+<p>
+	I've grown up around computers and am intimately familiar with the operation of all types of digital systems.
+	I'm always happy to help set up new computers, phones, and tablets, or to assist in resolving problems that
+	have emerged. I understand exactly how important your data is--whether that's
+	your photos, your writing, or your work--and I'm always willing to
+	be flexible in my approach to engineering a solution that fits your needs.
+</p>
+<p>
+	As a programmer, I have thousands of hours of experience with every facet of Windows, MacOS, and Linux computers--
+	I've built multiple computers for my own personal use, and I maintain server hardware on premises to run my services.
+</p>
+<h2>Examples</h2>
+<ul>
+	<li><p>Configuring cloud storage</p></li>
+	<li><p>Backing up photographs</p></li>
+	<li><p>Decluttering/improving performance of old computers</p></li>
+	<li><p>Tech education/explaining the optimal use of systems</p></li>
