What I Do

  • πŸ“± Mobile Product Engineering β†’ I build polished, high-impact apps with React Native, Swift, and Flutter.
  • πŸ“ˆ Scale and Reliability β†’ I build for maintainability, performance, observability, and the realities of products used at scale.
  • πŸš€ Founding Experience β†’ I also have proven experience of taking ownership of products from concept to release, covering architecture, UX, testing, shipping, and iteration as a solo-engineer.
  • 🀝 Technical Leadership β†’ I help teams grow through ownership, mentoring, hiring, onboarding, and strong engineering standards.

Core Values

  • πŸ”„ Adaptability: I adapt well to different environments, whether that means the urgency of an early-stage startup or the rigor required by a product used at scale by millions of users. Working in both has strengthened my ability to learn quickly and perform consistently.
  • βœ… Ownership: I like being accountable for outcomes, not just implementation. That includes product quality, reliability, communication, and follow-through.
  • 🧠 Clarity: I value staying composed, reducing noise, and making good decisions when urgency is high.
  • πŸ’™ Respect: I care about building things that are useful, intuitive, and trustworthy for the people depending on them.

Selected Highlights

  • Built mobile products from zero with full ownership across UX, implementation, QA, shipping, observability, and iteration.
  • Worked across both early-stage and more mature product environments, and increasingly focused on the challenges that come with scale, reliability, and operational quality.
  • Bridged React Native with native Swift and Kotlin SDKs through custom modules when off-the-shelf integrations did not exist.
  • Shipped complex mobile capabilities including turn-by-turn navigation, background uploads, in-app communication, OTA updates, and live activities.
  • Improved products by combining direct user feedback with observability, monitoring, and a strong awareness of how usage changes at scale.
  • I bring engineering depth shaped by startup ownership, while leaning strongly toward the needs of larger products, scale, reliability, and long-term quality.
