Location: Seattle, Washington, United States
Profile: https://flows.cv/felipeheliszkowski

Senior Software Engineer with eight years of experience building payments infrastructure and financial systems at scale. I specialize in platform architecture — decomposing complex
  legacy systems into well-bounded services, designing settlement and funds flows for regulatory compliance, and shipping end-to-end payment APIs that move real money. I'm energized by the
   intersection of technical complexity and business constraint: routing funds across bank accounts, building developer tools that teams actually adopt, and driving cross-team alignment on
   architecture decisions that touch multiple codebases and stakeholders. Outside of payments work, I experiment with AI-assisted development workflows and build internal tooling that
  accelerates the team around me.

  Core Competencies

  - Payments & Financial Systems: Settlement routing, funds flows, payment APIs, regulatory compliance, merchant integrations
  - Backend & Distributed Systems: Microservices re-architecture, event-driven systems, Java, Kotlin, Go
  - Platform & Developer Experience: Internal tooling, testing infrastructure, API design, cross-repo contributions
  - Cloud & Infrastructure: AWS, Kubernetes, Terraform, IaC
  - AI & Tooling: LLM-assisted development, AI agent workflows, developer productivity tools
  - Technical Leadership: Architecture reviews, cross-team coordination, code review culture, domain expertise across multiple systems
