What I'm looking for

I'm looking to lead and build scalable full-stack and cloud products, combining architecture, AI-enabled features, technical leadership, mentoring, and reliable delivery for distributed teams.

I've spent 10+ years building scalable applications across Elementos Solution, Ficohsa Digital Factory, Kushki Payments, Kielsa Group, and Honduras' Ministry of Finance. I deliver full-stack products with NestJS, Node.js, TypeScript, React, Next.js, Angular, AWS, and PostgreSQL.

At Elementos Solution, I lead multi-tenant AWS architectures and agile teams while integrating Twilio, SES, and AI-assisted development workflows. For SEFIN, I built an Angular design system published as an NPM library and architected a microfrontends platform for large-scale government applications.

I've also led banking, payments, e-commerce, healthcare, mobile, and AI-enabled products, including Claude Vision photo validation, customer-support agents, and SMS chatbot workflows. I bring hands-on technical leadership through code reviews, mentoring, delivery management, and 11+ years teaching programming and ICT.
