About Me
Building Digital Experiences That Matter
I'm a Senior Software Engineer passionate about creating high-performance front-end systems for enterprise SaaS applications. With expertise spanning modern frameworks like React, Next.js, and Vue, I build scalable, modular architectures that drive business impact.
My recent focus has been on integrating LLMs and AI-driven workflows directly into production UIs, leveraging OpenAI APIs, LangChain, embeddings, and RAG to create intelligent, conversational experiences.
I believe in accessible design (WCAG 2.1), rigorous testing, and mentoring teams to elevate code quality and developer experience across the board.
