Knack Database Modifications - 4

Please read very well before bidding. I will not look into automated replies and people who do not have the time to look into the details written here. I have a working database created by Knack. I need some modifications and customization that are beyond Knack tools and capabilities. The bidding developer MUST have past knack experience (please send me photos for example of your Knack work) and is required to have worked before with Knack databases and API. Please I need serious guys who are willing for a nice ongoing job and are responsive and trustworthy. I DO NOT and will NOT communicate on any other channel. NO EXCEPTIONS. Only FreeLancer work, Freelancer chat, and Freelancer terms, and I do not accept private offers. I AM SERIOUS. THE MOMENT YOU ASK ME BY ANY MEAN TO WORK ON ANY OTHER CHANNEL, TRANSFER MONEY OUTSIDE FREELANCER.COM, OR WORK FROM A FRIEND ACCOUNT OR ALL THAT SCAMS, YOU WILL BE REMOVED FROM THE PROJECT, REPORTED, AND ALL WORK WILL BE CANCELLED. Please do not waste my time if you plan to do any of this. I have tried many developers and I see there are many games here. I appreciate people with serious intent to work and reasonable availability. I pay on time once you deliver and I test the job required. I expect a range of 10-20 hours of work for the next 3-4 weeks. Then I might add requirements if I like the quality of the job and the communication of the freelancer. The database is created by Knack and customizations are made either on Knack Platform or on my GoDaddy server. Bidding developers should have accounts on both. I Will not pay for subscriptions. You must have your own accounts. Please do not bid if you do not have accounts on both or if you do not have previous Knack experience.
