About

I'm a product-minded software engineer who cares less about which layer the code lives in and more about whether the thing we ship actually moves the needle. The problems I chase live at the intersection of product, design and engineering: what are we solving, for whom, and how do we know it worked?

My default mode is iteration — I'd rather push a thin end-to-end slice into users' hands and learn from real feedback than polish something nobody asked for. That leans on the practices that make fast, safe shipping possible: CI/CD, tight feedback loops, and Extreme Programming habits like honest tests and small reversible steps.

Increasingly, a lot of that building happens with AI. I design agentic workflows that move from idea to reviewed PR faster — letting LLM agents plan, write and test, always with a human in the loop for anything that ships. What I won't trade away: accessibility, performance, tests that tell the truth, and AI that earns its place in a real codebase.

Experience

  1. 2026 — Present

    Senior Product Engineer · Service Club

    Building ServiceClub Perks (an employee benefits platform, web + mobile) as a greenfield project from day zero. I prepared the codebase for AI-assisted development, defining shared skills and rules across Cursor and Claude Code and aligning components with the Figma design system to enable design-to-code. I also work closely with product to prioritize and ship incremental releases, introduced a behavior-first testing culture across the monorepo, separated DTOs from view models for a predictable API-to-UI data flow, and migrated non-SSR admin dashboards to a Vite + TanStack Router SPA.

    Software Engineer · Qualifyze

    Led the development of Quality Insights Platform — an interactive data dashboard clients relied on to make high-stakes decisions about their suppliers. Helped shape what information to surface and how, so those decisions were better informed. Led its migration to Next.js (50%+ performance gain), helped build a ~50-component design system that sped up delivery across products, and expanded into the backend toward a fullstack role. I also became a frontend technical reference on a team of ~30 engineers.

  2. ServiceClub Perks

    Greenfield employee benefits platform (web + mobile), built from day zero. Working closely with product to prioritize and ship incremental releases, while setting up the behavior-first testing culture, the typed data-model architecture and the AI-assisted development workflow across the monorepo.

  3. Design system at scale

    Helped build and maintain a ~50-component design system used across multiple products — a shared contract that kept them consistent and shipping faster, not a component graveyard.
