Anja K.

AI & Backend Developer | Building LLM-Powered Systems, Automation Pipe

Hi 👋 I’m Anja, an AI Automation Engineer with a strong focus on backend systems, integrations, and production-ready AI workflows. I’ve worked on a range of projects involving AI chatbots, API integrations, and automation pipelines, using Go and Python as my main tools. My experience includes building GPT-based conversational systems, designing end-to-end automation workflows, and developing reliable backend services that connect multiple external systems. I’ve also worked on more specialised AI projects, such as training YOLO models and integrating them into the CARLA simulator for adaptive cruise control, building image recognition systems for clothing classification, and fine-tuning models like Wav2Lip and Stable Diffusion XL for production use. Alongside this, I’ve automated video workflows with FFmpeg and built data extraction and automation tools to reduce manual work. I enjoy working in environments where systems evolve, requirements aren’t always perfectly defined, and the goal is to turn complex ideas into stable, maintainable solutions. I’m comfortable collaborating closely with designers, product teams, and other engineers, and I value clear communication and long-term working relationships. Core skills: - Go & Python backend development - API design, integration, and automation - AI chatbot and LLM-based systems - Model fine-tuning (Wav2Lip, Stable Diffusion XL) - Computer vision (YOLO, image recognition) - FFmpeg video processing pipelines - Web scraping and workflow automation I’m always keen to learn, improve, and take ownership of meaningful technical challenges. If you’re looking for someone who can build reliable systems and adapt quickly as products grow, I’d be happy to talk. Best, Anja
