PROJECT OVERVIEW

Project Overview

CLIENT

B2B Enterprise Platform

TIMELINE

20 weeks

ROLE

Full-Stack Architect

Sales teams were juggling spreadsheets, disconnected tools, and manual follow-ups. I built a unified CRM that brings leads, deals, campaigns, and team collaboration into one platform - with AI-powered insights to help reps focus on the deals most likely to close.

THE CHALLENGE

The Challenge

Feature Scope

The business needed a single platform covering contacts, deals, campaigns, analytics, and team collaboration - not five separate tools stitched together.

Real-Time

Multiple sales reps work the same pipeline simultaneously - everyone needs to see changes instantly to avoid stepping on each other.

Security

Enterprise clients require two-factor authentication, role-based permissions, full audit logs, and encrypted data storage.

Performance

Searching and filtering across millions of contacts and deals must feel instant - slow load times kill sales productivity.

THE SOLUTION

The Solution

A complete CRM platform where sales teams manage their entire customer lifecycle - from first touch to closed deal - with AI insights, campaign automation, and real-time team collaboration built in.

PIPELINES

Visual Sales Pipelines

Drag-and-drop deal management with custom stages, win probability scoring, and revenue forecasting so leadership always knows the pipeline health.

AI_INSIGHTS

AI-Powered Sales Intelligence

Automatic lead scoring tells reps which prospects to call first, deal prediction highlights at-risk opportunities, and next-best-action suggestions guide follow-ups.

CAMPAIGNS

Campaign Automation

Run multi-channel campaigns with email sequences, A/B testing, and conversion tracking - all from within the CRM, no separate marketing tool needed.

REALTIME

Live Team Collaboration

Everyone sees deal updates, team activity, and notifications the moment they happen - no more stale data or conflicting updates.
