Hi,
I am an expert software architect and developer with over two decades of experience. Experience includes programming to collect and manipulate data from process control equipments and other peripheral devices like web-camera, POS machines, card readers.
Please let me know what devices you were considering, and a brief on the application required, so I can provide you an exact estimate of the time required.
Look forward to hearing from you.
Thanks,
Sri.
UPDATE after your clarification regarding devices:
I would estimate between 25 to 30 man-hours of actual coding work. The project could be completed in a period of between 2 to 3 weeks, which would include, discussions, communications and trial runs, feedback and modifications.
I am assuming that the devices under consideration export data in some or other format, whether over wire or wireless or any other medium, and that can be imported into the website.
I have also digitally signed the NDA.
It would be convenient, if milestones were released after submission of work/proof every 5 man-hours.
Thanks,
Sri.
