERIENCES
01 / SELECTED WORK
Ideas in working order.
Nine views into what I like to build. Explore the context, choices and code behind each project.
Product · Cross-platform
DMóvel
An application in the DMóvel ecosystem with web access and mobile distributions, developed in the academic context of LAPSHub.
Algorithms · Visualization
Evolutionary Lab
A browser-based lab comparing genetic algorithms, particle swarm optimization and differential evolution on benchmark functions.
Published · Data visualization
Cartilha Dash
A practical guide to building interactive dashboards with Python, Dash and Plotly, with learning material available in the browser.
Published · Interactive presentation
DMóvel · SITEC 2026
DMóvel presentation for SITEC UFPA 2026, bringing together video, project context and QR-code access to experimentation.
Public code · Automation
SIGAA UFPA MCP
An MCP server for automating access to UFPA's SIGAA, exploring browser integration and authentication workflows.
Public code · Developer tools
Varedura
Tools for Docker cleanup, network monitoring and MCP integration. The repository documents development with GitHub Copilot CLI.
Public code · Backend
Klique API
The Python backend for Klique. Source code and development history are available on GitHub.
Contribution · Federated learning
Federated Learning
Contribution to a federated-learning project repository with notebook experiments. Participation can be checked in the public history.
02 / PLAYGROUND
Less presentation. More experimentation.
Move the controls. Watch the result. That's how I like to learn and build.
EXPERIMENT 001
From noise to signal
A small processing experiment: adjust the noise and see how a moving average smooths a synthetic signal.
Local educational simulation. No sensors are used; these are not AetherSense measurements.

Keep exploring
Compare GA, PSO and differential evolution in a complete lab, with 3D surfaces and adjustable parameters.
03 / THE PERSON BEHIND THE CODE
It starts with curiosity.
I enjoy understanding the whole system: from acquiring a signal to the API that processes it and the interface that makes the result useful. My experience comes from academic and personal projects, with an emphasis on learning, documentation and verifiable work.
Computer Engineering · UFPA
Bachelor's degree in progress · expected graduation in 2026. Advanced English, as stated in my résumé.
2022 — present
Software & interfaces
Academic and personal projects involving web development, APIs and cross-platform applications.
2023 — present
Devices & signals
Exploring ESP32, IoT and signal processing. AetherSense is my undergraduate thesis project in development.
2024 — present
Integrations & automation
Python, service integrations and tools that reduce manual work.
From devices to experiences: select a skill to discover related projects.
04 / OUR NEXT CONVERSATION
Let's build what comes next.
I'm looking for a software internship where I can contribute, learn from a team and work on real problems. I'm also happy to exchange ideas about the projects.
