Brian Kelly

I’m a senior full-stack engineer with 10+ years of experience building scalable, high-performance web and mobile applications for startups and enterprise teams. My core strengths are Angular, React, React Native, TypeScript, Node.js, and AWS, with a strong focus on frontend architecture, system reliability, and performance optimization.

I’ve led and owned complex platforms end-to-end, often stepping into senior technical roles where clarity, structure, and long-term maintainability matter most. I’m known for acting as the “brains” behind frontend systems—defining standards, guiding implementation strategy, and mentoring developers—while still coding hands-on when it drives the most impact.

Across my work, I’ve delivered measurable results: improving application performance by up to 40%, increasing user engagement by over 30%, cutting deployment times by more than 50% through CI/CD automation, and reducing downtime by modernizing cloud infrastructure. I’ve built real-time systems, data-driven dashboards, mobile apps, and SaaS platforms used by thousands of users.

I bring a product-minded approach to engineering, working closely with designers, product managers, and backend teams to turn business goals into intuitive, reliable user experiences. I value clean code, thoughtful architecture, and clear communication, and I thrive in remote, distributed environments.
