    Expert Web Developer (PHP / Yii / Laravel)

    Canada - Last active: 9 days ago - Tests: 3

    Almost 10 years of experience as a PHP Developer and a Dev Lead. Has been involved in a development of several successful internet start-ups in Russia. Nowadays I am working as a Web Programmer in BC, Canada. I believe that implementation of properly built software can dramatically improve efficiency of a business. This is the reason why I am so passionate about reliability and longevity of the products I make and the reason why I take any downtime personally. For the same reason I prefer to work on bigger and longer projects so I can better understand business processes and needs. I love automating processes so the business owners and employees can focus on the business rather than on tools they are using. I had experience implementing systems that reduced number of employees required to keep the business running by 50% and systems that allow cross-country companies to go paperless. I have solid experience in developing web applications from a scratch, as well as fixing other's code. Web development is what I do my whole life and I am looking for some interesting part-time projects to spend my evenings and weekends on.

    Expert Graphic Designer with over 6 years experience.

    Pakistan - Last active: 1 day ago - Tests: 6 - Portfolio: 27

    Over the past 6 years, I have worked with numerous national and international clients, helping them achieving their target customers and bringing them the required quality that their brands need. Your brand and product may be too good, but that can only be known after it has been used. Prior to that, it all comes down on your advertisement tactic, which primarly consists of your designed graphics. Proper graphic designing is an art, which I am absolutely capable of managing. I know the ins and outs of graphic designing, and the importance of unique, highly creative and attractive designs, which are the vital keys to your business's success.

Last 5 years I use Python, to create scalable, fast and reliable applications for serverside web, also I have deep knowledge in such python frameworks as: * Django, Django REST Framework, SQLAlchemy, Tornado, Spyne.

    Web Design & Google Analytics Consultant

    Germany - Last active: 6 days ago - Tests: 7 - Portfolio: 4

    I am an Irish web designer and online business consultant, currently living and working in Berlin. I am passionate about helping small businesses and startups achieve their business goals; whether through building ecommerce and service websites that perfectly serve your online needs, or using data and analytics to optimise online marketing strategies and maximise your resources. My skills have been acquired through over a decade of personal, hands-on experience. It was while working as a freelance fashion photographer in Dublin some ten years ago that I realised I was enjoying coding my website and learning online marketing strategies more than the actual photo shoots! I retrained as a social media strategist and Google Analytics consultant, and gradually honed my knowledge and skills until I became Director of Ecommerce for an international fashion label. It was during this period that I noticed the overwhelming number of decisions facing business owners and entrepreneurs trying to establish an online presence. Even the first step of setting up a website involves a huge range of decisions, from choosing a good hosting provider to finding the right platform to manage your website; all the while trying to manage the time and budget constraints that affect every business. I realised with my combination of web design and online marketing skills I was perfectly placed to be able help navigate this maze of options – so now that's exactly what I do. I am committed to clear, open communication, and my ultimate goal is a happy client. I treat each client's business as though it were my own and am dedicated to helping you find ways of taking your business to the next level, whether you're just starting out, or feeling in needing of a fresh strategy. Looking forward to working with you!
