You will get Expert WhatsApp Cloud API (Meta) Integration with Node.js or Next.js

Project details
Stop paying monthly fees for third-party WhatsApp tools. Own your infrastructure.
I build custom WhatsApp Cloud API solutions integrated directly into your Next.js or Node.js stack — whether you need automated
notifications, AI-powered customer support, bulk campaigns, or CRM sync.
PROOF I CAN BUILD THIS:
I built flexgrew.cloud — a production WhatsApp SaaS platform with bulk campaigns, AI chatbots, automation flows, and multi-tenant architecture. Not a portfolio mockup. A live, running product.
WHAT YOU GET:
• Official Meta WhatsApp Cloud API setup (no third-party tools)
• Webhook integration with HMAC signature verification
• AI replies via OpenAI for natural customer conversations
• Bulk campaigns with queue management and delivery tracking
• Your data in your database (PostgreSQL or MongoDB) — you own it
• Production deployment on AWS, GCP, or Vercel with CI/CD
WHY CLIENTS HIRE ME:
12+ years building backends. 1,040+ Upwork hours. One client kept me on weekly for 2 straight years. Multiple 5-star reviews.
Send me a message with what you're building — I'll respond within a few hours with a clear next step.

About Daksh
Senior Laravel & PHP Developer | API, SaaS & CRM Backend | 12+ Yrs
Rajkot, India - 5:50 am local time
One of my Upwork clients kept me on a weekly basis for 2 straight years (720+ hours).Another scaled their CodeIgniter platform with me across 200+ hours. That's the kind of work I do best: becoming the developer a business trusts to ship, fix, and scale — not just deliver one project and disappear.
WHAT I BUILD:
- Laravel & PHP backends — REST APIs, admin panels, business logic
- SaaS platforms — multi-tenant architecture, billing, user systems
- CRM customization — Perfex, custom modules, third-party integrations
- Legacy PHP modernization — 5.x → 8.x upgrades, security patches
- Node.js / Next.js / Nuxt frontends when the project needs full-stack
RECENT CLIENT FEEDBACK:
★ "Dax does a great job and cares about what I want and making sure it is correct. (2-year retainer client)
★ "Very experienced and knowledgeable — really helping us reach our goals." (CMS project)
★ "Dax is a very reliable person." (CodeIgniter 4, 201 hours)
HOW I WORK:
- Clear daily updates — you always know where the project stands
- I ask questions before writing code, not after breaking things
- Available across US and EU hours for calls and quick fixes
- I write code other developers can read 6 months later
If you need someone who will actually own the backend of your product — not just close tickets — let's talk. Send a message with what you're building and I'll respond within a few hours.
Steps for completing your project
After purchasing the project, send requirements so Daksh can start the project.
Delivery time starts when Daksh receives requirements from you.
Daksh works on your project following the steps below.
Revisions may occur after the delivery date.
Meta Business Setup & Secure Webhook Integration
I'll configure your Meta Developer App and WhatsApp Business Account (WABA). Then I'll establish a verified webhook with signature validation on your Node.js or Next.js server for reliable real-time message delivery.
Backend Architecture & Message Flow Logic
I'll design a PostgreSQL or MongoDB schema to log chats, contacts, and message statuses. Then I'll build the core logic for interactive buttons, list menus, and automated media handling (images, PDFs, documents).
