I’m building an internal admin panel that will sit between our CRM and accounting software, pulling data from each via their REST APIs and storing it in a MySQL database. The goal is to give our team a single place to read, display, and, when authorised, update customer records across both systems without hopping between platforms. You’ll take charge of: • Writing clean, efficient API queries to fetch and push customer data to both the CRM and accounting endpoints. • Structuring the MySQL schema so the data coming from two sources remains consistent, searchable, and easy to update. • Wiring everything into Budibase (or a comparable low-code tool if you feel it’s a better fit) so staff can view and edit customer information through a secure, user-friendly interface. A solid grasp of authentication flows, error handling, and data-sync logic is essential so we avoid race conditions or partial updates. If you’ve already built dashboards on Budibase, tell me about them—otherwise show me similar work that proves your API and MySQL chops. I’ll provide API docs and database access as soon as we kick off, and we can iterate quickly from there.

Hello sir I can help you build the internal admin panel that bridges your CRM and accounting software. I’ve worked extensively with REST APIs, MySQL schema design, and low-code platforms like Budibase to create secure, user-friendly dashboards. Here’s how I’d approach your project: API integration – Write clean, efficient queries to fetch and push data, handling authentication flows, retries, and error cases gracefully. Database design – Structure the MySQL schema so data from both sources is normalised, searchable, and easy to sync/update without conflicts. Dashboard build – Configure Budibase (or suggest alternatives if it fits better) to give your team a single secure interface for reading and updating customer records. Data-sync logic – Implement safeguards against race conditions and partial updates, ensuring consistency across CRM, accounting, and the internal DB. I’ve previously built dashboards that aggregate customer and financial data from multiple APIs, with CRUD operations, role-based access control, and detailed logging for traceability. Happy to share examples on request. Once you share the API docs and DB access, I can start iterating quickly with you. Looking forward to collaborating. Best regards,

Hello! I understand your goal is to create an internal admin panel that seamlessly connects your CRM and accounting software via REST APIs, synchronises the data into MySQL, and presents it in a user-friendly dashboard (Budibase or alternative low-code tool) for your team. The key challenges here are structuring the database for consistency, handling authentication flows securely, and managing data sync logic to prevent race conditions or partial updates. Queries: Which CRM and accounting systems are we integrating (e.g., HubSpot, Zoho, Xero, QuickBooks)? Should updates be real-time sync or periodic batch sync? Do you require role-based access control (e.g., some staff read-only, others with edit rights)? I am looking forward to working on this project with you! Best Regards, Ravi

With over 8 years in Web/App Development and Designing, I have amassed extensive experience working with APIs, including the likes of Shipstation, Quickbook, Saleforce, and more. This means that not only am I comfortable handling API integrations for your CRM and accounting software, I thrive on it. My skills also extend to MySQL and PHP. These are essential for managing the flow of data between different systems in a way that ensures consistency and ease of use. What sets me apart from most is my ability to not just work with APIs but to understand them. Having built dashboards on Budibase before, I am intimately familiar with the intricacies of harnessing its power as well as its framework counterparts like Laravel, CakePHP, and CI. This means that I won't just tinker around till the solution works, but will proactively come up with ideas and solutions that might increase the efficiency or usability of your budibase application. Data synchronization logic is an area where any hint of negligence can deeply hurt usability. You can count on my meticulousness in designing everything from error handling to authentication flows to avoid race conditions or partial updates. Let's collaborate for a task that requires consistent yet powerful integration between systems!

Hello, I can build your internal admin panel that bridges CRM and accounting data through their REST APIs, normalizes it into a MySQL schema, and presents it in a secure, user-friendly Budibase interface. Questions: – Do you want updates to push instantly to both CRM and accounting software, or should staff have a “review/approve before sync” option? – Should the MySQL database serve as the system of record, or only as a cached/normalized middle layer? – Will staff need audit logs (who edited what, and when), or is that optional for now? I am a TOP Rated Freelancer, and you can check my reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project.

Hi. Your project sounds like a great fit. I’ve built several internal dashboards that connect CRMs, accounting tools, and MySQL backends, so I know the challenge of keeping two external systems in sync without race conditions. I’d handle the API integration with clean, modular queries, set up a schema that keeps data consistent but still traceable, and put proper sync and error handling in place so nothing gets lost or duplicated. On the frontend side, I’ve worked with Budibase before, though if you prefer more flexibility we could also look at Retool or a lightweight custom React panel. Either way, the goal is a secure, user-friendly interface where your team can manage everything in one place. Once you share the API docs and access, I can get started quickly and we can iterate together. Does that sound aligned with what you’re aiming for? Best, Benjamin
