🎓 WordPress LMS & Membership Website Developer 📚 LearnDash | Tutor LMS | WooCommerce | Membership Sites ⭐ 5.0 Star Client Ratings 💬 Clear Communication, Honest Timelines, Post-Launch Support Hi, I'm Showrab — a WordPress developer who builds e-learning websites, online course platforms, and membership sites that actually work for the students and members using them. If you've tried setting up an LMS website before, you already know the hard part isn't installing the plugin. It's making course progression behave, getting payments to unlock the right content automatically, and making sure a student never hits a locked page they already paid for. That's the work I specialize in. 𝐖𝐇𝐀𝐓 𝐈 𝐃𝐎 📚 LearnDash & Tutor LMS Development Complete LMS website setup — course structure, lessons, topics, quizzes, assignments, drip content, certificates, and student progress tracking. Whether you're launching your first online course or migrating an existing academy, I build it to scale. 🔐 Membership Website Development Tiered membership levels, content restriction, recurring subscriptions, and paid community access. Built with MemberPress, Paid Memberships Pro, or a custom WordPress membership setup depending on what your business actually needs. 🛒 WooCommerce & Payment Gateway Integration WooCommerce store setup connected to course enrollment, so access unlocks the moment payment clears. Stripe, PayPal, Razorpay, and other gateways configured, tested, and working — including subscriptions and one-time course purchases. 💬 Community & Forum Websites BuddyPress and bbPress community sites with forums, student groups, private discussions, and social profiles — fully integrated with your LMS and mobile-friendly. 🐞 WordPress Bug Fixes & LMS Troubleshooting Broken enrollment flows, payment gateway errors, course access permissions misbehaving, plugin conflicts. If your LMS website is half-finished or something stopped working after an update, send it my way. ⚡ WordPress Speed Optimization & Security Page speed optimization, caching setup, image and database cleanup, security hardening, and regular maintenance so your course site loads fast and stays safe. 🔄 Website Migration & Redesign Safe WordPress migration between hosts or domains with zero data loss, plus full redesigns for outdated sites that need to look current. 🎯 Landing Page Design Conversion-focused landing pages built to turn visitors into enrolled students — clean, fast, and mobile-responsive. 𝐑𝐄𝐂𝐄𝐍𝐓 𝐔𝐏𝐖𝐎𝐑𝐊 𝐏𝐑𝐎𝐉𝐄𝐂𝐓𝐒 ✅ WordPress Tutoring Functionality Website A long-running engagement building out tutoring functionality on WordPress across 47 hours. 5.0 rating, and the client endorsed me for Committed to Quality, Detail Oriented, and Accountable for Outcomes. ✅ WordPress E-Learning LMS Website Full LMS website built from scratch — course setup, student enrollment flow, and payment integration. ✅ LMS Website (in progress) 5.0 rating given mid-project. The client's words: very happy, recommends me to others looking for a web developer. 𝐖𝐇𝐘 𝐂𝐋𝐈𝐄𝐍𝐓𝐒 𝐖𝐎𝐑𝐊 𝐖𝐈𝐓𝐇 𝐌𝐄 🎯 I ask before I build Most LMS projects go sideways because nobody defined what happens when a student pays, or what each membership tier can actually see. I get that clear on day one. 💬 You won't have to chase me I reply within a few hours during my working day and send progress updates without being asked. 🧠 Plain language, not jargon I'll explain what I'm doing and why, in words that make sense. If something you've asked for is a bad idea, I'll tell you honestly — and suggest what to do instead. 🔧 I stay after launch Questions after handover get answered. I'm not the developer who disappears once the invoice clears. 𝐈’𝐌 𝐀 𝐆𝐎𝐎𝐃 𝐅𝐈𝐓 𝐈𝐅 𝐘𝐎𝐔 𝐍𝐄𝐄𝐃 - A LearnDash or Tutor LMS course website built properly the first time - A WordPress membership site with paid tiers and community access - An existing LMS fixed — broken enrollment, payment issues, or access bugs - WooCommerce connected to automatic course enrollment - A developer who explains things clearly and communicates on time Send me a message describing what you're trying to build.
