What I'm looking for

I want to work in the technology industry where I can lead product and solution delivery, drive digital transformation, and support telecom customers through agile execution, KPI/OKRs, and strong commercial and contract outcomes.

I’m a Product Manager with 12+ years of experience in product, project, and account management across technology and telecommunications. I lead technology solutions end-to-end—from product lifecycle management and customer enablement to execution of large-scale project plans—while keeping commercial outcomes front and center.

In my recent roles at Huawei, I supported telecom operators serving up to millions of users, analyzing customer feedback and usage data to optimize product performance and adoption. I also led tender processes and built technical, financial, and commercial proposals, delivering approximately USD 26M in annual revenue and supporting accounts generating over USD 40M annually.

I’m known for combining strategic vision with agile execution—aligning KPI/OKRs, forecasting, and contract negotiation with cross-functional delivery. From platform troubleshooting in Linux environments to service operations improvements and training, I bring a hands-on, customer-focused approach that strengthens stakeholder relationships and improves customer satisfaction.
