My Journey in Software Development
I've been a software developer for over 20 years, starting with languages like BASIC (on MSX and Apple II), Pascal and Delphi.
My journey has taken me through a variety of languages, including TCL, Java, C, and ultimately, Python – my primary language today.
It's an amazing tool, but I also leverage other languages as needed, such as Shell, Golang, and Java.
When it comes to databases, I have a strong foundation in SQL and experience with various RDBMS systems including MySQL, PostgreSQL, Oracle, and SQLite. I've also worked with NoSQL databases like MongoDB, Redis, and OpenSearch.
In the web development arena, I utilize frameworks like Django and FastAPI. I'm also currently exploring Java frameworks like SpringBoot and Quarkus. I'm well-versed in operating systems like Linux, Windows, and macOS, with Linux being my preferred choice. I frequently use Linux for system installation, deployment, configuration, firewall management, log troubleshooting, optimization, and problem-solving.
For the past several years, I've been working at GPr Sistemas as a software engineer and tech lead, developing diverse solutions using agile methodologies and DevOps philosophy and tools. My current focus is on automation tools like Ansible and Terraform, along with CI/CD tools like Jenkins and Gitlab. I hold a Cloud Practitioner certification from AWS and I am also familiar with Azure and Digital Ocean.
Currently, I'm involved in developing a system/app for log and trace analysis, leveraging Python, Django, OpenSearch, OpenTelemetry and PostgreSQL.
Below are some projects in which I participated, designing, implementing, and deploying these systems.

4G Pi Router
This is a experimental project to transform Raspberry PI 3 on a portable 4G/Wifi Router.
A Telit board has been added, enabling operation with a 4G chip, transforming the RPi into a low-cost portable router for internet access.
Beyond internet access, this setup can serve as a data collector, utilizing Wi-Fi, Bluetooth, and USB ports to connect with local sensors in the environment, collecting data for transmission to the cloud.
There's a ton of potential to explore with this setup - you can use Raspberry Pi OS, different programming languages, databases, and more to build all kinds of software solutions.
It is also possible to connect a device via cable through the RJ-45 port.
A multi-color LED indicator has been added to provide a quick and easy visual indication of the device's current status.

Monet
Monet is an advanced network monitoring system capable of monitoring a vast number of devices (thousands), utilizing protocols such as SNMP, ICMP and API access.
It was developed using Python and C languages and featured an efficient mechanism for collecting data to monitor thousands of network devices.
Extensive use of threads, subprocesses, and queues allows for numerous simultaneous queries to devices, ensuring accurate and up-to-date counter values.
The microservices architecture guarantees stability and high availability. It is possible to scale the number of collectors depending on the number of devices to monitor, making the system highly scalable. All processes are optimized for high efficiency to extract the best performance while minimizing hardware and cloud service costs.
All metrics and raw data collected from variables (OIDs) can be exported to files in Splunk or ElasticSearch formats.
The web application is developed using the Django framework, which provides a robust and extensible interface experience.
Functionality and integrations can be easily expanded by extending the API.
The all data is stored in an Oracle database, with extensive use of caching and queuing on Redis.

Simcard Control
This tool is a database for storing records of routers and other devices capable of connecting to 3G, 4G, and 5G networks and managing their installed SIM cards.
It allows storage of data such as IP addresses, location, model, ICCID number, credentials, installation date, status, and carrier information, among other details.
The system periodically connects to each router to verify that the recorded ICCID numbers match those installed in the router.
Various reports provide compliance checks, locations of all installed SIM cards, status, availability, and more, making it ideal for managing deployments of thousands of 3G/4G/5G routers and SIM cards.
The system was developed using Python 3, the Django web framework, and an Oracle database. It accesses devices using various protocols (SNMP, SSH, API) depending on the device model, employing scheduled tasks for simultaneous connections to ensure rapid data retrieval.
It can be integrated, via APIs, with other systems such as ITSM platforms or custom systems to meet specific needs.
