I am a Systems Engineer and Senior Backend Engineer with more than nine years of experience building, supporting, and maintaining production software. I specialize in Python, Ruby on Rails, JavaScript, REST APIs, authentication, relational data modeling, and third-party integrations.
I design backend services with an operational mindset shaped by hands-on application support and incident management. I have supported national retail brands in high-pressure production environments, triaging critical incidents, meeting SLA commitments, escalating issues appropriately, and maintaining operational continuity.
I build secure API-driven applications using JWT authentication, PostgreSQL, UUID-based data models, database migrations, Docker, AWS, and CI/CD practices. My experience includes building a medical appointment management platform in Ruby on Rails integrated with Google Calendar.
I also work with AI and automation technologies, including Python-based AI agent integrations, n8n workflows, and Robocorp RPA. I enjoy automating repetitive processes and creating practical solutions that improve product and support workflows.
I communicate clearly with clients, product stakeholders, end users, and engineering teams. I am available to start immediately as an independent contractor and am focused on remote backend engineering, API, automation, and technical support opportunities.
