Staff Software Engineer & Core Platform Lead

Location: San Mateo, CA

Staff engineer with 15+ years architecting and delivering scalable frontend and platform systems for high-traffic applications. I bring both startup versatility — wearing many hats across full-stack engineering in fast-moving environments — and enterprise depth, leading a team of six driving micro-frontend architecture, monorepo strategy, and shared platform capabilities that deliver measurable business impact.

Ipsy Startup

Staff Software Engineer, Core Platform Lead

  • Operated in a startup environment — contributed across the full stack (frontend, BFF, infrastructure, observability) beyond core platform responsibilities, adapting rapidly to evolving product priorities and org structure.
  • Led a Core Platform team of 6 engineers, owning architecture and technical direction across multiple high-traffic applications.
  • Architected a multi-tenant Next.js micro-frontend platform enabling independent deployments and scalable release cycles.
  • Established an Nx-based monorepo strategy that improved build performance by ~50% and centralized shared dependency management.
  • Built shared platform libraries — UI components, analytics, logging, image optimization — cutting code duplication by ~30%.
  • Created a centralized design system and Storybook platform, aligning Figma design tokens with production components in Chakra UI.
  • Designed a Backend-for-Frontend layer with tRPC and Node.js, improving type safety and simplifying client-server integration.
  • Improved application performance by ~70% through ISR, CDN caching, edge functions, lazy loading, and bundle optimization.
  • Diagnosed and resolved a Contentful persisted-query defect, preventing ~$100K in projected overage costs.
  • Implemented a Datadog observability platform (logs, metrics, traces), reducing incident detection and resolution time by ~25%.
  • Provisioned and managed AWS infrastructure using Terraform, enabling repeatable, version-controlled environment setup across staging and production; also codified all monitoring dashboards and alerts as infrastructure-as-code, ensuring consistent observability across environments.
  • Deployed micro-frontend applications to Netlify and instrumented them with OpenTelemetry (OTel), enabling distributed tracing across all micro-frontend boundaries — improving latency visibility, catching p95 regressions earlier, and reducing mean time to resolution for production incidents.
  • Standardized analytics and experimentation across micro-frontends using Amplitude, GTM, and Statsig, driving data-informed feature rollouts and A/B testing at scale.
  • Conducted technical interviews for frontend and platform engineering roles, helping maintain a high hiring bar for the team.
  • Improved and standardized the team's branching strategy (develop → staging, main → production) and CI/CD pipeline via Jenkins — enforcing TypeScript checks, Jest tests, ESLint, and Snyk vulnerability scanning as hard gates on every PR, with code-owner approval required before merge; merges trigger automatic deployments to the respective environment.
  • Established code review standards, RFC process, and PR templates to streamline collaboration and raise engineering quality across the platform team.
  • Actively participate in Agile ceremonies — sprint planning, retrospectives, and backlog grooming — as the platform team lead, aligning engineering priorities with product roadmap.
  • Served as on-call incident commander on a weekly rotation and as the primary escalation point for production incidents — leading triage, coordination, and resolution across teams including during critical peak sales events like Thanksgiving and Christmas.

Qiagen

Senior Software Engineer

  • Led an Angular modernization initiative that improved application performance by ~50% and established a scalable UI architecture.
  • Designed and implemented complex, data-intensive workflows for genomic analysis, optimizing rendering for large datasets.
  • Developed advanced visualization components with Chart.js and Vis.js to represent gene-phenotype relationships.
  • Enhanced application responsiveness through optimized state management and streamlined data processing.
  • Partnered with product managers and domain experts to deliver clinically accurate, high-performance user experiences.

Western Union

Senior Software Engineer

  • Designed and developed scalable Angular frontend platforms supporting global money-transfer workflows.
  • Resolved multiple credit card fraud issues with the Cardinal provider, saving up to ~$500K annually.
  • Built backend services with Java / Spring and Node.js APIs for seamless integration with frontend systems.
  • Implemented OAuth2 / JWT authentication and SSO integrations to strengthen security across partner ecosystems.
  • Delivered partner-facing APIs and hosted pages enabling integration with global partners including Kroger, UK Post Office, and La Banque Postale.
  • Improved application performance by ~30% by migrating legacy jQuery applications to a modern Angular architecture.
  • Created mock services with Node.js and AWS (Lambda, DynamoDB) to decouple frontend development from backend dependencies.
