Built full-stack applications for clients across multiple industries. Learned to be versatile, communicate effectively with stakeholders, and deliver consistently.

Co-founded a real estate tech startup where I:

• Built engineering team from ground up
• Architected entire platform from concept to production
• Made all technical decisions (stack, infrastructure, architecture)
• Worked directly with investors and board on technical strategy
• Learned to balance startup speed with engineering quality

Leading frontend engineering at YellowBird:

• Managing team of frontend engineers
• Driving React/TypeScript technical excellence
• Improved performance, established best practices, mentoring team members
• Hands-on coding while providing technical leadership

Building full-stack mobile applications concurrently:

• Creating cross-platform apps with React Native (Expo)
• Architecting backends with Supabase (PostgreSQL, Auth, Realtime, Storage)
• Delivering complete solutions from database design to mobile UI
• Maintaining cutting-edge full-stack and mobile development skills

• 🏗️ Frontend & Mobile Architecture
• 📱 Cross-Platform Mobile Development (iOS + Android from single codebase)
• 🗄️ Full-Stack Development (React Native + Supabase)
• ⚡ Performance Optimization (Web & Mobile)
• 👥 Technical Leadership & Team Building
• 🔧 Developer Experience & Tooling
• 🌐 Responsive & Accessible Applications
• 🧪 Testing & Quality Assurance

Most senior engineers have deep technical skills. I bring that plus:

• CTO Experience: Strategic thinking about technical decisions from a business perspective
• Active Full-Stack: Not just past experience - currently building React Native + Supabase apps
• Web + Mobile: React for web, React Native for mobile - complete cross-platform capability
• Proven Leadership: Built engineering teams and culture from scratch
• Full Context: Understand the entire stack from database to mobile UI
• Battle-Tested: Navigated startups, scaling challenges, and leading teams through uncertainty
