Online-tilassa Offline-tilassa
I have working experience in the field of marketing & sales and skills/competencies acquirement. Until this point I have enjoyed the privilege to plan, coordinate, carry out and evaluate various projects, having a high sense of commitment and responsibility. In all cases I have set primary objectives and priorities as a cornerstone of my work plan, based on the available budget lines. In the past I have held team player positions, but also leading ones too. In any case I directed all my efforts to achieve overall and individual objectives. As a leader I used techniques of reward and recognition and team building in an effort to address diversity issues raised, related to the team's background. Regarding my IT theoretical background, I have a language free knowledge to software architecture and documentation using UML, but also to object oriented programming. In the mean time I have practiced basic knowledge in the programming languages I mention to my resume, so as to gain an initial familiarity and enhance my knowledge. When it comes to the modules that I have concluded and those I am working on, all include implementation of the theoretical aspects through exercise. I have managed to put in action my knowledge in Linux, and deploy a basic server configuration with Apache, where a wordpress website is uploaded. During my time in MachinePoint Ltd I had to develop a totally unknown to me market, demonstrating outstanding results. At the same time I was assigned various projects apart my main role in the marketing & sales department. I would welcome the opportunity to discuss the possibility to work for you and my own background in more detail, and would be available for interview.

Open University in the North (UK)

Introduction to Linux.

Software development with Java (2012)

Open University in the North (UK)

Description from the University's web page: [login to view URL] Discover the fundamentals of an object-oriented approach to software development. Starting from an analysis of requirements, you’ll be introduced to up-to-date analytical techniques and processes essential for specifying, designing and implementing a software system, including a graphical user interface. Although the small systems developed in the module have been chosen to facilitate learning, the underlying concepts are widely used by professional software developers. Software models are created with UML and implemented with Java 6, using NetBeans. You need Java experience, preferably by prior study of an OU Level 2 Java module.

Web technologies (2012)

Open University in the North (UK)

Description from the University's web page: [login to view URL] The World Wide Web continues to provide a foundation for the development of a broad range of increasingly influential and strategic technologies, supporting a large variety of applications and services, both in the private and public sectors. There is a growing need for management and decision makers to gain a clearer understanding of the application development process, from planning through to deployment and maintenance. This module will give you an insight into architectures, protocols, standards, languages, tools and techniques; an understanding of approaches to more dynamic and mobile content; and demonstrate how you can analyse requirements, plan, design, implement and test a range of web applications.

Building blocks of software (2012)

Open University in the North (UK)

The main aim of the course is to introduce you to some concepts underlying a systematic approach to software. It includes various forms of data (data structures) commonly used in software, such as sequences and trees. These are organised into data types and classes. We introduce a course code, which is a language to express instructions in a form suitable for execution by a computer. (The course code is implemented in a software package supplied as part of the course materials, which we refer to as the WorkPad.) The course code is not a specific programming language that you might meet elsewhere, but it does have features that are often found in certain programming languages (such as C++ or Java). It does not by any means have all the features present in such languages, though. Our aim is to deal with principles relating to the use of such languages, rather than with large-scale practical software development. We emphasise abstraction: the separation of the behaviour of a software element (given as a specification) and code to achieve that behaviour (an implementation of the specification). A few ideas from mathematics are introduced, where they assist in understanding software features. We introduce some ideas from symbolic logic, which is widely used in the expression of software requirements. We look also at some ideas relating to the structure of databases, and at a case study drawing on these ideas. Block 4 introduces recursion, a powerful tool for approaching certain problems. This final block also provides brief introductions to efficiency, and to methods to prove that an implementation is correct.

Object-oriented programming with Java (2012)

Open University in the North (UK)

The module continues the teaching about fundamental object-oriented ideas by investigating: - inheritance hierarchies - overriding methods - abstract classes - interfaces - polymorphism - re-use of code - static methods and variables. Along the way, you’ll learn about creating your own classes, about the facilities of Java for selection and iteration, and more about some of the core, provided Java classes. Different kinds of errors are discussed together with techniques for error handling, program design and debugging. After discussion of the need to design code, you will be expected to be able to implement to specification a class along with its methods. You will then be introduced to a subset of the Java collection classes, and related issues such as ordering and sorting. You are guided to apply the knowledge you gained from the first parts of the module, along with the new classes being introduced, to increasingly complex programming exercises. The skill of appropriately utilising a provided library of classes (searching for a useful class and method, for example) is explicitly developed in this context, and re-use by composition is discussed. The last part of the module begins by investigating how data is written to and from files in Java and how objects can be made persistent by writing them to file. Both of these techniques are useful in larger scale programs.

Introduction to the Music Business (2014)

Berklee X

Three things are clear about today’s music industry: The consumption of music is expanding at the greatest rate in history and from the most portals ever imagined, the cost of producing music is decreasing, and the number of artists creating and seeking to expose their work and develop careers through the Internet has increased dramatically. As demand grows and Internet piracy wanes, ad-supported and subscription models will generate unprecedented revenues that will surpass even the best of past earnings. And, many astute “music industry-watchers” predict a steep rise in business activity and trade earnings by the end of the decade. Whether you’re a music creator, consumer, or facilitator of this process, you’ll want to understand the history, underpinnings, and basics of the music business. This course has been developed to provide students with the latest instruction on the best way for creators, consumers, and facilitators to navigate the resurgence of one of the world’s most exciting industries: the music business. Course author John Kellogg—administrator, educator, entertainment lawyer, performer, and radio and television personality—offers students the opportunity to learn the fundamental principles of the developing new music business, for now and into the future.

6.00.1x Introduction to Computer Science and Programming (2014)


6.00.1x is an introduction to computer science as a tool to solve real-world analytical problems. Verify the authenticity of this certificate at: [login to view URL] About this Course This course is the first of a two-course sequence: Introduction to Computer Science and Programming Using Python, and Introduction to Computational Thinking and Data Science. Together, they are designed to help people with no prior exposure to computer science or programming learn to think computationally and write programs to tackle useful problems. Some of the people taking the two courses will use them as a stepping stone to more advanced computer science courses, but for many it will be their first and last computer science courses. Since these courses may be the only formal computer science courses many of the students take, we have chosen to focus on breadth rather than depth. The goal is to provide students with a brief introduction to many topics so they will have an idea of what is possible when they need to think about how to use computation to accomplish some goal later in their career. That said, they are not "computation appreciation" courses. They are challenging and rigorous courses in which the students spend a lot of time and effort learning to bend the computer to their will. Introduction to Computer Science and Programming Using Python covers the notion of computation, the Python programming language, some simple algorithms, testing and debugging, and informal introduction to algorithmic complexity, and some simple algorithms and data structures. Recommended textbook. The recommended textbook for this course is: Introduction to Computation and Programming Using Python, Revised and Expanded edition, by John Guttag (MIT Press, 2013).
