Principal software engineer with 18+ years of experience designing and evolving business-critical platforms where correctness, traceability, and operational reliability are first-class concerns.

My background is in distributed systems, transaction processing, and platform engineering, with a long history of owning complex domains end-to-end — from core calculation engines to cloud-native execution pipelines. I tend to work at the boundary between domain-heavy business logic and modern infrastructure, helping teams make large systems more predictable under scale.

I’m most effective in environments where:

• data integrity and determinism matter
• failure modes must be understood and contained
• systems are expected to evolve without constant rewrites

I focus on making complex systems easier to reason about:

• Clarifying ownership boundaries between domain logic and infrastructure
• Reducing failure blast radius through isolation and idempotent design
• Designing for operational visibility, not just functional correctness
• Balancing delivery pressure with long-term system health

I’ve spent much of my career inheriting long-lived systems and helping them evolve safely — improving reliability, performance, and maintainability without disrupting the business.

My public repositories primarily reflect experimentation, learning, and reusable tooling patterns, rather than client-specific systems. I use open source as a way to explore architecture, packaging, testing strategies, and developer experience in isolation from proprietary environments.

In parallel, I maintain private research projects focused on:

• platform automation
• system introspection
• developer productivity tooling
• large-scale codebase analysis

• 🏗️ 18+ years building and operating complex software systems
• ⚙️ Deep experience with high-throughput, deterministic processing
• ☁️ Extensive work in Azure-based compute and data platforms
• 🧪 Strong emphasis on testability, observability, and correctness

I’m always open to conversations around distributed systems, platform engineering, and building reliable software at scale.
