Otacilio Maia

I build software
and people.

I lead teams and build digital products connecting engineering, education, and social impact.

manifesto / 001

Every project is a technical decision that creates an impact on people.

01 / about

Technology is a
human practice.

My journey began with electronics, robotics, and embedded systems, then evolved into digital products, open-source communities, and engineering leadership.

Today, I turn complex problems into useful software — and help create environments where people can grow, too.

01

Engineering and leadership

Products, systems, and teams that treat quality as a daily practice.

02

AI applied to education

Technology with human review to expand access to education at scale.

03

Open source and community

Shared knowledge that lowers barriers and connects people.

04

Research and invention

Electronics, telemetry, and software meeting problems in the physical world.

02 / selected work

Decisions that
move something.

A small selection of work where software, education, and community meet.

01Public education · Applied AI

AprendiZAP

Engineering and generative AI supporting free educational content, with human review at the center of the process.

problem
Scale quality learning content without losing context or responsibility.
decision
Combine prompt engineering, automation, and human pedagogical review.
impact
1,428 lessons and more than 8,000 activities in the published case study.

02C++ · Arduino · Open source

Brasilino

A Brazilian Portuguese layer that makes a learner’s first steps with Arduino feel closer and more accessible.

problem
Language created an unnecessary barrier to learning programming and electronics.
decision
Translate concepts into a simple, open interface built for an educational context.
impact
A public project with a community, releases, and use across robotics and education.

03ReciHub · Hacktoberfest · Teaching

Code that creates community

Projects and gatherings that turn contribution into belonging — and documentation into an open door.

problem
Participating in technology still feels inaccessible to many people.
decision
Create curation, open projects, and environments for collective learning.
impact
Initiatives such as ReciHub and awesome-hacktoberfest connect people with real-world practices.

04Embedded systems · Automation

Telemetry and invention

Applied research in sensors, energy, data transmission, and software for observing the physical world.

problem
Reliably monitor and control distributed physical systems.
decision
Combine electronics, sensor networks, embedded systems, and visualization.
impact
Co-inventor on three published patent applications and co-author/creator of one software registration.

03 / signals of impact

Numbers need
context.

Volume without method is just noise. These milestones tell part of the story — and show where they come from.

+8Keducational activities

Generated from 1,428 lessons in a published AprendiZAP case study, with human review.

public source
3published applications

Co-inventor of telemetry, monitoring, and automation technologies.

1software registration

One of the creators of the registered software SOFIA.

04 / journey

A journey without a
straight line.

1

the start

Electronics as a language

Technical training, robotics, and embedded systems turn curiosity into prototypes.

2

then

Software as a bridge

Web, mobile, and open source take ideas beyond the workbench.

3

now

Leadership as a multiplier

Educational products and engineering teams connect technical decisions to social impact.

05 / teaching & community

Knowledge only grows
when it moves.

Classes, stages, and communities as extensions of the same practice: making technology more accessible.

07 / next commit

Have an idea that
deserves to exist?

I enjoy conversations about engineering, education, communities, and difficult problems that need clarity.
