Looking for senior developer to upgrade my website quickly

My Laravel-based site needs two urgent tweaks on the checkout page. First, the mobile layout is misbehaving—buttons shift, fields overlap, and the overall flow feels clunky. I want the page to render perfectly on iOS Safari and Android Chrome while keeping the look identical to the rest of the site; please follow the existing design, no redesigns.

Second, I’m adding an ACH payment option to cut down on card declines. You’ll extend the current gateway integration (or recommend a compatible one) so customers can choose ACH, complete the flow, and receive the usual success or failure callbacks.

I’m ready to give you Git or FTP access the moment we agree, and I need a fast turnaround—only bid if you can start immediately and meet the deadline you quote.

Deliverables
• Responsive, bug-free payment page that matches my present styling.
• ACH option fully integrated, tested in sandbox and live modes.
• Short deployment or pull-request notes so I can merge without surprises.

I’ll mark the job complete when the page looks flawless on common phones and a test ACH transaction settles correctly. Let me know your exact timeframe and cost in your proposal; speed and accuracy are both critical.
