Sadik B.

"Sadik is the single best freelance resource I've ever used on any project." - Upwork client

I build the membership platforms, custom web apps, and high-traffic sites that other developers can't finish. Senior Full-Stack PHP & WordPress developer, 12+ years. Top Rated Plus, 100% Job Success across 114 jobs, 10,026 hours billed, and $500K+ earned on Upwork.

I specialize in long-running, complex engagements, not quick fixes. My flagship is a 5+ year build of a custom PHP/MariaDB supply-chain ERP (2,700+ hours, sole architect): inventory, shipments, batch lifecycle tracking, and a cron-based background processing layer.

🌟What I deliver:

• Membership & subscription platforms (Paid Membership Pro, MemberPress) with Stripe/PayPal recurring billing
• Custom PHP business applications & ERP systems built from the ground up
• Large-scale CMS & forum migrations (vBulletin to XenForo, Joomla to WordPress, cross-database consolidation)
• WordPress performance rescue: database, hosting, and query optimization on Kinsta/VPS
• Custom WordPress plugins, themes, and CRM/API integrations

🌟Recent client wins:

• Cut a 12-second page load to normal by fixing an unindexed query; reduced WordPress autoloaded options from 17.7MB to 0.6MB
• Built and ran a membership platform for an Australian investor community with recurring subscription revenue
• Architected a $150K+ custom ERP processing inventory, shipments, and batch lifecycles
• Cleaned 979K form entries and 7.8M meta rows to dramatically reduce database load
• Migrated multiple legacy forums to XenForo with zero data loss

🌟Perfect for:

Founders running membership/subscription sites, businesses needing a custom internal platform or ERP, and site owners with a WordPress performance or migration problem nobody else can solve.

🌟Why clients keep me for years:

I hold multiple 4-5 year ongoing retainers because I communicate clearly, deliver on schedule, and understand the real business behind the spec. As one client put it, "incredibly pro-active and accurate."

Send me your project or pain point and I'll reply with a clear assessment and realistic roadmap. Available for complex builds, rescue projects, and long-term partnerships.
