Why Build Custom Instead of Buying Off-the-Shelf?
Salesforce costs $150/user/month and still doesn't do what you need. Monday.com looks pretty in demos but breaks when your workflow has actual complexity. You're paying for features you don't use and missing the ones that matter.
A custom SaaS platform costs less than two years of enterprise subscriptions and does exactly what your business needs. No compromises, no workarounds, no "we'll add that in our next roadmap update."
I've built complete business platforms — CRM, estimating, quality control, field operations, device monitoring — that replaced spreadsheet chaos with structured, AI-enhanced systems. Every one of them was delivered in under 12 weeks. Every one of them is still running in production.

How a Custom SaaS Build Works
Week 1: Specification
We define exactly what you need. I produce a technical specification document with every feature, data model, and user flow documented. You review and confirm. No ambiguity, no scope creep.
Weeks 2-6: Build
Database design, backend API, frontend interface, AI integration, third-party connections. Weekly updates with working demos. You see progress in real-time, not after months of silence.
Weeks 6-8: Production
Deployment to production infrastructure, data migration, team onboarding, final testing. Your team starts using the system. I stay available for hot fixes and rapid iterations.
Ongoing: Maintenance & Evolution
Production systems need ongoing care. I offer maintenance retainers — updates, feature additions, performance optimization, and support. Your platform grows with your business.
Questions About SaaS Development
How long does it take to build a custom SaaS platform?
4-12 weeks depending on complexity. Simple platforms with 10-15 features ship in 4-6 weeks. Enterprise platforms with 40+ data models, AI integration, and multiple user roles take 8-12 weeks.
How much does custom SaaS development cost?
My rate is $90/hour. Typical platforms run $15,000-$50,000. Complex enterprise platforms with AI can reach $50,000-$100,000. Agencies charge $150,000-$500,000 for equivalent systems.
What tech stack do you use?
Next.js 14 + React + TypeScript frontend, Node.js or Python (FastAPI) backend, PostgreSQL with Prisma, AWS or Vercel hosting. Authentication via NextAuth.js/Clerk. Payments via Stripe. AI via Claude and GPT-4.
Can you build multi-tenant SaaS?
Yes. Multi-tenant architecture is standard. Database-level tenant isolation, role-based access, organization management, per-tenant configuration. I've built platforms handling 500+ organizations with strict data boundaries.
Do I own the code?
Ownership depends on the engagement model. For fixed-price projects, you typically own the code upon final payment. For ongoing retainer work, ownership is defined in our agreement. Everything is transparent and agreed upfront.
