One system for a collections agency's whole day: the accounts, the outreach, the payments and the paperwork. I designed and built it end to end.

What I designed:

• A visual workflow builder, a custom canvas built from scratch. Triggers, waits, branches, email, SMS, AI voice calls and collector tasks connect on one screen, so operations staff can change a follow-up sequence without a developer.

• A manager dashboard: the monthly collection goal, cleared and post-dated payments, team performance, plans at risk and review queues.

• A financial command center: a time-layered P&L from today through year to date.

• An e-sign tracker with a verification view for every document: tamper check, event timeline, signing forensics and a public verification link.

What runs behind it: 36 scheduled jobs handle the work nobody should do by hand, from sending campaigns and texts to warming up email domains, running payments and retrying declines, executing workflows every minute and keeping the AI dialer moving.
