About

Team leadership, development, and production support.

Currently a Software Engineering Team Lead at EY, with 8+ years of engineering experience across application development, automation, delivery, and production support.

I turn business requirements into technical plans, coordinate delivery with business analysts and product owners, maintain documentation, and communicate progress to stakeholders. I also conduct technical interviews and lead onboarding for new joiners.
