Visual IDE for Complex Credit Decisions

Built for analysts, ops, and risk teams to model and manage credit decision logic — without writing code.
I designed a flexible, consistent interface for building workflows, inspecting errors, and configuring details across 250+ screens — including the IDE, admin, GIT, and more.

📈 Impact

🧠 Non-dev teams built and maintained complex decision flows end-to-end
Workflow creation time dropped from 1.5 days to a few hours
📉 -60% engineering requests for routine config changes
🌟 4.7 out of 5 user satisfaction from internal teams

💡 Key Wins

✔️ Fully consistent across 250+ screens
✔️ Clear structure in dense flows — no lost context
✔️ Icon system of 170+ shapes, readable at small sizes

🛠️ My Role

I designed the entire UI — from workflows to config panels.
My focus: clarity in logic, real-time feedback, and consistency across 250+ screens.
Worked side by side with PMs, analysts, and engineers to turn complexity into simplicity.

💪 Challenges

Complex logic — non-devs needed to manage advanced workflows
Error handling — system had to guide users through fixes
Information overload — too many options, not enough structure
Scalability — workflows ranged from 5 to 200+ nodes
Visual consistency — 250+ screens, dozens of modules and tools

Interface Elements

We built a flexible component system to keep the UI consistent across 250+ screens — from icons and filters to full-page flows
