AI SaaS Engineer

I engineer AI products, not automations.

I started as a software engineer, writing production code for growing companies. Over time, I focused on what founders actually need: AI products that scale, architectures that hold up, and software that businesses rely on.

That's what I do now. I help founders and businesses design, build, and launch production-ready AI SaaS products with modern engineering practices, from MVP to production.

01

Discovery

Free · 30 minutes

We map your product requirements, technical constraints, and business goals. You leave with a clear architecture plan and realistic timeline. No pitch, no commitment.

02

Architecture & Build

4–8 weeks for MVP

I design and build your AI product from scratch, engineered for scale from day one. Modern stack, clean architecture, working prototypes throughout. You see progress every week.

03

Launch & Support

Done for you

We deploy to production, run end-to-end testing, and hand off with complete documentation. I stay available for the first 30 days to handle tuning and edge cases. Most products run smoothly within days.

Why Work With Me

Production-ready architectures

Everything I build is engineered for real-world scale, not demos. Clean code, proper error handling, monitoring, and documentation from the start.

AI systems that work reliably

Structured outputs, fallback handling, input validation, and comprehensive testing. Production AI needs to work when data varies and edge cases arise.

Senior-level technical thinking

Fast communication, clear architecture decisions, and pragmatic trade-offs. You work directly with the engineer building your product, no account managers.

The discovery call is free. Most founders find it useful even if they don't hire me.
