    E-commerce & Risk Advisor

    Malaysia - Last active: 09/27/2013

    E-commerce business owners face risks. Some may keep you awake at night. Others are routine and you really don’t think about them. The ones that keep you awake at night are most likely the least understood — or outside of your control. A key to business success is to mitigate your risks by better understanding the issues and how you will react to them. If nothing else, you may sleep better. Operational Risks If you have an established business that’s running smoothly, you still have risks that can slow your growth or halt your sales. These “operational risks” are ever present and frequently outside of your control. They could include the following. - Search engine optimization risk. Google changes its search engine algorithms and your website traffic drops by 50 percent overnight. - Hosting risk. Your website hosting company suffers a series of failures and your stores are offline for hours. - Price competition risk. Your largest competitor drops prices by 30 percent and your sales suffer. - Supplier risk. Your top-selling product line is suddenly pulled from the market and you are faced with a huge loss of revenue. - Shipping risk. A container load of products from an overseas supplier is stuck in customs because of a change in policy or an error in the shipping manifest — you have little inventory to sell. - Marketplace risk. You sell products on Amazon that it does not carry but it suddenly sources the products itself, at a much lower price. In those examples, the risk is not something you can directly control. Market forces, economic conditions, competitive strategies, and governmental regulation can impact your business. But, you can make contingency plans to mitigate the risks. For example, if you are heavily dependent on Google’s organic search traffic for your sales, make sure you understand which keywords convert and set up AdWords advertising campaigns that utilize those keywords and landing pages. In the event you are affected by an algorithm change, you can quickly turn on pay-per-click campaigns to remain visible to those searching on your keywords. If your competitors decide to lower prices, you need to be in a position to quickly respond. Consider how you might lower your prices in response, or introduce a campaign to emphasize your superior service, free shipping, or rewards program. The point is to take the time to identify the operational risks that would most impact your business. Think through ways to mitigate the impact if any of those scenarios were to actually happen. Make sure you prioritize. Once you deal with one type of risk, move it down the list and look at the next one. Assumptive Risks If you are a startup or expanding into uncharted markets or products, your risk lies in the assumptions you use for planning your new venture. You have to make assumptions, since you have little or no historical data to draw on. For a new eCommerce business, your assumptive risks will likely include: * Estimated website traffic; * Conversion rates; * Average sales order size; * Cost per acquisition from advertising; * Operating costs; * Gross margins; * Market demand for your products; * Cost and time to build out your website. As with operational risk, you must first identify the assumptive risks you face and prioritize them. Rather than first thinking about what to do if the results are different than your assumptions, you need to test your assumptions as much as possible to validate them. There are many ways to test assumptions. First, conduct industry research to determine as much as you can about your competitors. You can use tools to look at their website traffic and how they invest in pay-per-click advertising. You can research conversion rates for businesses operating in a similar space. You can also survey prospective customers or ask them to test a mockup of your website. If you are selling a single product or product line, you can test sales using different landing pages to monitor conversion rates. Do some polls in Facebook or Twitter or other social media channels. Interview other ecommerce business owners in non-competitive spaces. Ask them about conversion rates, seasonality, what their average order size is and so forth. You’ll find business owners willing to talk to you if they don’t see a competitive threat. I learn something every time I talk to another ecommerce company, even if I am the one supposedly providing the insight. I'm the best person to help you review your business needs and business focus + reducing risks you may face. You are welcome to join me to build your business revenue.

    CakePHP Application Architect

    United States - Last active: 10/02/2014 - Tests: 1

    I have been developing and managing websites and web-based applications for more than 18 years. I specialize in the architecture, development, and management of complex applications with CakePHP. In 1996, I started Protelligence, focusing on web development, Internet marketing, and website management. I closed the company at the end of 2002. In 2008, I returned to application development full-time for Haggin Marketing/Solutionset/Ryan Partnership. Most of my time was spent working on a custom CakePHP CMS used for the production of Adidas catalogs. The product cut the catalog production time by more than 65%. In addition to developing advanced features for the application, I led a major refactoring project so that the code met modern design practices, and coding standards. In addition, I was also responsible for most of the documentation, unit testing, and advanced CakePHP features. In 2011, I was hired as the Lead Architect for noblehour.com a social CMS that provided hour tracking for internships and volunteer work, as well as other social community features. I created a new plan and a flexible abstract architecture that allowed us to reach the first beta in four months. The new architecture resulted in an application that was 70% smaller, easier to use, and much easier to develop with. I primarily focused on developing the architecture and the core features of the CMS, while most of the team focused on writing the modules that contained most business rules and features for users. I have been contracting since August 2009 in a variety of roles for small to medium businesses and startups. I was hired as a project manager and interim Director of Engineering for Field Automated Communication Systems. In addition to project management, I was responsible for implementing Agile methodologies, JIRA, creating documentation, ERDs, UML diagrams, and wireframes for the application. Other projects involved architecture and software development as well as project management. I converted a third-party subscription application to a custom CakePHP application including the user signup, user management, recurring billing, and administrative features for a startup in the online storage space. Last year I worked with a construction hardware company upgrading and adding features to their CakePHP enterprise application. I also developed the architecture and code base for a business related gifting startup. Currently I am working on a multi-sides SaaS platform for a travel related site. In addition, For all of these projects, I implemented JIRA for project and issue management, version control, and a lightweight continuous integration and deployment system with phing. In addition to my programming and web development experience, I have a solid understanding of business, sales, and marketing that I have acquired over more than 20 years as an entrepreneur. This often allows me to bridge the gap between management and engineers.
