Ask HN: Software Engineering for Professionals – talk ideas

Where I work, we're seeing more professionals (operations engineers, production engineers, accountants, geophysicists, scientists, ...) working on developing their own 'applications' for reporting, visualizations and data analytics.

I thought it'd be good idea to give a talk about software engineering to help them better understand the tools, architecture, trade-offs, ecosystems and such.

Any thoughts on what to include and how to make it more appealing to a wide audience?
