Working Notes
Real-world learnings from building and operating lending and debt collection platforms. This pillar documents what actually works in production, what breaks under pressure, and the patterns that emerge when you build these systems at scale.
Captures the messy reality of building financial systems. These aren't polished case studies but active documentation of what we're learning as we build. You'll find notes on production incidents, architectural decisions that worked (and ones that didn't), and the kind of operational knowledge that only comes from running systems in the real world.
Topics here range from payment processing quirks to loan servicing workflows, from collections automation to reconciliation nightmares. If it's something we've encountered while building debt-collections (and fintech systems in general), it belongs here.
