Day 22: import batches are visible in the CLI.

Batch 1 → 3 leads. Bad ID 999 → no crash.

Gap: new timestamp still clones Jane (ID 11, now also 14). History ≠ lock.

#Python #SQLite #BuildInPublic

[Omowaye Joshua Oluwaseun @CtrlSEUN]

Day 21: same cleanup batch can’t import twice.

First: 3 in. Replay: 0 in, 3 skipped. Still 3 leads.

Lock is the batch key, not “email unique.”

Gap: new timestamp = new batch. Same CSV tomorrow can clone Jane.

#Python #SQLite #BuildInPublic

Day 20: CLEAN rows finally hit SQLite.

3 imported. Status NEW. CREATED activity. CLI sees them.

Broke: python -m app.crm_cli → missing error_handler / database. Needed app. imports.

Gap: run twice = duplicate leads. Skip-by-email is Day 21.

#Python #SQLite #BuildInPublic

Day 19: each cleanup gets its own folder.

output/Client/cleanup_timestamp/
CSV opens first. Missing file = error, no empty folder.

6 files per run. Clients don’t mix.

CLEAN still isn’t in SQLite.

@DataSynthGen Thanks! Honestly, the biggest surprise was how fast small issues tank the score. A few missing fields and duplicate groups can drag down CRM health quickly.

It made me realize data cleaning isn’t just about fixing errors it’s about making the database trustworthy for the team

Day 18: CRM health score.

Validity 40 / uniqueness 35 / completeness 25.

Messy file → 81% GOOD. Clean file → 100%. Empty/missing CSV errors.

Dupes = groups, not pairs÷2.

#Python #DataQuality #BuildInPublic

Day 17: fuzzy duplicates. RapidFuzz, not “AI.”
Same name ≠ same customer.

John Adewale vs Jon Adewale: name 95%, company 86%, email 76%, phone 43% → POSSIBLE DUPLICATE, not merge.

HIGH = same email/phone. MEDIUM = human review. No auto-delete
#Python #RapidFuzz #BuildInPublic

[Omowaye Joshua Oluwaseun @CtrlSEUN]

Day 16: bulk CRM cleanup.

7-row CSV → 3 CLEAN / 2 REVIEW / 2 DUPLICATE.

Same email+phone = dupe. Flagged, not deleted.

0803… → [phone]. Original kept.

Dirty in. Three files out. DB stays clean.

#Python #CSV #BuildInPublic

[Omowaye Joshua Oluwaseun @CtrlSEUN]

Day 15: status changes now write history.

Before: overwrite the column. Old value gone. Now: save old → new, then update.

CLI kept CONVERTED → LOST. Dashboard un-counted it.

Snapshot ≠ audit trail

Next: first outreach auto NEW → CONTACTED

#Python #SQLite #BuildInPublic

[Omowaye Joshua Oluwaseun @CtrlSEUN]

Day 14: added status to a live SQLite CRM without wiping data.

PRAGMA, then ALTER only if missing. Started lead_activities

CONTACTED → CONVERTED. 1/7 = 14.29%.
Status = snapshot. History = audit trail.

Next: first outreach auto NEW → CONTACTED.
#Python #SQLite #BuildInPublic

[Omowaye Joshua Oluwaseun @CtrlSEUN]

Day 13 — My CRM dashboard said I converted 100% of leads.

But status breakdown said: CONVERTED: 0.

The bug? One SQL query was counting every lead.

Fixed it with the correct WHERE status = 'CONVERTED'.

Lesson: metrics are only as honest as the SQL behind them.
