Services

Software Development & AI Consulting

Two pillars, one standard: I build production-grade software and advise businesses on applying AI effectively – from strategy to operations.

AI & LLM Integration

Agents, RAG systems, tool use and structured outputs – integrated into your existing systems. With evaluation, guardrails and cost control for production use.

Profile

Who is behind it

Clean Code Solutions is me: Andreas Truszkowski-Graw, PhD in bioinformatics, working in professional software development for more than 20 years. In that time I have designed, built and operated enterprise systems, research software and web platforms.

That experience is my biggest lever today: I can tell where AI creates real value – and where classic engineering is the better answer. My clients get consulting and implementation from a single source.

Technology

Approach

From concept to production

  1. 01

    Understand

    A workshop on goals, use cases and feasibility – with an honest assessment of what AI can and cannot do.

  2. 02

    Prototype

    A working prototype in days instead of months – validated early thanks to AI-accelerated development.

  3. 03

    Production

    Hardening into a production system: tests, security, deployment and documentation to engineering standards.

  4. 04

    Operate

    Monitoring, evaluation and continuous improvement – so the solution stays reliable over time.
