About Me

Introduction

I am Thomas Derflinger, an independent software developer and entrepreneur. This blog documents my projects and insights on topics that drive innovation in software development.

As a freelance software developer, I am available for client engagements, with a preference for remote or hybrid projects within Europe. My primary areas of expertise include GIS, IoT, electronics, and educational technology. I also like Virtual/Extended Reality (VR/AR/XR).

I help organizations accelerate innovation and bring strategic perspectives to technology initiatives. My focus is on delivering solutions that enhance operational efficiency, create competitive advantages, and drive measurable business results.

Software Stack

The software tech stack I am very familiar with:

JavaScript and TypeScript are my favorite languages and I have already worked as a trainer for JavaScript courses. React and Vue are my favorite frontend frameworks. Python is also a well-liked language of mine, and I also appreciate Go and Java. I have good knowledge of the Content Management System (CMS) Strapi, which is also used for this blog. For frontend development, I often used Storybook to program the components in isolation.

The developement IDE I currently prefer is VS Code. I use the GitHub Copilot for agentic software development. My favorite AI coding models are Claude Opus, Mistral Devstral and GPT Codex.

In the AI space, Ollama is really useful for managing and programming local models like Qwen. As a higher-level way to program AI system, I value the DSPy framework.

Languages Spoken

I am fluent in German, English, French and Spanish. Also, I know some Romanian (B1), Czech (A2) and Mandarin Chinese (A2).

Certifications

I hold certifications in TypeScript, Linux Administration (LPIC 1 - 101), and am an OMG UML Professional. Additionally, I am Python PCEP certified and a Graph Developer Associate for Apollo GraphQL. I have completed the Introduction to RISC-V course from the Linux Foundation and the AI Fluency course by Anthropic.
