    Senior Project Manager/Product Developer

    United States - Last active: 23 days ago - Tests: 2 - Portfolio: 10

    I have a comprehensive background in product development/project management within the confines of international medical device regulations. I thrive on taking vague ideas and ill-defined needs and turning them into concrete reality. I can start a medical device company from the ground up and I can do it on schedule. This includes... From a Regulatory perspective: --Initial regulatory requirements analysis for new markets (EU, Brazil, Australia, US, Canada, etc.) --Identification of applicable test protocols (ISO standards, etc.) and management of test houses --Interfacing with regulatory agencies and identifying consultants --Writing of regulatory submissions such as FDA 510(k)s --Quality System development and implementation to required standards (ISO 13485, FDA, CMDCAS, etc.) --Identification of loop holes and temporary workarounds to ease implementation pains and maintain profitability From a Project perspective: --Using good interpersonal skills to keep people motivated and excited --"Conducting the orchestra", developing a logical rhythm of events and ensuring timely completion of tasks --Turning "unknown unknowns" into "known unknowns", forseeing problems before they arise and altering the "orchestra" accordingly --Coordination of teams on an international level --Intelligently focusing energy on tasks with the highest variability, including procurement of additional expertise as necessary --Always keeping an open dialog about the day-to-day changes in the "Good/Fast/Cheap, pick any two but only two of the three" trade-offs in milestone achievement From a Product perspective: --Development of design parameters from organization input (Sales, Marketing, Support, etc.) --Nitty-gritty technical work like engineering drawings/drafting, statistical analysis, resdesigns due to manufacturing constraints, component supplier identification. --Identification, qualification, and day-to-day management of international manufacturers --Design History File/Technical File development and maintenance --Design Transfer for complex electromechanical devices From an Operations perspective: --Part Number/Drawing Number/Revision Control development and implementation --Engineering Change Order workflow and impacts --Purchasing-Manufacturing-Sales-Shipment procedures and throughput --ERP/MRP implementation including workarounds for system limitations I am a strong believer in a person's word. If I tell you I'm going to do something by a certain date that is my word and I'm going to get it done, hell or high-water. I don't mess around: I live on a remote homestead so I grow my own food, build my own structures, fix my own car, brew my own beer. My entire life requires a high level of precision execution every single day, failure is not an option.

    Full-Stack Developer - Troubleshooter/PHP/Javascript

    United Kingdom - Last active: 2 days ago - Tests: 5 - Portfolio: 1

    With a strong technical background in both Windows and Linux server administration, I consider myself to be a highly skilled internet & technology all rounder. Combining both experience and knowledge I can quickly identify and assess customer/client needs and find solutions to suit their requirements. I have been working successfully as an independent remote contractor for over 7 years and have built up particular strengths in MS server products especially SQL Server & IIS - with strong coding skill in javascript/jquery, PHP and experience in many other broader web technologies. I pride myself on being a fast learner and just enjoy making things work. I have been able to maintain long term relationships with my clients and am eager to continue to do so having recently completed a long term contract at another oDesk employer. Having worked in corporate IT for 7 years in a very high service availability environment, I know how to work under pressure whilst adhering to process. My key personal strengths include a keen attention to detail, excellent troubleshooting skills and an easy-going demeanour that helps me build strong working relationships quickly.

    PHP,HTML,CSS,Java,JavaScript,Perl, Web Developer, MySQL, Linux: 10+yrs

    United States - Last active: 1 day ago - Tests: 6

    I have over 14 years of experience building, fixing and maintaining web applications and their back-ends (large and small). Web programming is my bread and butter- HTML/CSS and whatever drives it on a LAMP or LAMJ stack (PHP, Java/JSP, JavaScript, Perl, etc.). Plus I can administer the technology needed behind the scenes for database setup (MySQL and postgreSQL), maintenance, cron jobs, and systems administration (RedHat/Fedora/Centos or other Linux, etc.) Whether you have just a quick need for someone who knows their stuff, or a larger or ongoing project that might require recurring tasks, I'm here to help. I'm not a Jack of ALL trades, but I also am pretty savvy when it comes to website UI design, SEO and internet marketing, including email and social media.
