SOFTWARE DEVELOPER AI ENGINEER
I am Cengizhan Akbudak — software developer, AI engineer, and tech entrepreneur from Vienna. For more than two decades I have been translating demanding business logic into solid, high-availability system architectures, performant Go/Python backends, and production-ready open-source AI pipelines. No buzzwords — deterministic systems under load.
Technology with an entrepreneurial backbone.
I think entrepreneurially through my own company foundings, work uncompromisingly hands-on, and speak German, English, and Turkish.
Software has been my home from day one: my very first job took me to Internet-Online-Dienste GmbH as a programmer, and even as editor-in-chief and publisher of my own magazines, what I really built was the software behind them. Years as an independent developer and consultant turned that craft into architectural ownership: as co-founder and CTO of Go4System GmbH, I designed the entire platform of the taxi app Cangoo from the very first line — including a highly scalable Go backend, real-time data processing, and modern cloud infrastructure.
In 2024, I deepened my academic foundation in Artificial Intelligence at Johannes Kepler University Linz. Today I combine proven software engineering with state-of-the-art AI technology: I train, optimize, and deploy open-source models (LoRA/QLoRA) and retrieval infrastructures for real-world use cases.
Real engineering that delivers results.

Specialization & Tech Stack
LLM Fine-Tuning & RAG Systems
Fine-tuning of open-source language models via LoRA and QLoRA. Building complex Retrieval-Augmented Generation (RAG) pipelines with chunking, embeddings, re-ranking, and semantic vector databases.
Pragmatic API Design
Mathematically rigorous, deterministic web architectures and interfaces that maintain extremely low latencies even at extreme data volumes.
Infrastructure & Ingestion
Iron-clad fault tolerance. Event streaming via Apache Kafka, container clusters on Kubernetes, Write-behind-Ingestion, and automated CI/CD pipelines.
High-Availability Go & Python Backends
Scalable Go services and robust Python services. Built from real CTO and founding experience for business-critical real-time systems with relentless load requirements.
Launch the interactive system analysis.
