It's just amazing! But I was working on EXACTLY same project (firmware + multiple APIs) for last 4 years for R&D department of world known corporation (Lock manufacturer). Lot's of aspects are still under NDA, so it's subject of discussion. Our board of choice was nRF52, I still own dev boards at my location. So, just imagine what you potentially will get: you will have an expert who was involved in 10 people team (hardware & software) spent 5 years of challenging of not similar, but IDENTICAL project. More: I'm available right now full-time (located in co-working space, my timezone is EET). What I need from your side right now is full description of the project with desired milestones.... your final date looks a bit optimistic, so I need to know which minimal functionality you expect to obtain till specified date. Looking for more details from your side. Best, Alex
