Senior Full Stack Engineer

Seasoned Senior Software Engineer, with a background in full-stack development and a knack for leading technical teams. I thrive on transforming complex challenges into efficient, scalable software solutions, particularly within the e-commerce space. My toolkit is packed with PHP, React, MySQL, AWS, and Docker, among others, and I'm adept at everything from wrangling legacy code to integrating third-party APIs.
In my recent role as a Senior Software Engineer and Technical Lead, I guided a team in enhancing a major e-commerce platform, focusing on significant projects like migrating from PHP 7.4 to 8.2 and modernizing our React frontend from class-based to functional components. These weren't just make-work projects; they boosted system performance, security, and maintainability. I've also got a track record of directly impacting the bottom line, like implementing a referral program that bumped repeat business by 20% and optimizing database queries to slash execution times by 30%. My experience includes developing webhook-based, event-driven architectures and ensuring robust data security with role-based access controls.
Beyond corporate environments, I've got entrepreneurial blood. I successfully built a reservation system for Dog Sled Rides of Winter Park that shifted 98% of bookings online and implemented a dynamic pricing algorithm that jacked up the average sale by 20%. For Mountain Dawg Outfitters, I developed a cloud-based POS with integrated inventory and CRM, automating everything from customer receipts to vendor orders, which drastically cut admin costs and ordering times.
I hold a BS in Engineering & Applied Science from Caltech, with a focus on computer science. I'm passionate about leveraging technology to solve real-world problems, mentoring fellow engineers, and continuously diving into new challenges. Whether it's building something from scratch or optimizing existing systems, I'm all about delivering value and driving growth.
Open to discussing new opportunities where I can bring this blend of technical expertise and business-focused problem-solving to the table.
