Los Angeles, California

Full-stack software engineer and systems architect with 9 years of biopharma software delivery, combining training in life sciences, chemical engineering, and business management to connect complex systems, translate operational needs into reliable software, and own delivery across applications, integrations, and infrastructure.

01

Development activity

A 53-week skyline generated from recent commit dates across selected repositories I maintain. Private repository identities are not published.

The visualization uses aggregate commit dates only. It is intentionally not a public inventory of private repositories and should not be read as GitHub's official contribution total.

02

Selected experience

Research software, product engineering, infrastructure, and AI-enabled systems.

Building products and the systems that build them

Designs and builds AI-enabled applications, native and web products, scientific informatics systems, and agentic development tooling. Work spans product strategy, UX, full-stack implementation, infrastructure, and operating workflows.

  • Architects production software across React, Swift, Python/Django, Go, GraphQL, SQL, and cloud infrastructure.
  • Builds agentic SDLC control-plane and execution-harness systems for observable, repeatable software delivery.
  • Leads product direction from research and information architecture through deployment and iteration.

Scientific software for discovery research

Built and led research-facing applications, enterprise integrations, scientific data workflows, and computing infrastructure within Discovery Research Informatics.

  • Delivered scientific and operational software across C#/.NET, Python, JavaScript, SQL, Linux, AWS, and internal research systems.
  • Supported LIMS and laboratory workflows, secure collaboration, cloud compute, cryo-EM workloads, and GPU-enabled molecular simulation environments.
  • Worked directly with scientists and operational stakeholders to turn research needs into durable systems.

Full-stack and backend systems in a high-throughput healthcare environment

Built software and integrations supporting operational and data-intensive workflows, contributing across application architecture, backend services, databases, and delivery infrastructure.

  • Worked across React/TypeScript, backend services, APIs, relational data, and cloud-native deployment patterns.
  • Focused on reliability, maintainability, and clear interfaces between operational systems.
