Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language supported by Apple for the macOS, iOS and iPadOS operating systems, and their respective application programming interfaces (APIs) Cocoa and Cocoa Touch until the introduction of Swift.
Objective-C is a thin layer atop C, and is a "strict superset" of C, meaning that it is possible to compile any C program with an Objective-C compiler, and to freely include C language code within an Objective-C class.
The Objective-C model of object-oriented programming is based on message passing to object instances.
In Objective-C one does not call a method; one sends a message. This is unlike the Simula-style programming model used by C++. The difference between these two concepts is in how the code referenced by the method or message name is executed. In a Simula-style language, the method name is in most cases bound to a section of code in the target class by the compiler. In Smalltalk and Objective-C, the target of a message is resolved at runtime, with the receiving object itself interpreting the message. A method is identified by a selector or SEL ? a unique identifier for each message name, often just a NUL-terminated string representing its name ? and resolved to a C method pointer implementing it: an IMP. A consequence of this is that the message-passing system has no type checking. The object to which the message is directed ? the receiver ? is not guaranteed to respond to a message, and if it does not, it raises an exception.

CEO & Full Stack Developer
"I believe in motivated teams used to work together. When everybody is in sync, better decisions are made, the focus on the final goals is never lost, and project development is much easier."
CTO & Full Stack Developer
"There are great ideas, cool technology, very nice design but those are only tools to build a product and the product is only a good product if it has results."
UX / UI Consultant
"Designing has a lot to do with common sense. To design highly functional and attractive interfaces and websites, you must understand your client’s business and the end user’s goals and motivations, and never lose focus on what is important."
Full Stack Developer
"When you see that your code runs successfully is when you realize how much you have learned and outgrown the you from yesterday. Giving up is not something you should ever tell yourself. Keep working and you will get there"
"Transforming ideas into memorable interfaces, blending innovative design and cutting-edge technology to create exceptional digital experiences."
"Computing has no end in itself, its purpose is to help humans to do their job. A developer is not only a coder, but someone who is willing to know about everything that is needed to reach that goal, every new system is a deep dive into some field of human knowledge."
Full Stack Developer
"Coding is not just writing a few lines to meet requirements. You need to be cohesive so that other people understand your ideas, so it's almost like writing a book...except for the fact that you can't forget the semicolon at the end of the line."
Full Stack Developer
"What drives me most is to use my creativity and energy to develop tools and processes that help people manage their tasks more efficiently and effortlessly."

Nuno Silvério Marques
Global Marketing Director at Reckitt
"I love working with Manuel. He adds strategy to his design skills and a sense for what works. A design brief can easily evolve to a brainstorm, with great new ideas being generated every time. Design works when the message is clear and the target nods their head."
Vasco Camara Pereira
Solution Architecture Leader at OutSystems
"Working with Filipe is believing that the work will be done on schedule, on budget and with extreme quality! Nowadays the technologies are a moving target and we don't have time to be up to date to every state-of-the-art piece of framework or tech launched. However, for Filipe, there isn't a single challenge that can't be done. I trust him and his team."
Diogo Dantas da Cunha
Founder and CEO of Flexty
"Working with Filipe you get so much more than a FullStack developer. At times I felt he knew more about the business than myself. He always questions decisions and forced good development briefings. In fact he was always more worried about understanding the big picture and customer side before diving into the development needs and that makes all the diference. With Filipe you get a business partner that is also a full stack developer. Thank you very much, it was a pleasure working with you."
