Solo engineer · Fixed-price · 90-day ROI
I build systems that test themselves, fix themselves, and prove they work. Here's the evidence.
representative output from a live run — see Proof of Work
When you hire Pruweba, every system I deploy is tested, recoverable, and traceable by design. Here's what that means:
Every action tested before it goes live.
If it breaks, it fixes itself.
Every change logged and traceable.
Once built, the rules can't be bypassed.
I don't just consult. I deploy systems that run your operations — so you can focus on your business.
Pruweba is a solo engineering practice, not an agency network. Every engagement is led by Jan Michael Acibron, fixed-price, and scoped to a specific ops outcome.
[ABOUT]
Pruweba is a proof layer built on top of Jan Michael Acibron's 34-pillar operations governance framework. It turns operational controls into shipping systems: tested, recoverable, and traceable by design.
The practice is intentionally small. Fixed-price scope means no agency overhead, no junior handoffs, and no open-ended retainers.

[PIPELINE]
Shoppers are asking AI where to buy. If your schema and entities aren't readable, you're invisible before the sale ever starts.
Manual Shopify ↔ 3PL sync errors: duplicate orders, lost shipments, stock that's wrong the moment it's checked.
Supplier and carrier overcharges that sit unnoticed in invoices no one has time to line-by-line audit.
[TIERS]
Every service is fixed-price, scoped, and built to pay for itself within 90 days.
Your shippers are asking AI where to ship. I use RankFixer to make your site explainable to Google and AI crawlers alike — not just optimized, legible.

[FRAMEWORK]
This is not a marketing claim — it's how I engineer. Every system I deploy is tested, recoverable, and traceable by design so it never fails silently, never gets gamed, and always explains itself.
