SyncFlow (WhatsApp Profile Sync)

Operational teams and agencies waste hours manually copy-pasting candidate details and document attachments from WhatsApp chats into CRMs and compliance databases — introducing compliance risks and manual data entry errors.

Designed and built a self-hosted, entity-agnostic connector with template parsing, allowlisted sender checks, in-memory event tracing, and a local mock simulation dashboard.

A deterministic template-driven webhook server that parses key-value formats from allowlisted numbers, stores credentials securely, and syncs profiles to local databases or forwards them via custom HTTP API multi-part uploads.

A lightweight Node.js HTTP webhook server that processes incoming Meta Cloud API payloads on the fly, coupled with an in-memory event log and local disk storage driver for mock data and downloads.

• Allowing developers to demo and test the full Meta webhook flow without creating Facebook Developer accounts (resolved via the in-browser simulator)
• Normalizing international phone numbers dynamically to guarantee find-or-create updates
• Routing attachments to target profile sub-folders safely without path traversal vulnerabilities

• Designed and implemented the core webhook parser and sync lifecycle
• Created the events registry and mock media interceptor to bypass Graph API for simulator usage
• Built the glassmorphic simulator UI and database explorer end-to-end

• Config-driven templates (e.g. Worker, Lead, Profile) avoiding codebase forks
• Caption-based media slot parsing (e.g. photo, resume, certificate) for secure file routing
• Interactive mock simulation dashboard with a virtual WhatsApp chat simulator
• HMAC signature checking and E.164 phone allowlist filters for enterprise security

• Local testing simulators turn complex webhook integrations into interactive sales demos that close deals.
• Making compliance systems self-contained and config-driven eliminates custom code sprawl.
