Oliver Baer / LüneburgSoftware that works on Monday
I buildserioussoftware.
Founder. Architect. Engineer. Still curious.
From medical systems to AI infrastructure, I turn complicated product ideas into dependable tools people can actually use. Clear decisions. Working software. No mysticism required.

Now / Three seats, one person
What’s
on the
desk?
The seats stack on purpose. Each product supplies a different kind of reality check to the others.
01
02Senior DevOps Architect · AI Advisor
Independent Consulting
Designing the infrastructure that lets AI products ship reliably — CI/CD, container orchestration and observability without theatre.
Founder · Chief Architect
nyxCore Systems (GmbH in Gründung)
The orchestration brain behind a growing product ecosystem: workflows, durable context, specialised personas and self-repair.
Founder · Product Owner
Q-Records Storemanager
A full-stack SaaS for vinyl stores and second-hand retailers — the product where abstract architecture has to face a real shop counter.
Aristaeus / The Cultivator of Solutions
“What if we solved the problem upstream of the problem?”
A voice in the machine.
Aristaeus carries Oli’s register inside nyxCore: anticipatory innovation, cross-domain synthesis, lateral thinking and product vision — hardened by Ipcha self-check, because a visionary who refuses to be stress-tested is only a pitch deck.

Turns real questions into source-grounded answers, personal learning cards and measurable mastery.
New product / by nyxCore
Etch.
Dialogic learning platform
Turn every question into lasting knowledge.
For organisations whose critical knowledge is scattered across documents, processes and individual experts, ETCH transforms real questions into source-grounded answers, personal learning cards and measurable capability — instead of merely storing knowledge or answering it once.
Open ETCHAnswer
Receive a source-grounded answer from your organisation's knowledge.
Etch
Turn the useful part into a personal learning card.
Review
Repeat it when spaced-repetition science says it matters.
Mastery
Make individual and team capability visible.
Knowledge is not retained because it was available. It is retained because it was used, recalled and reinforced.

The arc / Twenty-eight years
Built in the real world.
Medical systems taught precision. Media taught scale. Manufacturing taught consequence. Retail taught the counterexample. AI infrastructure ties those lessons together.
- 1998 — 2004
01 / Medical devices
Philips Medical Systems. Software for equipment radiologists depend on. Six years of learning that software can have weight.
- 2006 — 2007
02 / Consumer portals
Surf Media GmbH. High-traffic billing tools and third-party API integrations. The scale year.
- 2007 — 2014
03 / Media intelligence
Kantar Media GmbH. Zend, Solr, OCR, AWS clusters and seven years of turning noise into signal at industrial scale.
- 2013 — 2015
04 / South America
Salome Media GmbH, co-founded. Social-media monitoring and product-placement analytics for Spanish-speaking markets.
- 2014 — 2020
05 / Manufacturing
Managing director at Druckgassysteme Wittler: production, prototypes, 3D printing, quotations and customer relations.
- 2021 — 2024
06 / Back into software
Go microservices, Kubernetes, exhibition applications, Pimcore and a GraphQL gateway replacing legacy XML.
- 2025 — now
07 / AI-native infrastructure
Consulting, Q-Records and nyxCore. Three seats, one arc. Cross-domain synthesis as a specialisation.
Three agents running in production
Father of three. The longest-running deployment he maintains: three small entities that started stateless, acquired goals he did not specify and are approaching autonomy on their own definitions of correctness.
Restaurant kitchens
The composure-under-pressure line in the CV is not a metaphor. Professional kitchens taught ten-things-at-once with no dropped plates — the same mental shape as a production incident at two in the morning.
Manufacturing floor
Six years running a manufacturing company. Shipping becomes a habit when broken things stop a physical line and every abstraction eventually meets steel, time and a customer.

One practitioner. Whole path.
I work between architecture and the shop floor: from an ambiguous product decision through implementation and into stable production. My stronger skill is often deciding what the product does not need.
If your project needs a twenty-seat consultancy, this is the wrong page. If it needs someone who has shipped across six domains and still answers his own email, this is the right one.
