United KingdomWhat I'm looking for
I am a Senior Software Engineer with 10 years' experience building scalable full‑stack systems across fintech, e‑commerce, and freelance technology sectors, focusing on React, TypeScript, Node.js, AWS and Generative AI (Llama3/4). I deliver measurable business outcomes by modernizing legacy systems, architecting cloud-native services, and embedding trustworthy AI practices into production workflows.
