Turn Your Prototype Into a Production AI SaaS
You've validated the idea with a prototype. Now you need a real product - built with production-grade code, scalable architecture, and AI that actually works. I'll take you from prototype to a fully functional AI SaaS product ready for marketing validation or investor pitch.
From Prototype to Product
Everything you need to go from prototype to a real AI SaaS product - starting at $5,000
AI SaaS Product Development
Get a fully functional AI product built with production-grade code - not a prototype, not a demo. Real architecture that handles real users and scales with your business.
- Production-ready AI features (LLMs, RAG, agents)
- Scalable backend & clean API design
- User authentication, billing & dashboards
- Deployment to production infrastructure
Prototype to Production
You've built something in Lovable, Bolt, or another tool that proves the concept. I'll rebuild it as a real SaaS product with proper architecture, database design, and code you can maintain and grow.
- No-code/AI prototype → production codebase
- Database design & data migration
- Third-party integrations (Stripe, APIs, etc.)
- CI/CD pipeline & cloud deployment
Technical Partnership
Need more than a one-off build? I can become your long-term technical partner - owning the product roadmap, making architecture decisions, and scaling the product as you grow.
- Ongoing CTO-level technical guidance
- Product roadmap & architecture ownership
- Team building & hiring support
- Equity or retainer arrangements available
From First Call to Launch
A clear, structured process so you always know what's happening and what's next.
Discovery Call
We hop on a free 30-minute call. You walk me through your prototype, your vision, and your timeline. I ask the hard questions so nothing gets missed.
Scope & Proposal
Within 48 hours, you get a clear scope document with features, architecture plan, timeline, and a fixed price. No surprises.
Build & Ship
I build in weekly sprints with a live demo every Friday. You see real progress every week and can steer direction as we go.
Launch & Handoff
Your product goes live with documentation, deployment pipeline, and a clean codebase. I stick around for 2 weeks post-launch to squash any bugs - with the option for ongoing support through a retainer.

About Me
I'm Nikola, a Senior Software & AI Engineer who specializes in one thing: turning early-stage AI ideas into real SaaS products. If you've built a prototype in Lovable, Bolt, or any other tool and need someone to make it production-ready - that's exactly what I do.
With a Master's degree in Intelligent Systems and experience shipping products at companies like SugarCRM and multiple startups, I've taken dozens of ideas from "it works in a demo" to "it's handling paying users." I understand both the technical challenges and the business pressure founders face.
Why Work With Me?
- Founder Mindset: I've been in the trenches with early-stage startups. I move fast, ship weekly, and make pragmatic tradeoffs.
- Full Product Ownership: I don't just write code - I own the technical decisions, architecture, and delivery. You focus on customers.
- Built for Growth: The product I deliver is designed to scale. When you're ready for your next 1,000 users, the code won't hold you back.
- Partnership Option: Start with a project, and if we're a good fit, I can become your long-term technical partner or fractional CTO.
