About

Portrait of Dainel Vera

I'm a Senior Software Engineer based in Denver, Colorado, with 19 years of experience in full-stack development, software architecture, cloud infrastructure, DevOps, and technical leadership. I build production applications with TypeScript, Next.js, Ruby on Rails, and Python, with a recent focus on ecommerce platforms, large language models, and AI-assisted software development.

I take products from initial concept through software architecture, implementation, and large-scale production. I've shipped iOS and Android applications with 100K+ downloads, scaled a Bitcoin ATM network past 2,700 machines, and led teams through infrastructure modernization and self-hosted deployments.

Recently, I've introduced LLMs and AI-assisted development workflows to engineering teams, mentoring engineers on Claude Code and Pi while teaching prompt engineering, context management, and practical techniques for applying AI to software development.

In my spare time, you can usually find me testing the latest open source LLM, opening Pokémon packs, hanging out with my wife and cat, or running around Speranza.
