AboutReima
Full-stack developer with 5+ years building high-performance DTC brands on subscriptions and scale. I develop AI-powered workflows and tools, and ship team-ready codebases backed by cross-session AI agents that encode knowledge and skills.
My Approach
Every project I deliver has three non-negotiables: zero technical debt, measurable business impact, and a codebase the team can own long after launch. That means choosing architecture over shortcuts, holding performance budgets, and building tools that give non-technical teams real autonomy.
I have spent 5+ years partnering with ambitious DTC brands and agencies across the US and EU, engineering Shopify Plus storefronts, subscription systems, and full-stack solutions that break through platform limits. More recently, I have been building cross-session, team-ready AI agents and workflows that ship alongside the codebase. Every project includes CI/CD pipelines, staging environments, and documentation built to make the next developer's job easier.
