Michael Y

Michael Y Agency Contractor

Sr. Systems Architect, Mathematician-Astrophysicist and Bio-Geneticist

Canada - Tests: 2 - Portfolio: 5

My purpose is to lead, strategize, guide, direct and architect problem resolutions for individuals and organizations using self-sustainable philosophy and decision-making, in order to establish complete systems and processes of solutions that work. My vision is to ensure in every household, institution or establishment, intuitive and organic integration of real-time problem-solving becomes second-nature to the operating environment. I intend to achieve this using my unparalleled knowledge and application of the Synergy between Business Intelligence, Technical Excellence and Organic Sustainability. In other words, I solve problems, using fundamental building blocks that most people and organizations overlook, yielding solutions that can adapt to their environment in real-time. Problem-solving processing can lead multiple resolutions to several problems whereas "a solution" to a problem itself only, usually yields a new problem that need be solved with other solution(s) which may or may not be found within the given scope. This cycle can be vicious and critical but is easily overcome by what we call the "Process" or "Spiral" at Don Sigma Corp. This so-called "Spiral" allows us to solve problems that solve other problems by drawing Synergy between resolutions and fundamental building blocks. With this know-how and several other particulates of Don Sigma Corp.'s unique knowledge and technology at my disposal, you're just a contact away from experiencing your dreams come true.

Carl Hinton

Carl Hinton

Senior Drupal Developer

United Kingdom - Tests: 2

Over 25 years’ experience in I.T. design, build, consultancy and project management, in both public and private sectors. I am not looking for permanent work. Just a little extra to fill my time whilst sitting on my very long daily commute. I have worked in collaboration with a number of high profile high street names including Apple, House of Fraser, Argos and Thomas Cook and in the public sector including the United Nations and the National Trust where my responsibilities included leading the end to end design, build and coding of Drupal websites. My Drupal based websites have won prestigious awards. I have security clearance. DRUPAL I have ten years of experience with DRUPAL 4, 5, 6 and 7 having used it for content management of a large number of sites that I have used to support a diverse range of web projects ranging from government websites to large community-driven charity sites. My knowledge includes creating modules for DRUPAL. I often contribute to the Drupal community – my username is CarlHinton where you will find I head up the group responsible for maintaining the Swahili version of Drupal and I am heavily involved in the Drupal 8 build. I am a member of London Drupal meetup group. PHP MySQL & phpMyAdmin Experience I have over 17 years continuous practical experience in this area. Examples include prototyping of the Goldfish card platform (1.9 million card-holder accounts) using MS-Access, then conversion of this prototype to mySQL, design of multi-tier through to web interface, including server balancing. I have extensive additional multi-tier database experience, in particular use of LAMP, (Linux, Apache, MySQL, PHP) and CITRIX. One example is the Barclaycard Partridge database. I was responsible for the requirements gathering, designing, coding and implementing of this database. The database is used over international boundaries, holding 1.7 million secure customer accounts. Completed within a timescale of two months, Partridge now has in excess of 5,000 concurrent users. Others examples include the on-line banking systems for Argos, Sky, House of Fraser and Thomas Cook each system having in excess of a million users. Developing and Implementing Systems I have practical experience of all stages of the software development lifecycle. During 2004 I designed, prototyped and wrote code (Visual BASIC and C++) for the Barclays Connect transactions database this is still in use with 50 concurrent front line users. I believe that this demonstrates the robustness of my VBA design. I am the creator of an on-line Artificial Intelligent distributed databases for the CBM (an international charity organisation). The requirements for this database have been changing almost daily since its inception. The easy maintainability of this system is demonstrable from its continued existence. Analytical Skills I have worked both alone and as part of teams of professional change analysts for over twelve years, using ISEB, Prince 2 and Agile Volere structured methodologies to identify and deliver enhancements and improvements across both public and private sector organisations. Examples of my Analytical skills include: Drupal project management Large organisation change management working across Barclays Bank ISEB Analysis techniques for Skycard and Providian Prince 2 Project management techniques used for many years across many projects in both Barclaycard and Barclays Bank Financial trend analysis for five years in Barclaycard Terminal Operations Programming Numerical Algorithms / Module Construction I have extensive knowledge of programming numeric algorithms, particularly in the Drupal environment. For the Barclays Controls Review it became necessary to develop a group of functions within this environment which could readily be describes as a programming language in its own right Interface Design I am familiar with Human Computer Interaction (HCI) techniques for making user friendly GUIs, and all of the systems mentioned above included requirements for the disabled and non-English speaking users. In addition I used HCI with Ie (subsidiary of TSYS) in the development of the Apple credit card website. Working corroboratively and on own I am experienced in working in a collegiate manner as well as being self directed when appropriate. Collaborative Projects: Design and Development of Requirements Definition for Sky Requirements gathering for systems for Thomas Cook and Argos Systems use cases (ISEB) User Acceptance Testing, Test strategies, scripts and scenarios End user, Business Owner, and Process Owner Interview Personal Projects: Organisational structure redesign Scenario Modelling Benefits planning / Business cases for multiple Barclaycard projects I have been self-managed for over 20 years
