About me

Software engineer crafting resilient, product-focused experiences

I partner with founders and product teams to ship thoughtful web applications— blending systems thinking, clean execution, and strong collaboration. My process is grounded in clarity, rigorous standards, and measurable outcomes.

Focus areas

  • Deep product partnership

    I translate abstract goals into actionable roadmaps, pairing strong technical judgment with user empathy.

  • Scalable architecture

    My foundations favor clarity, observability, and resilience so products stay nimble as teams and traffic grow.

  • Delivery with polish

    I sweat the details—from accessibility to performance budgets—so every release feels intentional and crafted.

Principles I lead with

  • Clarity first

    Align stakeholders quickly with transparent communication and crisp documentation.

  • Measure what matters

    Use data and feedback loops to steer iteration, not just instinct.

  • Design with empathy

    Think through edge cases and accessibility from day one.

  • Invest in tooling

    Automations and guardrails keep teams shipping safely at pace.
