About this gig

Need a SaaS built fast, without the mess that usually comes with "fast"?


I'm a senior full-stack engineer with 7+ years building software for US and international companies. I use AI tools (Claude Code, Cursor) to speed up development, and senior-level review to keep your code secure, tested and ready to scale.


What you get:

  • A working SaaS MVP, deployed and ready for real users
  • User authentication and account management
  • Subscription billing with Stripe
  • Admin panel and core business features
  • Third-party API integrations
  • Clean, documented code that you fully own


Stack: Laravel, NestJS/Node.js, TypeScript, Angular, PostgreSQL, Redis, AWS, Docker.


Why me:

  • Real production experience in fintech, payments and SSO
  • AI speeds me up; it doesn't replace engineering judgment
  • Clear scope up front, frequent updates, no surprises



Please message me before ordering so we can define scope and timeline together. Tell me what you're building!
