It is the ability to define a system’s architecture, components, interfaces, and data to meet a set of functional and non-functional requirements. It's not just about knowing technologies, but about making design decisions based on trade-offs (cost, performance, scalability, maintainability, etc.) to solve a business problem in an effective and sustainable way.

Ultimately, it covers everything from high-level architectural decisions (such as defining the overall architecture to use, how to organize and communicate services, and how system components interact) to low-level, detailed design of sustainable and adaptable code that represents business concepts.

System Design

Persistence in system design refers to the capability of the system to store data in a manner that it survives power failures, crashes, or errors. It's a critical aspect of any system design.

Persistence

Observability refers to how well internal states of a system can be inferred from its external outputs. It's crucial for understanding system performance, identifying issues, and ensuring optimal operation.

Observability

Infrastructure refers to the fundamental physical and virtual resources supporting a system. It involves hardware, software, networks, and facilities necessary for system operation and management.

Infrastructure

Testing is a critical phase in the system design process where the system is evaluated to ensure it functions as intended, maintains performance under different conditions, and detects any flaws or errors.

Systems Engineer and Software Developer. Since the beginning of my career, I've always had a focus on Backend technologies, although I'm also comfortable as a Fullstack developer. Throughout my professional journey, I've worked with technologies such as Laravel, modern object-oriented PHP, Docker, MySQL, MongoDB, Redis, Doctrine, Blade, Vue, Typescript, NodeJS, React, and AWS.

PHP (Hypertext Preprocessor) is a widely-used server-side scripting language designed for web development. It seamlessly embeds within HTML, making it ideal for creating dynamic web pages and applications. PHP executes on the server, generating dynamic content like databases, user authentication, and more. Known for its simplicity and extensive community support, PHP is a foundational technology for countless websites and web-based systems.

NoSQL databases, non-relational by design, provide high scalability and flexibility. They are ideal for handling large data sets and non-structured data. Examples include MongoDB, Cassandra, and CouchDB.

Clean code is a development practice focused on writing code that is easy to understand, read, and modify, with the aim of improving software quality and reducing complexity, facilitating maintainability and system evolution.

Clean Code

Monolithic architecture is a software design approach where all application functions reside in a single instance or component, simplifying development and testing.

Domain Driven Design

Redis is an open-source, in-memory data structure store, used as a database, cache, and message broker. It supports various data structures and provides high performance.

Redis

Relational databases use a structured, tabular format to store data, enabling complex queries and relationships. Examples include MySQL, PostgreSQL, and Oracle.

Relational Databases

Profiling Performance

Log management entails the process of generating, transmitting, storing, analyzing, and disposing of log data from different sources. It's essential for troubleshooting, security, compliance, and understanding user behavior.

Log management

Application monitoring involves tracking the performance and functionality of software applications. It aids in the early detection of issues, ensuring smooth and efficient application performance.

Application monitoring

Caching is a technique for storing data in temporary storage areas, or 'caches', to improve data retrieval speed and system performance, reducing the workload on primary storage resources.

Caching

Message Queues allow different parts of a system to communicate and process operations asynchronously. They provide temporal decoupling and load balancing, ensuring reliable data flow.

Message queues

Application scalability

Unit testing focuses on validating individual components, functions, or classes in isolation to ensure that each part of the system operates correctly and handles expected inputs and outputs.

Unit testing

Integration testing evaluates how well different components or modules of a system work together, ensuring seamless interaction and identifying issues that may arise from their integration.

Integration testing

Advanced PHP concepts include OOP (Object-Oriented Programming), design patterns, exception handling, and working with databases to build complex and scalable applications.

PHP Advanced Concepts

PHP performance optimization involves techniques like code profiling, caching, database optimization, and server configuration adjustments to enhance the speed and efficiency of PHP applications.

PHP Performance

Composer is a PHP dependency management tool. It simplifies the integration of external libraries and packages into PHP projects, ensuring efficient code reuse and maintenance.
