Saad FazalBackend & automation developer
LD-2026All areas
Hi, I'm Saad.
Shopify apps, Meta developer apps like Accurate Profit, WhatsApp on Cloud API, GHL (flows, agents, funnels, email), and ElevenLabs / retail voice agents. Client delivery for Disruptive Brain and Flaxen Media; EasyCloudAPI is my own.
The work I get called for is usually the part with no documented path - a reorder flow Shopify does not support, ads profit that has to join three APIs, a voice line that must book into GHL, or a queue that has to hold at 2am.

Five systems, numbered in the order I would walk you through them. Each one starts with the problem and ends with what shipped.
All 12 projects01 / Content
02 / AutomationCodeBuddy
My personal WhatsApp coding buddy - allowlisted numbers, model switching, and /ask in groups so it doesn’t spam.
03 / ProductAccurate Profit
Meta developer app with a full dashboard - connected Shopify stores to Meta (Facebook) Ads and Google Ads so profit and ad spend stay in one place.
04 / ProductEasyCloudAPI
Multi-tenant WhatsApp Business platform on Meta Cloud API: team inbox, campaigns, AI agents, automations, and Shopify order updates.
05 / ShopifyShopify apps & backend
Custom Shopify apps and Node/Express backends for merchants - including Vulgrco’s custom product reorder flow that Shopify does not support natively.How I work
What I do before writing the schema
Find out what actually breaks
Before I design a schema I want the failure cases: the webhook that arrives twice, the token that expires at 2am, the merchant with 400 variants. Those decide the shape far more than the happy path does.
Keep the slow work off the request path
Webhooks get a fast acknowledgement and a queue. Meta gets its 200 in milliseconds, the worker takes as long as it needs, and a retry is a normal event rather than an incident.
Build the ops surface, not just the endpoint
An integration nobody can inspect becomes someone's 3am problem. Inbox, logs, usage, manual retry - the boring screens are what make a system supportable after handover.
Hand it over so it survives me
Config over hardcoding, error paths that say what went wrong, and a merchant or ops person who can run it without opening a terminal.

Got a messy problem to ship?
I'm strongest when the work spans backend, integrations and the product surface - Shopify, Meta apps, WhatsApp, GHL, voice agents, or retrieval that has to cite sources.
