About & technical practice
UK / UAEEngineering approach, daily agentic methodology, and core domain proficiencies.
I’m Otis, a Senior Full Stack Engineer based between the UK and UAE. I enjoy taking ownership of a problem, understanding the people it affects, and seeing the work through to production.
At ROLI, I work across the customer journey, from product discovery to purchase and onboarding. Before that, I built HAWK at OLR and led four engineers bringing the product to life.
Agentic tools are part of my daily practice: planning, research, refactoring, building features, and writing tests. I use Claude Code, Cursor, GitHub Copilot, and Codex, alongside MCP servers, agent skills, and sub-agent workflows. Code review, readability, security, and documentation still deserve the same care.
Outside product work, I build AI-powered personal tools, volunteer in residential construction, and teach introductory programming to young people.
