What I'm looking for

I want to lead engineering teams to deliver scalable web/mobile systems, improve performance and SEO, and optimize cloud costs—while maintaining strong code quality, security, and measurable delivery through team OKRs.

I’m an Engineering Manager with 14+ years of experience designing and developing scalable web and mobile systems, leading high-performing teams, and optimizing cloud infrastructure. I’ve been recognized with multiple Awards of Excellence, including for reducing costs, improving SEO, and delivering business-critical features.

In my current role, I migrated 90% of a monolith architecture to serverless, reducing AWS server costs by 50%, while managing a 20-person engineering team across multiple squads. I’m focused on execution quality—ensuring performance, security, and code quality—using workflow improvements like GitHub Actions and integrating business-critical third-party providers and platforms.
