Meta Tech Provider specializing in WhatsApp Business API, Facebook Conversions API (CAPI), Meta Pixel, and CRM integrations. Most Meta integrations fail quietly. A webhook stops firing, App Review gets rejected for the third time, Facebook CAPI events show up in Events Manager but never match, or a WhatsApp number gets restricted the week you launch. I fix those problems, and I build things so they don't happen in the first place. My work sits where engineering meets marketing: WhatsApp Cloud API, Meta Graph API, Facebook Marketing API, Conversions API, and the CRMs and automation tools that tie them together. I'm a full-time freelance developer based in Karachi, Pakistan, working directly with founders, agencies, and marketing teams. WHATSAPP BUSINESS API & MESSAGING - Embedded Signup and multi-tenant onboarding for WA, Instagram, and Messenger via Meta OAuth - WA Cloud API builds: webhooks, message templates, inbound and outbound flows, chatbot logic, and AI lead qualification - WA voice calling routed into contact-center platforms such as Genesys Cloud - BSP setup and migration: 360dialog, Wati, YCloud, and Twilio ISV sender registration - Compliance guidance on opt-in, template approval, quality rating, and messaging limits - Account restrictions, bans, and reinstatement appeals META APP REVIEW & BUSINESS VERIFICATION - App Review submissions, including permission justifications, screencasts, and use-case write-ups - Debugging Standard vs. Advanced Access gaps and missing permissions that silently break webhooks - Business verification and Tech Provider onboarding for SaaS platforms FACEBOOK CONVERSIONS API & TRACKING - Server-side CAPI, Pixel and CAPI deduplication, Advanced Matching, and event match quality - CAPI audits and builds for Shopify, Webflow, and HubSpot-Zapier-Meta pipelines - Lead-quality feedback loops that send CRM stage changes back to Meta and Snapchat, so campaigns optimize for real customers instead of raw form fills - Mobile app install attribution fixes and tracking clean-up before you scale ad spend META MONETIZATION & COMMERCE - Content Monetization recovery: connected-entity violations, business verification, and payout account remediation - Facebook Page analytics and earnings dashboards for publishers - Commerce Manager catalog troubleshooting, including feed sync and localization issues CRM INTEGRATIONS & AUTOMATION - CRMs: HubSpot, Zoho, GoHighLevel, Close - Automation: Make, n8n, Zapier, and custom - Custom Node.js and TypeScript backends, webhook infrastructure on Upstash Redis and Vercel serverless, and documented Postman collections for the Meta and Instagram Graph API so your team can keep building after I'm done EXAMPLES OF MY WORK - A multi-tenant SaaS that routes WA voice calls into a contact-center platform through the Meta Cloud API - A WA Business SaaS with a CRM panel and a visual chatbot builder - Meta OAuth onboarding for WA, Instagram, and Messenger in a Node.js and TypeScript app - A lead-quality CAPI setup sending Webflow and Zoho CRM data to Meta and Snapchat - Install-attribution fixes for a mobile app, followed by campaign scaling - Meta app permission approvals for client apps and lead access WHO I WORK WITH - SaaS founders building on top of WhatsApp, Instagram, or Messenger - Marketing agencies managing Meta assets for multiple clients - E-commerce brands that need trustworthy ad attribution - Publishers and creators dealing with Meta monetization issues - Businesses that need a reliable BSP or Cloud API setup without the guesswork HOW I WORK - I diagnose before I build. Many "broken integration" jobs turn out to be a permission, verification, or configuration issue, and I'll tell you that upfront rather than bill you for a rebuild you don't need. - I scope the work clearly and flag risks such as Meta review timelines, API limits, and policy constraints before we start, so there are no surprises mid-project. - You get clear written updates, documented handoffs, and code you can maintain. - I'm honest about what Meta allows and what it doesn't. If a request puts your account at risk, I'll say so before we start. GOOD FIT IF YOU NEED - A WhatsApp integration built or rescued - Your Meta app approved - Your ad tracking fixed so the data can actually be trusted - A CRM connected to Meta properly - A developer who knows Meta's platform from the inside Send me a message with what you're working on, where it's stuck, and any error messages or screenshots you have. I'll tell you plainly whether I can help and what the fastest path looks like. Let's get your Meta stack working the way it should.
