Bern, Switzerland · systems, software and aviation
Complicated systems interest me. Working ones interest me more.
I’m Richie Eiger. I have spent my career working where software, networks, operations and people meet. I keep asking questions until the facts line up, then help turn a difficult situation into the next useful decision.

Where the real work starts.
I am most useful when a problem will not stay in one box. Architecture, operations and people are part of the same conversation, especially when the system is already under pressure.
See the whole system
I connect infrastructure, software, networks and operations in a design people can explain, challenge and actually run.
Stay useful in a crisis
First establish the facts. Then make the next decision safe, keep the people involved and do not confuse activity with progress.
Explain enough to decide
From Unix and telecommunications to current AI tooling, I enjoy going deep. It is only useful when it leads to a decision that somebody can genuinely act on.
A few chapters that shaped how I work.
This is not a full CV. These are the chapters that explain the habits behind the way I work today.
Core systems rebuilt while the business kept running.
These three engagements were not cosmetic upgrades. I helped move core operations from legacy mainframe datacentres to modern multi-tier, object-oriented solutions, including the difficult technical and organisational ground in between.
Banking · RTC & Swiss Bankers Traveller Check Center
Consulting across core processes, architecture and a modernisation programme that could not simply stop the business while it changed.
Swiss health insurer
Another substantial transition: taking established mainframe processes into a modern application landscape without losing sight of day-to-day operations.
Swiss OASI
Here too, the work joined continuity for the people using the system with a fundamental change of technology generation.
ECDA AG
I advise on technology, develop concepts, supervise projects and help when operations need a steady pair of hands.
Swisscom Mobile 1995–2001
At Swisscom Mobile, from 1995 to 2001, I helped build the mobile prepaid booking server. The work also took me into worldwide presales, integration support for several mobile operators and the crisis management that sometimes comes with live systems.
Swisscom B2C & B2B
Later, in a separate engagement for Swisscom B2C and B2B, I worked as an end-to-end solution designer on the convergence of wireline and wireless services.
FHNW
Operating systems, distributed systems, telecommunications and databases: foundations I keep coming back to.
I studied computer science in Bern and Systems Design Engineering in Waterloo. That is part of my educational path, and it belongs apart from the professional engagements above.
Bern & Waterloo
I am still curious. And I am still building.
From vibe coding to AI-agent-supported solution building
I am moving from AI vibe coding towards solution building supported by AI agents. Speed matters, but it is not the finish line. I care about the end-to-end user experience, operations that remain resilient over time, and software that somebody can still maintain two years from now. That also means being clear about the places where agents sound convincing but are not dependable yet.
Linux, networks and self-hosted systems
I still prefer systems I can inspect and understand. Reliability and security are much easier to discuss when nothing important is hidden.
Software, data and simulation
I build practical tools that make evidence visible, let people explore a decision and show what a complicated system is actually doing.
Flying brings everything together.
Aviation combines preparation, weather, machinery, communication and judgment. It is one of the best ways I know to stay humble about systems. On YouTube I share IFR flights plus cockpit and 360-degree views from my Cessna P210R.
Preparation, evidence and judgment, on the ground and in the air.
Things I have built
These are things I have made. Games was built entirely with first-generation vibe coding in 2022. EventIQ is a much older idea that began with LLMs and is deliberately still a work in progress.
