I excel at technical leadership through architecture - creating reusable systems that accelerate team velocity and leading by example in code quality. I've guided engineering teams of up to 12 developers through complex technical challenges, designed component architectures that reduced development time by 70%, and built systems processing millions of users.
My approach combines deep technical expertise with mentorship - I solve the hardest technical problems while empowering other engineers to master complex systems and scale their impact.
