Eri Meilis
Senior Full-Stack Engineer
// Summary
Senior Full-Stack Engineer with 20+ years building complex B2B systems. I love architecture not for its own sake, but for the chance to shape systems around real business behavior, events, and processes — and for the moment when messy, tangled complexity turns into something clean, clear, and predictable. I work with CQRS / Event Sourcing, modular monoliths, and clean, strategy-driven cores; I've spent years modernizing legacy systems, leading cloud migrations, and building high-load infrastructure that doesn't just run, but stays maintainable for years.
