Hi There,
I understand you want to manage Adwords account to improve efficiency & traffic I can help help you with Adwords Optimization like - keywords expansion, negative keywords, audience targeting, custom affinity, bid adjustment on device, keywords, audience, ad schedule, locations etc with Google best practices to improve quality score/rank.
I got real time experience on Adwords optimization process, as I worked for Google (as a vendor) on optimization process.
Let me know if any points.
