B2B Safety Confirmation Platform Development
Cloud platform that lets enterprises check employee safety en masse during major disasters and gives administrators a holistic operational view. Feature development and maintenance.
Challenge
- Access surges during disasters require the system to handle spikes while staying low-cost during normal operation.
- Handling sensitive employee data (location, contact info) demands stringent security baselines.
- Notification channels (email / SMS / push) must be customizable per client enterprise.
Solution
- Adopted a serverless Hono + AWS Lambda architecture to absorb disaster spikes via auto-scaling.
- Configured RDS (PostgreSQL) Multi-AZ with encrypted backups and VPC isolation for confidentiality.
- Designed pluggable notification handlers (Strategy pattern) swappable per client.
- Built a Next.js admin dashboard with real-time aggregation cached via SWR.
Technology Decisions
Why Hono instead of Express
Cold-start time is one-third of Express, improving first-request response during disasters. TypeScript-first design provides strong type safety.
