Contributor for book "Machine Learning Engineering" by Andriy Burkov.
My name is Vinicius Gamaliel, and I am a senior software developer with more than 12 years of experience in web development projects. Over the years, I have worked with small, medium, and multinational companies, building complex back-end and front-end solutions. My passion for my work and my adaptability to new technologies have enabled me to continuously improve and learn throughout my career. I can get involved in the entire development process, from planning to deployment, thanks to my experience. I am always ready to take on new challenges and find innovative solutions to complex problems. Therefore, if you need a dedicated and experienced software developer, I am the right person for the job.
I've been working in this field since 1998, programming in a variety of languages, including Java and C#. I have taught professional courses designed to meet the needs of reputable organizations.
Everything in this universe, in my opinion, is programmed; even atoms are programmed to join together to form molecules. I always do my best to solve problems programmatically.
Generalist Software Developer and Software Development Coach. I think testing is very important; a tight development process is key; and that reviewing your requirements regularly for completeness, consistency and accuracy will minimize the cost of "surprises". I like to know the big picture, am detail oriented and love the challenge of jumping into projects where I know little or nothing about the problem domain or technology stack. I believe in learning something new every day and that process improvement is all about being intentional with your time and effort.
I find mentoring others to be very rewarding, especially when the mentee finds that "ah-ha" moment and is able to move on under their own steam. I tend to seek out projects where I can dive in first and discover what is needed to bring the rest of the team up-to-speed.
I also love experimenting with new languages - some of the more recent examples are Rust, elixir and clojure. It's refreshing to see the newer languages are "batteries-included" in terms of build tools, test tools and dependency management.
I have expertise in **java 8 programming, functional programming with multithreading**. i have worked in spring boot, hibernate, microservice, apache kafka.
