About

Professional summary

I am a Frontend Lead and Senior Frontend Engineer with 11 years of experience building scalable web and mobile products. I specialize in modernizing legacy systems and delivering frontend architecture across Angular, React, React Native, TypeScript, and Node.js ecosystems.

I have led teams and frontend delivery for enterprise applications, micro-frontends, web components, monorepos, and design systems. My work includes technical decision-making, solution design, mentoring, code reviews, stakeholder demos, and cross-functional collaboration in Agile environments.

I build full-stack solutions using Node.js, NestJS, Express.js, PostgreSQL, MySQL, MongoDB, Redis, Prisma, Firebase, and Supabase. I am experienced in creating reliable APIs, dashboards, mobile features, financial platforms, and customer-facing SaaS products.

I focus strongly on performance, quality, and production reliability. I use automated testing, TDD, Jest, React Testing Library, Playwright, CI/CD, feature flags, Datadog, and Splunk to improve software quality and safely manage releases.

I also use AI-assisted and agentic development practices, including spec-driven development, context engineering, LLM agents, MCP tooling, automated verification, and AI-supported code review. I create reusable agent workflows and documentation that help teams navigate complex legacy systems and accelerate delivery.

I am based in Aguascalientes, Mexico, and have extensive experience working remotely with distributed teams and international clients.
