I'm an AI Engineer & Strategist (PhD in CS) who solves the #1 problem businesses face: 'We’ve spent 6 months building AI, but I still can't tell if it actually works.' Most businesses I work with are stuck with: • Features that look good but fail in production because they lack proprietary, robust logic. • Talented engineering teams who lack the specialized AI capabilities required to build auditable, verifiable systems. • Architecture that works for 10 users but will trigger massive security or cost liabilities when signing your first enterprise client. With 15+ years of experience and having architected 20+ high-stakes AI pipelines, I bridge the gap between complex AI research and agile, production-grade software engineering. I provide the senior technical expertise you need to eliminate repetitive workflows using production-grade, safe, and auditable AI automation and ensure your technology is an asset for your business or your next funding round. Recent work: • For a RegTech SaaS: Built a hybrid RAG pipeline with durable workflow orchestration (Temporal). Result: AI responses with 100% citation provenance for regulated document analysis. • For a wellness startup: Architected a 4-agent LLM coaching system with dynamic 6-layer prompt assembly and emotional intensity mapping. • For a cross-chain DEX: Engineered the backend for trustless atomic swaps between Bitcoin/Lightning and EVM/Starknet ecosystems. • Enterprise identity: Led the research and delivery of the KILT Protocol mainnet, including a Deloitte-partnered KYC integration. My pipelines consistently deliver: ✅ 40–80% reduction in manual work ✅ 99%+ accuracy, even in regulated environments ✅ Hours reclaimed per employee, per week ✅ Measurable ROI within 30–90 days How I help your business: ✅ AI strategy & advanced RAG: I provide the elite technical oversight your team needs to eliminate repetitive manual workflows, build safe AI systems, and ensure your technology is a major asset for your next funding round. ✅ Security and compliance: Deep expertise in building verifiable pipelines, secure cloud data flows, and SOC2-ready architectures. ✅ Engineering leadership: I work directly with your developers, streamline your sprint cycles, and implement CI/CD pipelines that ensure your team ships weekly, not monthly. ✅ Technical due diligence: I ensure your codebase and IP are fully optimized for institutional scrutiny during M&A or venture capital funding rounds. Technical expertise: • AI / LLMOps: Python, Pydantic AI, LangGraph, LangChain, PyTorch, Vector Databases, Graph-RAG, Semantic Search, Prompt Engineering, Model Evaluation, Fine-Tuning, Embeddings. • Backend & cloud infrastructure: TypeScript, SQL, Docker, Kubernetes, Terraform, AWS, Azure, GCP, Distributed Systems, CI/CD. • Automation & enterprise tech: n8n, Document Intelligence (Docling), LegalTech/FinTech compliance automation, Decentralized Identity (DID). I can quickly adapt to your stack and I am always happy to learn new tools. How we can work together: ✅ Technical audit and roadmap: We start with a deep dive into your current stack. I identify friction points in accuracy or scale and provide a written assessment with specific, technical recommendations. ✅ Fractional leadership: I join your Slack/Teams, manage the development cycle, and take ownership of the hard technical decisions so you can focus on growth. ✅ Specific sprints: Need a specific RAG pipeline or smart contract protocol built? I offer fixed-scope engagements for high-priority feature launches. Want to get started? Click the "Invite to Job" button. Tell me about your current stack and what would make our first call a success for you.

Hello Upwork, I am an experienced Blockchain and AI developer. I am a successful freelancer on Fiverr and self-employed. I always get the feedback that I am an extraordinarily talented programmer. I don’t shy away from new programming languages and I am quick in understanding new concepts and learning the skills necessary to deal with them. Speaking of languages: I speak English and German, my mother tongue. An example of my work is the app Reward, which I developed in 2017. With a modern design and a simple but smart concept, it acquired over 101,000 devices and was used by over 2,000 people every day. Later, I developed the app Ecofai with a friend of mine to bring an AI sustainability expert to the people. At 20, I developed my first cryptocurrency, Wildfire, which was used all over the world. It was met with much appreciation from the crypto community at the time. My personal premine (5% of the total supply) was priced at $22,500,000 for a while. (Keep in mind: price ≠ what I earned.) Since then, I have created many other coins for my customers. I am currently self-employed as a Blockchain and AI developer. I get many orders through Fiverr, where I have the highest level, and am a 5-star rated Pro seller with many repeat customers. Please consider ordering from me if that was appealing to you. Thank you in advance. :)
