01 / The challenge
Incoming requests had no single source of truth.
A website form alone does not create a sales process. The business still needs reliable storage, immediate notification and a clear way to manage every opportunity after submission.
Delayed response
Important requests could remain unnoticed until somebody manually checked the inbox.
No consistent lead pipeline
Status, priority and final outcome were not managed through one structured workflow.
02 / The system
One connected workflow from form to follow-up.
LeadFlow separates the public experience, server-side logic, persistent storage, administration and notifications into focused components.
Customer details and project requirements are collected through the Nexivize website.
Requests are validated, normalized and protected through server-side rules.
Every accepted lead is stored with status, priority, source and timestamps.
The administrator searches, filters and moves leads through the sales pipeline.
Email and Telegram alerts are delivered automatically after a successful submission.
03 / Product capabilities
Designed for real operation, not a visual demo.
The system includes the production concerns required to receive and manage actual customer data.
Strict validation
Client-side guidance is backed by server-side validation for names, email addresses, phone numbers, companies and project descriptions.
Protected administration
JWT authentication protects private lead data and management operations from public access.
Searchable pipeline
Leads can be searched and filtered by status or priority, then updated as the opportunity progresses.
Spam resistance
A hidden honeypot, request limits and strict input handling reduce automated and malformed submissions.
Independent notification channels
Email and Telegram delivery are isolated from one another so a temporary provider failure does not prevent the lead from being stored.
04 / Outcome
A complete production workflow in one product.
LeadFlow demonstrates how Nexivize combines product design, frontend, backend, infrastructure and automation around a real business need.
