About

// who

I'm a senior software engineer and team lead focused on backend development, software architecture, and scalable enterprise systems. Since March 2025 I've been on Datasoft's accounting team, building integration-heavy backend solutions for business-critical enterprise workflows.

My recent work centers on .NET 8/9, domain-driven design, Clean Architecture, event-driven systems, external integrations, tenant-aware data, and observability. I'm also increasingly focused on AI-assisted software development — exploring how tools like Claude Code, OpenAI Codex, and GitHub Copilot can sharpen planning, development workflows, and engineering productivity.

Coaching

// beyond code

Outside of engineering, I'm a Level 1 Volleyball Coach. I've played since school — including as a team captain in high school — and coaching now lets me pass on what the game taught me: teamwork, discipline, and helping people grow.
