About

Alexsander Fonseca

Hi, my name is Alexsander, author of Learn in Practice.

I'm a technology professional with a background in infrastructure and networking. Over the years, I've worked in complex corporate environments and technical projects involving the operation of critical platforms, infrastructure architecture, and troubleshooting in distributed systems.

I currently focus my studies with a special interest in Kubernetes, OpenShift, distributed platforms, high availability, clustering, storage, and cloud infrastructure architecture.

Learn in Practice emerged as a space to organize and document this ongoing learning process.

About the project​

Over time, I realized that documenting technical decisions, experiments, and investigations of complex problems was one of the most effective ways to consolidate knowledge.

This site was born from that practice.

Here I gather technical labs, conceptual studies, troubleshooting scenarios, and architectural analyses that reflect my journey of deepening expertise in infrastructure and cloud computing.

Although it started as a personal study repository, the project was structured more systematically, aiming to bring technical learning closer to the reality of corporate environments.

Learning philosophy​

Much of systems engineering is learned by investigating real systems.

Failures, inconsistencies, dependencies between services, and architectural limitations often reveal more about a system than its formal documentation.

For this reason, much of the content published here takes the form of investigative labs or troubleshooting scenarios, in which different components interact and produce complex behaviors.

Goal​

Learn in Practice was conceived as an open lab for applied technical study.

The project brings together technical scenarios, experiments, and investigations that seek to reproduce challenges found in real infrastructure and distributed platform environments.

Through technical labs and troubleshooting scenarios, the site explores how complex systems behave, fail, and are corrected in operational contexts.

The intention is to encourage a learning approach based on technical analysis, experimentation, and structural understanding of systems.

Community and interaction​

This is an independent project. The intention is for the published labs and studies to serve as reference material or discussion for other professionals interested in infrastructure and cloud computing.

Comments, technical observations, and discussions are always welcome.

About responsibility​

The content published on this site is made available for educational purposes and technical knowledge sharing.

Although there is an ongoing effort to maintain accuracy and consistency, there are no guarantees regarding completeness or suitability for specific environments. Any implementation should be validated in controlled environments before use in production.

This is an independent project, with no advertising and no direct commercial purposes.

About the IPESC initiative​

Learn in Practice is linked to the IPESC — Institute for Research in Computer Systems Engineering initiative.

The IPESC initiative is a long-term proposal focused on applied study, technical investigation, and dissemination of knowledge in infrastructure and computer systems engineering.

Regards,
