Available to hire
I’m Imre Barczi, a seasoned software engineer with 25 years in IT across developer, product management, and leadership roles. I enjoy building end-to-end systems and excel at full-stack development (JavaScript/Node.js) with a strong emphasis on agile, architecture-driven thinking, and hands-on coding. My background spans strategy, product design, and mathematics, giving me a broad perspective on technical systems. I’ve consistently delivered production-grade solutions from concept to deployment, not just prototypes.
Recently I’ve focused on AI-assisted development, pushing the boundaries with ChatGPT, Cursor, and multi-LLM architectures, incorporating cost controls, fallback logic, and thoughtful prompt engineering. I also work with React on the front end and blockchain technologies on the back end, delivering NFT platforms, DeFi contracts, and crypto trading bots. Beyond software, I’ve contributed to ambitious projects in media and entertainment, including restoring archival material, creating online portals and newsletters for local markets, and building innovative technologies for national TV and other media initiatives in Hungary.
