About

Professional summary

I am an AI-focused software engineer and technical leader with extensive experience building full-stack, backend, and integration platforms. I specialize in Python, Java, TypeScript, React, cloud infrastructure, and production-grade software systems.

I lead engineering initiatives from architecture and planning through implementation, testing, deployment, and ongoing maintenance. My experience includes building large-scale API integration platforms, enterprise applications, asynchronous processing systems, and customer-facing web applications.

I am particularly focused on AI engineering and agentic development workflows. I use Claude Code, Anthropic Claude API, MCP servers, FastMCP, subagents, and AI-assisted development practices to improve software planning, implementation, testing, and operational support.

I have led teams, established engineering standards, mentored developers, and made technical architecture decisions across multiple projects. I combine hands-on coding with technical direction, quality practices, CI/CD automation, and scalable software design.

My core technical strengths include Python, Django, FastAPI, Java, React, Next.js, PostgreSQL, Redis, RabbitMQ, AWS, Docker, REST APIs, GraphQL, and automated testing. I have experience delivering secure multi-tenant SaaS platforms and integration systems supporting thousands of customer accounts.

I am based in Costa Rica and work remotely with teams in United States time zones. I am interested in senior and lead-level AI engineering and software engineering opportunities where I can build reliable systems and help teams adopt effective AI-assisted development practices.

Career history

Full-Stack ERP & Payroll SaaS Developer Goki

I design and develop a multi-tenant ERP and payroll SaaS platform independently, taking the product from database design through deployment. I use AI-assisted development workflows to support planning, implementation, testing, and maintenance.

I build the backend with Python, Django, Django REST Framework, PostgreSQL, Redis, Celery, REST APIs, JWT authentication, OpenAPI documentation, AWS, Docker, Nginx, and Gunicorn. The platform includes Anthropic Claude API integration, MCP servers built with FastMCP, audit logging, Google OAuth, cryptography, and multi-tenant permissions.

I develop the frontend using TypeScript, React, Next.js, Material UI, Tailwind CSS, React Hook Form, Zod, SWR, Axios, and NextAuth.js. I maintain quality through pytest, pytest-django, factory-boy, Playwright, GitHub Actions CI/CD, Claude Code, agentic workflows, skills, and subagents.
