About Febrianto

AI/ML Engineer with 15+ years of experience designing and deploying production-grade AI systems across
healthcare, fintech, and cloud.
I specialize in building intelligent systems that bridge modeling and infrastructure — from LLM fine-tuning
and RAG pipelines to scalable inference on AWS, GCP, and Azure. I’ve led end-to-end projects that reduced
triage time by 18% at Lyra Health, deployed Claude-based RAG frameworks at Anthropic, and built large
scale fraud detection at AWS. Passionate about transforming foundation models into reliable, real-world
applications. Experienced in building Agentic AI systems, including multi-agent orchestration, tool-calling
workflows, and autonomous LLM pipelines.
Blockchain Engineer and Senior Frontend Architect with extensive experience building modern Web3
platforms, high-performance web applications, and Mobile Solutions.
I specialize in developing scalable decentralized applications while combining Strong UI/UX Design principles
with robust frontend engineering using React.js, TypeScript, and React Native.
My work focuses on Bridging Blockchain Infrastructure with intuitive user experiences, transforming complex
decentralized systems into accessible and reliable applications.
I
have experience designing and implementing Web3 Interfaces, Wallet Integrations, Smart Contract
Interactions, and high-performance frontend architectures that support real-world blockchain products.
I also bring a strong background in UI/UX design, ensuring that products are not only technically sound but
also visually refined and user-centered.
From concept design and prototyping to production-ready interfaces.
Passionate about building Next-Generation Digital Products, I enjoy working at the intersection of blockchain
technology, modern frontend engineering, and User-Focused Design, Delivering Secure, Scalable, and
Elegant applications across Web and Mobile Platforms.
