Graphic Designer - Printing Specialist

United States - Last active: 3 days ago - Tests: 2 - Portfolio: 22

Creative, Experienced, Real World Graphic Design, Typography and Copywriting. Have you ever hired a graphic designer, only to have them come up with something so elaborate that you couldn't afford to print it? That is because they didn't understand the printing process or the capabilities and limitations of the equipment that you planned to produce it on. That is where I come in. I have spent my career in graphic design and possess a strong printing background. Don't get me wrong, I love to design the tricked out invitation or presentation with foil and embossing and spot varnishes and die cutting and gluing and lots of pantone and metallic inks - only problem, it is not in most budgets. Graphic design is about ideas, but it is also about details. I like to think that I am good at both. The greatest idea can fall flat if it is not properly executed - typography, spelling, use of photography, consistent branding... all are important to a successful project. As a designer, I had to learn that not every job is a masterpiece, that time is money and clients need to work within deadlines and cost constraints. So I learned to take my ego out of the job and adapt to customer needs. The first step in every job is to determine what it is that you need and then to create a compelling design that fits your parameters. I have spent many years in the advertising and printing fields. Both of these businesses gave me the opportunity to work with people in all types of industries - from small business to huge corporations, retail to manufacturing, service businesses to restaurants, tradesmen to professionals - I have designed for them all. So what are you looking for? Brochures, Flyers, Catalogs, Magazines, Books, Letterheads, Envelopes, Business Cards, Business Forms, Menus, Table Tents, Advertisements, Invitations, Door Knob Hangers, Packaging, Labels, Presentations, Annual Reports, Logo Design, Corporate Identity Packages - if it ends up as ink on paper I have done it and would be happy to create something for you - on time and on budget.

Experienced Webmaster/Web editor/writer/Copywriter...

Sweden - Last active: 1 day ago - Tests: 6 - Portfolio: 3

I am French (bilingual italian) and I have been living in Sweden since 2011. I am currently looking for a position corresponding to my experience either as a Writer/ Webmaster/Copywriter/Proofreader or translator /SEO translator (ideally working from home). After an extensive period of training (in Languages, Literature and Multimedia), I have been working for the last 15 years in the Web sector where I held several different positions (webmaster/web editor/writer/proofreader/copywriter). Over the years, I had to face the permanent challenge of adapting my work to ever changing demands from clients while staying as close as possible to the fast-moving requirements of the media sector. This challenge gave me the opportunity to develop and deepen my skills further allowing me to match as closely as possible the ever demanding needs of the sector. Thus, my skills have become over time more technical and graphic-oriented, although the text itself has remained at the core of my work. A genuine sensitivy for literary work - and more generally literature - meant that my professional work has always been guided by a true concern for rigour and conciseness. Finally, I had throughout my life the opportunity to live in different countries and to evolve in various cultural environments. This gave me an ability to adapt quickly to people as well as circumstances and to develop the open-mindedness required in today’s multicultural world.

Team Lead, Senior Ruby on Rails, co-founder at RM

Ukraine - Last active: 21 days ago - Tests: 1

I'm a Tech Lead with about 8 years experience in web-development and about 4 years in Ruby on Rails. I have in portfolio more than 40+ finished rails projects from social platforms and e-commerce to SaaS. I'm self motivated, can solve complex tasks in a short time. In the past two years my main roles were architecture planning, choosing the right technology stack using the client's requirements, development management, team management I like Agile and use it every day - iterations, scrum daily meetings, retrospectives. I like confident code and TDD/BDD. I'm experienced in RSpec, Capybara and Cucumber. Often I help clients to understand what will be the best development approach for them. Do they need only MVP or there is a sense in building full version. What technologies are best for their project. Plan deadlines and budget. I'm very familiar with AWS technologies stack - setup EC2 instance from scratch, configure balance loader(EBL), setup push notifications service(SNS), emails(SES), database instances(RDS), and other services I have an experience in buiding a high-load applications, huge processing centers with 1,000,000 processed jobs daily(in Sidekiq), PostgreSQL database size more than 500GB and everything places on EC2 instance with 32 Cores and 68GB RAM. That was very excited. I'm a fun of continues integration and continues deploy practices. I also have experience in front-end development: JavaScript on advanced level, canvas, CoffeeScript, web-sockets(socket.io) with node.js back-end, backbone.js, Ember.js In the past years there is a trend to have an application with RESTful JSON API built in Ruby on Rails. I have experience in building more than 5 different APIs for different projects. Some of them were versioning and have up to v4. There is always a challange to support old versions, but we successfully doing it. Some have HIPAA protection, one application had a really complex structure of API URLs but it was very easy to work with it in the end since we built it human readable. Thanks for you time!
