Fiona D'Mello

I’m a full-stack engineer with 6+ years of experience building and owning products end-to-end, from architecture to deployment. I design before I build and write specs before I code, using Claude, Claude Design, and Claude Code across the full development lifecycle—for product thinking, UI design, and implementation—in a structured, reviewed process where accountability stays with me.

My best work is on greenfield products in small teams, where I take full responsibility for outcomes. At Forschungszentrum Jülich, I owned the entire frontend layer of a Next.js and TypeScript web application for non-technical researchers, made independent architecture decisions, and improved team efficiency by 48% through better planning and development processes; earlier, at Infosys, I helped deliver and secure a new client quickly, implemented AWS-based solutions, and reduced deployment cycle times by 20% with Serverless Offline for local AWS testing. I also build personal products like Wandel, where I’m the sole product owner, designer, and engineer, implementing Supabase row-level security (RLS) and shipping a deployed PWA using a React/TypeScript stack.
