I've coordinated commercial outreach, proposals, investor communications, and technical teams at PROESAL Green Energy Plus, helping secure $125,000 in capital and advance requirements for a 5-MW Power Purchase Agreement.

I also supervised 40 electronic solar-palm installations, from excavation and concrete bases through operational installation, while coordinating materials, trade teams, paperwork, and quality follow-through.

Across remote support roles with Hewlett-Packard, Boost Mobile, MoneyGram, Capital One, and Sprint, I've resolved technical issues, managed escalations and live chat, supported retention and sales, and translated complex details into clear next steps in Spanish and English.
