+    \begin{itemize}
+      \item BSEE and MsEE at University of Central Florida
+      \begin{itemize}
+        \item Research work in hardware security
+        \item PCB design, FPGA work
+      \end{itemize}
+      \item Electrical engineer at STERIS IMS
+      \begin{itemize}
+        \item Reverse engineering medical devices
+        \item Design, layout, testing of replacement PCBAs
+        \item High speed, some high density, FPGA
+        \item Tons of protocols (SPI, I2C, UART, SWI, SWD, SBW, USB 2.0, JTAG, MIPI CSI-2, HyperRAM, NFC Type V)
+        \item FPGA stuff, image processing
+      \end{itemize}
+      \item Side jobs/projects
+      \begin{itemize}
+        \item A little bit of everything
+        \item Two side jobs
+        \begin{itemize}
+          \item Fluorometric Instruments, industrial chemical sensors
+          \item Cassina Technologies, company one of my coworkers runs on the side
+        \end{itemize}
+        \item Mixed signal design, FPGA, some RF design
+        \item Working on the mechanical design for a CNC right now

+    \frametitle{Optical communications project}
+    \begin{itemize}
+      \item I designed this years ago, hindsight is 20-20
+      \item Design parameters
+      \begin{itemize}
+        \item Low bitrate unidirectional communication
+        \item Moderate range
+        \item White LED for transmitter, photodiode as receiver
+        \item USB interface
+      \end{itemize}
+      \item Objectives
+      \begin{itemize}
+        \item High dynamic range (want to be very tolerant of beam angle)
+        \item Huge emphasis on noise analysis
+        \item Highly flexible (I have no idea what I'm doing and I don't want to pay for a second board spin)
+        \item Let's do a lot of signal processing because I don't know a lot of that

+          \item Also Analog Devices Design Note 399
+          \item TIA with some extra bells and whistles
+          \item Lots of noise analysis, some stability analysis
+          \item BJTs act to remove voltage offset
+          \item JFET acts as a low noise bootstrap to reduce effect of photodiode capacitance
