Travel Tech SaaS and Mobility Intelligence

VisaPath

AI-powered visa strategy optimization for digital nomads, frequent travelers and expats.

VisaPath is live as a modern B2C SaaS platform helping users optimize global mobility decisions across citizenships. It combines access mapping, AI route optimization and embassy intelligence so travelers can plan smarter, reduce friction and move with confidence.

Challenge

Users with one or more passports struggled to compare visa access, optimize multi-country plans and manage embassy logistics in a single reliable workflow.

Solution

We built a full-stack travel intelligence SaaS with premium glassmorphism UX, Supabase-secured account architecture, and an AI engine that computes optimized routes with practical cost and transport guidance.

Tech Stack and Architecture

Frontend and Product Experience

• Next.js App Router with SSR-ready SaaS architecture
• Tailwind CSS, Radix UI and Framer Motion for premium UX
• MapTiler SDK for interactive global access and path maps
• Lucide iconography and component-driven UI system

Data, Auth and Security

• Supabase PostgreSQL with profiles and user_passports schema
• Strict Row Level Security isolating each user data scope
• Production-safe Supabase auth across account flows
• Pro-tier gating with API-level edge rate-limiting rules

AI and Optimization Engine

• Llama 3 via Groq API for route optimization logic
• Constraint-aware itinerary generation for multi-country travel
• Integrated visa-cost, transport and route tradeoff outputs

Engineering Phases

Phase 1: Core Platform and Identity Layer

Built the secure account foundation with Supabase auth and user profile schemas, including support for multi-passport identity models.

Phase 2: Global Access Intelligence

Implemented interactive global access mapping that computes destination eligibility across up to multiple citizenship combinations.

Phase 3: AI Route Optimizer

Delivered an AI trip planning engine that transforms destination constraints into mathematically optimized routes with cost and transport suggestions.

Phase 4: Monetization and Scale Controls

Introduced subscription-aware feature gating and API protections so Pro and Team capabilities stay performant and secure under growth.

Debugging Highlights

• Hardened RLS policies to guarantee strict per-user row isolation for passports and profiles.
• Stabilized map and route rendering paths for smooth multi-destination visualization.
• Enforced API-level rate limiting and plan checks to protect premium optimization endpoints.

Roadmap

• Expand embassy intelligence with richer real-time appointment signals.
• Add collaborative trip planning workflows for team and family accounts.
