— multi-agent systems.
Beyond the standard 4-tier ladder, AI integration is a primary offer — multi-agent systems, RAG, intelligent automation, and compliance. Production-grade, evaluation-driven, EU data-residency aware.
- Multi-agent design — plan/act/reflect loops with tool calls, supervisor patterns, and observable traces
- RAG & vector search — pgvector, Qdrant, or Pinecone with citation-enforced generation and eval harness
- AI ops & evaluation — token budget tracking, prompt versioning, A/B evaluation, regression detection
- Compliance & data residency — EU-region deployment, GDPR-aligned data flows, on-prem open-source options
We don't list services.
We ship fixes.
Every engagement starts with a symptom. Diagnose first, act second. Six problem shapes we've seen in the wild — with real before/after signals.
System on fire. Team can't say why.
Slow platforms, broken integrations, infra that fails at 3am. Dig in, find the real cause, fix it — fast.
Architecture won't take you to the next plateau.
Legacy holding you back. Modern, scalable replacements — monolith → microservices, .NET → React, without throwing away what works.
Traffic up. Costs up. Something snaps.
Optimize what you have, prepare for what's next. AWS, Redis, database tuning — engineered for load, not hope.
Everyone says "add AI." Nobody says how.
Real AI: multi-agent automation, intelligent categorization, moderation, workflows — shipped to production, not stuck in POC.
Fintech is hard. Regulated fintech is harder.
Payment systems, crypto custody, KYC/KYB, trading APIs. Built to pass audit and survive load.
You just need your site to stay up.
WordPress, hosting, DNS, SSL, backups. Monitored 24/7 by someone who actually picks up. Care clients get a reply within 4 business hours.
Systems we built.
Still running.
A selection — from CTO-led fintech platforms to WordPress sites that had to stay up. Every case study ships with real numbers and a real architecture, not founder quotes.

Frequently asked questions
How much does a website cost?
A website starts at €490; online stores and custom builds cost more. Every package and price is on the website page, and the final price is agreed in writing before any work starts.
How long does it take?
A smaller site is live in 5–10 working days once the content is ready. A larger site takes 2–4 weeks, an online store or multilingual site 4–8 weeks.
Do you only work in Gorenjska?
Numen is based in Blejska Dobrava, Gorenjska, and works with businesses across Slovenia and abroad. Most of the work runs over email and video calls; in Gorenjska we can also meet in person.
Where is the site hosted?
On our own servers at Hetzner in the EU, with daily backups, SSL and uptime monitoring. You can also keep your own hosting.
How fast do you reply?
Every enquiry gets a reply within one business day. Care clients get a reply within 4 business hours.
Will the website be mine?
Yes. The code, content and domain are yours, with no licence fee on the site itself. If you ever move to another developer, you get all the access you need.
Ready to fix, build,
or scale?
30 minutes, with me personally. I'll read your system like a log file and tell you what I'd do first. No pitch deck, no sales funnel.
