Industry
SAAS
Full-stack development for B2B SaaS startups. From MVP to scale, with multi-tenant architecture and API design as core competencies.
I work seamlessly with Seoul and KST timezone teams. Also available in nearby cities: Incheon, Suwon.
Why SaaS
SaaS apps need technical foundations that support growth and monetization:
- Multi-tenant architecture: complete data isolation between tenants
- Scalable API design: optimized GraphQL or REST
- Authn / authz (SSO, SAML, OAuth, role-based access)
- Rapid MVP launch and continuous delivery
Approach
Development principles I apply to SaaS projects:
- Type safety: robust codebase with TypeScript
- API-first: type generation and testing from OpenAPI specs
- Infra as Code: optimal Vercel, Supabase, and Firebase combinations
- Monitoring: error tracking, performance, and user analytics
