👋 Hello

I'm a backend engineer focused on building systems that move money, scale reliably, and stay observable. My work spans payments infrastructure, CI/CD tooling, and distributed microservices — with experience in regulated fintech and developer platform environments.

TL;DR

  • 🛠️ Backend Engineer — Payments Infra & CI/CD
  • 🧭 Available for backend infrastructure roles (remote or NYC-based)
  • 🤝 Trusted by teams shipping production-grade financial systems

🔧 Recent Work Highlights

  • Payments Infrastructure: Refactored Interac e-Transfer reception flows handling 500K+ daily transactions, reducing latency by 53%
  • CI/CD Observability: Built GitHub-native tooling analyzing flaky tests and systemic pipeline issues across 10K+ repos
  • Infra Modernization: Migrated distributed monitoring pipelines from legacy storage to SQL-backed telemetry with near real-time alerts

🧠 Interests

  • Java, Spring Boot, RabbitMQ, and event-driven architecture
  • CI/CD pipelines, observability, and systems that fail loudly
  • Financial protocols, transaction integrity, and system design
  • Teaching through diagrams, writing, and mentorship
  • Mental health and sustainable growth in tech
