Software Engineer — Fullstack, Infrastructure & Automation

Software engineer delivering product-focused systems end to end: Python APIs, React interfaces, third-party integrations, workflow automation, and production infrastructure across Linux, Docker, and virtual machines. Adaptable and accountable, with a track record of taking robust solutions from initial design through deployment and operation.

Driven by time efficiency: if part of a workflow can be automated, I automate it using the best available tools, leaving more time to solve meaningful business problems with clean, effective code.

Recognized for

  • Backend development with a strong focus on performance optimization, automated testing, and security.
  • Responsive React interfaces designed around intuitive end-user workflows.
  • Unix-based systems, deployment workflows, server management, and self-hosted infrastructure.
  • Cross-functional collaboration and product-focused technical decision making.
  • Workflow automation that reduces manual overhead and improves delivery efficiency.
