Curriculum vitae

Jan Ritt

Software developer focused on architecture and AI infrastructure.

My path: a decade of industry work, then the study qualification, then informatics at HTL Leonding. That persistence goes into every system I design.

Path

Before software came a decade of hands-on work. Keeping real-world processes running day after day taught me reliability, precision and process thinking, and it shaped what I expect software to deliver on a shop floor.

2011

Civil service, disability care

A year of direct responsibility for people; patience and reliability, learned early.

2012 – 2022

Logistics & industry

A decade of warehouse and shop-floor operations, six of those years in a single industrial plant. Processes, precision, accountability.

2019 – 2026

The deliberate switch

University entrance qualification alongside the job, then the informatics college full-time. Software is not an escape from operations; it is my way of improving them.

What I bring

Architecture, end to end

Designed and shipped a complete retrieval system: ingestion pipeline, vector DB, MCP interface, OAuth 2.1 security layer, deployed 24/7 on ARM hardware.

Benchmarks over impressions

Five-model embedding benchmark with statistical tests; the production model followed a documented quality-vs-deployability trade-off. I measure before I decide, especially when models or prompts change.

Agentic AI as daily practice

I build and run a model-agnostic harness for AI agents with self-developed skills, plugins and hooks, using local LLMs alongside cloud APIs. Tool-calling, structured output and guardrails are everyday material for me, not buzzwords.

Quality as a habit

Formal test protocols, E2E suites, 98% branch coverage on my tooling core, and gap analyses that drive my own refactoring roadmaps.
