Autonomous AI Operations

Event-Driven AI Platform

From Multi-Agent to Single-Agent – same power, radically simpler

An autonomous platform orchestrating development workflows: from code reviews to CI/CD to automated deployment.

73%
Cost Reduction
5→1
Agents Simplified
Event-Driven Architecture
Webhooks → Event Bus → Handler → Actions. Every event is persisted, every action is traceable and idempotent.
Multi-Model Orchestration
Sonnet for daily tasks, Opus for complex analysis, Haiku for cron jobs. Automatic model selection based on task complexity.
Custom CI/CD Pipeline
Custom GitHub App with Check Runs, Annotations, and PR Comments. Full control over the build process.
Architecture Evolution
From 5 specialized agents to a single agent – same capabilities, 73% cheaper, radically simpler to maintain.
Quality Gates
GSD Framework: TypeCheck, Stub Detection, Wiring Verification. No AI-generated code without quality checks.
Observability
Prometheus + Grafana dashboards for real-time monitoring of all AI operations and costs.
Research Intelligence

Automated Market Research

From Signal Detection to Idea Validation

An intelligent research pipeline that automatically detects market signals, evaluates ideas, and feeds them into the operations pipeline.

Signal Detection
6 research providers continuously scan for relevant market signals, trends, and opportunities.
BIGS Scoring System
Structured evaluation of every idea by Business Impact, Innovation Grade, and Strategic Fit.
Portfolio Analysis
Automatic diversity checks and portfolio balance. Prevents concentration risks in idea selection.
Pipeline Integration
Direct integration into the operations platform. Validated ideas automatically become prioritized tasks.
Production Infrastructure

Self-Hosted & Cost-Efficient

Enterprise-Grade Infrastructure for ~€35/month

No vendor lock-in with cloud providers. Own infrastructure on Hetzner with full control over data and costs.

Uptime
Hetzner Private VLAN
4 servers in a private network infrastructure. Isolated, secure, GDPR-compliant.
Hybrid Deployment
Docker + Caddy + systemd. Proven, simple, reliable. No Kubernetes overhead for this scale.
SQLite WAL
Event persistence with SQLite WAL instead of PostgreSQL + Redis. One file instead of three services.
Full Observability
Prometheus, Grafana, log aggregation. Complete transparency across all systems.
Evolution

From Product to Ecosystem

Phase 1: Build the Product

BuchhaltGenie – AI accounting for Austria. From the first line of code to a production-ready platform.

Phase 2: AI Operations

Multi-agent system for automated development workflows. 5 specialized agents orchestrating the entire dev lifecycle.

Phase 3: Simplification

Architecture revolution: Single agent replaces multi-agent. 73% cheaper, same capabilities, radically simpler.

Phase 4: Research Intelligence

Automated market research and idea discovery. The ecosystem finds and validates new opportunities autonomously.

Key Learnings

What I Learned Along the Way

Simplify Ruthlessly
5,000 LOC → 1,500 LOC event bus. Less code is always better code. Complexity is the enemy of reliability.
AI Slop Prevention
Quality gates before every commit. AI-generated code needs stricter review, not less. The GSD framework stops bad code before it lands.
Production-Grade or Nothing
30K+ tests, 0 TypeScript errors. No feature without tests, no exception without handler. Quality is non-negotiable.
Own Your Infrastructure
Self-hosted CI instead of GitHub Actions. €35/month instead of €350. Full control, full transparency, no surprises.
