MySQL DBA Projects

JQuery toggle to display specific records in a database table

I have a register of members displayed as a simple jQuery table on a website which pulls from a MySQL table. I would like a series of toggles displayed above the table which, when pressed will update the table to display certain records. The database records are all specified by an unique id number. As a result, I would like it so when an user toggles 'x', the table will automatically update just to display, for example, records that have the id number of 5 and 22. After the work is complete, I need to be able to change the id numbers that each toggle displays.

Laravel Developer Needed Ongoing Support

We have an existing Laravel + MySQL web application that provides access to a paid relationship assessment. The system is already built and live. It is hosted on Hostinger and access is integrated into our website which is Wordpress. The original developer is no longer available and cannot help with Knowledge Transfer. The original cost for development of the entire application was $400 We are not looking for a rebuild, but for a developer who can: Take over support and change requests Understand an existing codebase without hand-holding Make small, well-scoped enhancements The application: Built in Laravel Uses MySQL Hosted on Hostinger Integrated with Kajabi (purchase triggers account creation) Sends automated emails (reminders + assessment report) using Zoho Front-end website is WordPress (no WordPress dev required) Immediate task The first paid task that I am looking for quotes for is simply: Review the existing Laravel codebase Understand how Kajabi purchases trigger account creation Understand the email logic and assessment flow Confirm how a second product type can be added This initial task should result in: A short written summary of how the system works, how it's built, structured, technology being used, how the parts integrate A clear estimate for implementing the next change Upcoming change request We want to add a second product on our website Same assessment Includes 60 minutes of coaching Different email sequence and texts after purchase Different text in generated assessment report Account flagged as “Assessment + Coaching” Required skills Strong experience with Laravel MySQL Experience working with existing/legacy code Comfortable with webhook-based integrations (Kajabi or similar) Clear written communication in English Ability to explain technical concepts to non-technical clients Nice to have Experience with Kajabi Email automation / transactional email experience WordPress familiarity (not essential) I need your best fixed price quote for the first piece of work (taking over the codebase and writing up a report of how it works) along with giving a quote for the change request itself (which I expect once the code is understood, should be a matter of 3-4 hours of work but that is for you to validate).

PHP/MySQL Website Audit + Fix Indexing Issues + Technical Review

I run a live booking platform built in PHP + MySQL. The site works, but before continuing development, I need an experienced PHP/MySQL developer to: 1️⃣ Audit the existing codebase This includes reviewing backend logic (booking flow, pricing logic, automated emails/notifications, database structure and customer/assessor workflow), not just the visible front-end code. Review the current structure Check logic behind the booking/payment flow Identify any messy or legacy code that may cause scaling issues Confirm what’s built properly and what will need rewriting or optimising 2️⃣ Fix Google indexing issues The site is live but many pages are not indexing. I need: Sitemap and canonical structure reviewed Validation of meta/indexing rules Confirmation pages + dynamic pages handled correctly Any no-index / crawl issues resolved 3️⃣ Document findings & next-step recommendations After the audit, I want: A short report (bullet points are fine) covering: What’s working What’s broken What should be improved What should be prioritised now vs later Rough cost/time estimate for carrying out recommended improvements Optional (only if quick): Fix any small bugs you find during the audit. Requirements Strong PHP + MySQL experience (not WordPress/PHP theme developers) Experience working with or improving existing codebases Understanding of best practices for automation, booking logic, or SaaS-style systems Good communication and ability to explain technical findings simply Budget £150–£250 for the audit. If the indexing fix is small/simple, include it. If it requires additional work, provide a separate quote after the audit. Further development may follow based on the findings. Timeline Ideally completed within 7–10 days. To Apply, Please Send: One example of a PHP/MySQL system you’ve worked on (booking or automation is ideal). Whether you’re available for continued work after the audit if needed. Your preferred working style: ▫ Fixed price ▫ Hourly rate with cap Goal I want clarity before scaling — not guesswork. This audit will help determine the next stages of development. This is already posted on another platform — I will shortlist based on best fit, not first response.
