Radian Corporation — Location-Based Pricing & UX

A pricing experience that adapts to where the customer is. Rebuilt the quote flow around location-based pricing logic and an interface that explains the number, not just displays it.

InsuranceLocation PricingUX/UIDesign System
−38%quote time
+22%conversion
99.8%uptime
↗

Context

Radian priced everything the same way regardless of where the customer was — leaving accuracy and trust on the table in markets with real regional variance, and a quote flow that buried the reasoning behind the number.

What we built

A location-aware pricing engine tied to a redesigned quote UI — clearer breakdowns, fewer steps, and pricing logic that shows its work instead of just outputting a total.

Systec Cloud — Provisioning & Niche App Infrastructure

Our own platform: vendors register, we provision their infrastructure, and build the niche app that runs on it. One system behind every vendor we onboard.

InfrastructureMulti-TenantFly.ioProvisioning
<90sprovisioning
−87%devops hours
↗

Context

Every vendor we onboard needs its own infrastructure, its own niche app, and its own way of running it — doing that by hand doesn't scale past a handful of clients.

What we built

Systec Cloud: vendors register, describe what they need, and get provisioned infrastructure plus a purpose-built app running on it — the same idea-to-production pipeline we use for direct client builds, productized.

Shun Technologies — Real-Time Vendor Management

A real-time vendor management platform for supply chain operations. Live inventory visibility, ML-driven demand signals, and vendor coordination in a single interface.

Supply ChainMLChatbotWorkflows
−18%stockouts
−23%holding cost
↗

Context

Supply chain operations spread across disconnected tools — vendors, bottlers, and mounting operations each with their own systems. No single view of demand, inventory, or supplier status.

What we built

Unified vendor experience platform: a conversational interface for operations teams to query inventory, trigger workflows, and surface ML-driven demand signals. Bottler and mounting automation reduced manual coordination overhead significantly. Integrated directly with WMS and ERP systems.

UniTravel Tech — Travel Recommendations & Vendor Integration

A recommendation chatbot that pulls live availability from tour operators, hotels, and activity vendors across 12 LATAM markets — grounded in real inventory, not static listings.

TravelRAGChatbotVendor Integration
12markets integrated
<2sresponse time
↗

Context

Static listings don't capture what's actually available — tourism vendors update inventory constantly, and travelers want recommendations, not a wall of search results.

What we built

A RAG-backed recommendation chatbot pulling live availability from tour operators, hotels, and activity vendors — grounded answers instead of generic suggestions, integrated with each vendor's own booking system.
