My store is running on the stock OpenCart theme and I want to keep it that way; no third-party templates are needed. What I do need is targeted, code-level help in three areas: • Razorpay payment gateway set-up and testing so every transaction—regular, subscription, refund—flows cleanly from checkout to settlement without breaking the core files. • SEO polishing: keyword-driven titles, meta descriptions, and schema updates plus tangible speed gains (Core Web Vitals or GTmetrix improvements are the yardstick). • Light layout tweaks inside the default theme—think cleaner product pages, clearer call-to-action buttons, and a more intuitive header/footer—done with overrides so future OpenCart updates remain painless. I will provide admin access, Razorpay keys, and current keyword research. The work is complete when a test payment clears, pages pass basic SEO audits, and site speed shows a measurable boost.
