Alura courses: HTTP and secure development for 32k+ students

Sun, 15 Oct 2023 00:00:00 +0000

What it is

Three online developer courses I authored for Alura, Brazil’s largest developer-education platform. Together they reached 32k+ students with an average rating of 9.2/10. Two of them are part of Alura’s DevOps Security track.

What I built

24 hours of structured content total, in Portuguese, all video-led with hands-on exercises:

HTTP: entendendo a web por baixo dos panos (10 h) — HTTP/HTTPS fundamentals, HTTP/2 and HTTP/3, URLs, headers, request/response. The “how does the web actually work” course.
Desenvolvimento Seguro: lidando com erros e logs em uma aplicação (6 h) — error-safe coding, log hygiene, cryptographic integrity for log records, Elasticsearch + Kibana for analysis. Applied to Node.js / TypeScript APIs.
Desenvolvimento seguro com DAST e SCA: protegendo as dependências e a aplicação em execução (8 h) — Software Composition Analysis and Dynamic Application Security Testing for Node.js apps, integrated into CI pipelines with Dependency Track, Nuclei, and Snyk.

For each course I owned the full course-authoring pipeline: instructional design, scripting, video recording and editing, exercise design, and the supporting code, examples, and quizzes.

Challenges

Translating production-grade security practice into an asynchronous, Portuguese-language course for working developers
Deep technical material (HTTP/3, DAST, SCA) in 6–10 h chunks needs aggressive pruning and careful sequencing
Asynchronous video has no Q&A safety net — every example has to land cleanly the first time
Shipping a steady cadence of recorded content while working part-time and remotely

Numbers

32k+ students across the three courses
9.2/10 average student rating
24 hours of content
3 courses, two of them in Alura’s DevOps Security track
Tenure: June 2022 → October 2023 (remote, part-time)

CodeIoT IOT101: a free IoT MOOC for 100k+ Brazilian students

Fri, 15 Jan 2021 00:00:00 +0000

What it is

CodeIoT is a free Brazilian online learning platform for Internet of Things education — sponsored by Samsung, developed by LSI-TEC, and running on OpenEdX. The catalog covers 6 courses from introductory IoT through electronics, programming, mobile apps, and connected devices.

I co-authored IOT101 — Introdução à Internet das Coisas (“Introduction to the Internet of Things”), the platform’s gateway course, alongside Laisa Costa de Biase and Ana Grasielle Dionisio Correa.

What I built

Twelve hours of structured content that takes a learner from zero to a working understanding of what IoT is and what they can do with it.

Co-designed and co-authored with Laisa and Ana Grasi:

Curriculum and learning sequence — what does a beginner need to understand, and in what order
Video lectures and on-camera presentation — including the intro video above
Written modules, exercises, and supporting materials
The narrative arc: what is the internet → what is IoT → how do they meet → what can you build → where is the field going

This was an end-to-end course-authoring exercise: instructional design, scripting, on-camera video, exercise design, and the discipline to ship coherent self-paced content for a national audience.

Challenges

The audience ranged from absolute beginners to high-school students with no programming background — depth and accessibility had to coexist
Producing video + writing + exercises in Portuguese for a national audience meant production discipline beyond just knowing the material
Asynchronous self-paced learning needs more pedagogical design than a live class — every concept has to land on the first try, with no Q&A safety net
Coordinating three co-authors so the course had one coherent voice

Numbers

100k+ students reached
12 hours of structured content
3 co-authors: Laisa Costa de Biase, Ana Grasielle Dionisio Correa, and me
3 languages — Portuguese original, with full English and Spanish translation of all written content and subtitles (audio stays in Portuguese)
