Alright, let's tackle this. The user wants me to determine an hourly rate based on Rich Adili's profile. Let's break down the info.

First, his skills: Embedded Systems, Software Development, C++, C, Unix, Linux, Perl, Agile, Cloud Computing. These are all solid tech skills, especially in embedded systems which can be niche. C++ and C are widely used in that area, so that's a plus.

Experience: He's had several roles. The most recent is Senior Software Engineer at Tripp Lite. Before that, Imaging Group Leader at Cummins Allison for 3 years, Embedded Group Manager at Pro-Face INDE for 8 years, and Software Engineer at Union Special. Wait, the Union Special duration says 100 years—that's a typo, but maybe it's 2000? Probably 1900-2000, so 10 years? But that might be a mistake. Maybe the user meant 1990-2000. Anyway, he has significant experience, over 20 years in total if we consider the other roles. Senior roles like Group Leader and Manager indicate leadership experience, which adds value.

Location is Greater Chicago Area, US. Cost of living there is a factor. Tech salaries in Chicago are decent but maybe a bit lower than SF or NYC. However, embedded systems engineers with his experience can command higher rates.

Looking at current market rates for Senior Software Engineers in embedded systems, especially with leadership experience. In the US, senior engineers might charge $80-$150 per hour. Since he's in a senior role and has management experience, maybe towards the higher end. Also, considering the specific skills like Embedded Systems, C++, and Cloud Computing, which are in demand.

Possible factors that might push the rate higher: niche skills, leadership roles, long tenure. The typo in the Union Special duration might be ignored since the other roles add up to around 3+8+ (assuming Union Special was 10 years, but even if it's a mistake, the other 11 years plus Tripp Lite's unspecified duration. Maybe total around 15-20 years? That's substantial.

So, putting it all together, I'd estimate around $120-$140 per hour. Maybe average it to $130. But let me check if others agree. Some sources say embedded systems engineers average around $60-$100, but senior roles with management can go higher. Maybe $120 is reasonable. Alternatively, if considering contracting rates, sometimes they are higher. Let's go with $130.
