Business/Technical Consultancy

Although seemingly small and straightforward, tasks such as running reports, creating pivot tables, or matching items can quickly add up and drain your business of revenue. These activities may seem insignificant on their own, but in aggregate, the increased complexities can lead to burnout and high turnover rates.

Maintenance & Support

If given the opportunity to build a solution for your business, you have the option to choose an internal team or an outside party to ensure that the solution is always up and running. Alternatively, I can also provide ongoing maintenance and support on a monthly, annual, or multiyear agreement basis.

Data Processing/Analytics

Transactional systems, data warehousing solutions, machine learning, statistical analysis, and dashboards are just a few of the things my customers are looking for. Whether it's one or all of these solutions, the sky is the limit and I can help you get there.

Technical Requirements Discovery

Have you ever been told by a developer that a request was 'out of scope' during development, or that an unwanted result was not a 'bug' in the solution? If so, you know how frustrating and costly it can be to have to go back and forth with developers over simple requests or errors.

Systems Integrations

Do you need to update your product catalog from your supplier's inventory for your online drop shipping store? Or do you need to manage your active contractors in Workday while using SAP Fieldglass for contingent workers? I can help enable your systems to communicate with each other seamlessly streamlining your operations.

Project Management

As an experienced developer, I can effectively communicate with your development team in terms they can easily understand, provide valuable feedback to prevent delays, and hold them accountable to realistic timelines and cost estimates, ensuring that your projects are completed efficiently and effectively.

The site includes a live-chat function which allows you to either engage in real-time conversation with me or leave a message for when I am online. However, if you do not provide contact information in the live chat, it may be challenging to get back to you unless you regularly check the website. Alternatively, you can use the contact form to send me an email if I am not available through live-chat. Moreover, this feature was primarily built for fun rather than functionality to the site.
