Bangor, United Kingdom - 12:50 am local time
I am an AI Full Stack Engineer with 4+ years of hands-on experience building production-grade SaaS platforms and AI systems used by real users not just demos.

I work end-to-end: architecture → development → AI integration → deployment, with a strong focus on scalability, clean code, and long-term maintainability. I’ve delivered modern SaaS products, AI-powered tools, admin dashboards, and cross-platform apps for startups and growing businesses.

My core strength is building real AI systems, not just API integrations. I design and deploy LLM pipelines (RAG, vector search, evaluation, tracing) and AI agents that operate reliably in production.
