I am Germán Küber, a Staff Engineer specializing in Systems, AI, and Blockchain technologies, recognized as a Microsoft MVP for eight consecutive years. Over the past 15+ years, I have built scalable systems that move money, ship products, and operate at low latency, including MEV trading pipelines in Rust handling over $50M in daily on-chain volume with sub-10 ms execution times. I am passionate about building and leading engineering teams, driving architectural decisions, and remaining hands-on with production code across multiple languages such as Rust, Python, .NET, and Node.js.
I founded Net-Baires, Argentina's largest .NET developer community with over 100,000 members, and have delivered more than 80 international technical talks at conferences like .NET Conf, DevFest, and vOpen across LATAM and Europe. My experience spans from developing real-time AI platforms with multi-provider LLM orchestration to designing enterprise architectures and decentralized marketplaces using zero-knowledge proofs.
As a co-founder and lead AI architect of KliverAI, I built an AI training platform supporting 500+ users, focusing on scalable training simulations and real-time voice and AI pipelines with sub-200 ms latency. I have benchmarked and integrated multiple TTS/STT and LLM providers to optimize latency, cost, and quality, while pioneering adaptive simulation engines and privacy-preserving evaluation marketplaces.
In my fractional CTO role at Rocking Product, I restructured an 8-engineer team, improved product matching with AI-powered image embeddings, and introduced Spec-Driven Development and AI-driven workflows. I also led a full-stack migration to modern .NET technologies, enhancing scalability and compliance.
Previously, I served as Lead Software Engineer at Borderless Capital, designing and operating MEV searcher pipelines in Rust and Python, achieving high throughput and low latency. I contributed to blockchain tooling, conducted technical due diligence, and led team growth and mentoring. My broad skill set includes cloud infrastructure, distributed systems, observability, security, and frontend technologies, complemented by strong soft skills such as mentorship, communication, and problem-solving.
I am an EU citizen based in Las Palmas, Spain, open to remote opportunities across Europe and the Americas. I actively contribute to open-source projects, maintain a technical YouTube channel, and engage in public speaking and community leadership. Outside of technology, I have a passion for performance arts including stage magic, stand-up comedy, theater, and hypnosis, which enhance my communication and facilitation abilities.
