From Broken Demo to 10K Users
The Situation
A startup had a "working" AI feature that crashed with real users. Hallucination rate was 35%. They needed it fixed before their launch event.
The Approach
Rewrote the AI layer: proper context window management, output validation, fallback logic. Added monitoring to catch issues before users.
"Fixed price, shipped on time, code that my team actually understands. First freelance hire where I did not have to micromanage."
— Lisa Nakamura, Product Owner at HealthStack
What You Get
How It Works
Understand your problem
30-minute call. Not to sell — to understand. I ask hard questions about scope, constraints, and what "success" looks like.
Fixed-price proposal
You get a detailed scope and price in 24 hours. No hourly estimates. No surprises. Price holds unless scope changes.
Build with visibility
Weekly demos. You see working code every week. Not a demo at the end, but progress you can test and validate.
Transfer & support
Clean code, documentation, and 30 days of support included. You own everything. No lock-in.
Ready to Get Started?
Book a free 15-minute call to discuss your project. No commitment, no sales pitch — just an honest conversation about what you need.
Common Questions
How available are you for calls?
I block 2-3 hours daily for client calls. Most clients do a weekly sync plus async Slack/email. For urgent issues, I respond within a few hours. Timezone: CET (Madrid).
What if you get sick or unavailable?
I have never missed a deadline due to illness, but it happens. I have trusted peers who can step in for critical issues. I also document everything so someone else can continue.
How do you handle project management?
I use Linear, Notion, or whatever you prefer. Weekly progress updates with demos. I manage the technical work; you focus on your business.
What do you not work on?
I do not work on anything illegal, deceptive, or harmful. I avoid projects where AI safety is an afterthought. If your use case raises ethical questions, I will discuss them upfront.
