Custom CRM with Two-Way Data Sync

Custom CRM with Two-Way Data Sync
A custom CRM built to fit how a team actually works — and, crucially, kept in continuous two-way sync with the tools they already rely on, so data never has to be copied by hand or falls out of date in one place.
What it does
A full CRM — contacts, pipeline, activity — tailored to the team's workflow.
Two-way sync with email and existing business platforms.
Custom objects and views for data a generic CRM can't model.
Import tooling to bring existing data in cleanly.
How I approached it
Two-way sync is deceptively hard: without careful conflict handling, records fight each other and drift apart. I built the sync layer to keep both systems consistent, so a change in either place shows up correctly in the other — without creating duplicates or overwrites.
Why it matters
Teams outgrow off-the-shelf CRMs but dread the migration and the double data-entry. A custom CRM that syncs both ways with what they already use gives them a tool that fits — without abandoning the systems around it.
