Accedo Digital Inc. | Sep 2019 - Jan 2020

Digital Marketing Strategist

As a Digital Marketing Strategist, my primary objective was to design and implement effective digital marketing strategies for a diverse portfolio of small and medium-sized businesses across the United States. From family-owned establishments to car dealerships, and even a prominent Beverly Hills plastic surgeon, I worked with a wide variety of clients with unique needs and goals. In addition to my core responsibilities, I supported the sales team by conducting marketing plan audits for potential clients, identifying areas for improvement, and offering solutions to enhance their marketing efforts. I also played a key role in negotiating strategic alliances with other marketing agencies, which resulted in successful partnerships and expanded our white- label services. Thanks to my efforts, we were able to improve most of our key performance indicators, earning recognition and accreditation as part of the renowned Google Partner program.

Accedo Technologies | Jul 2018 - Sep 2019

Legal Assistant

Started as a remote legal assistant for a Houston-based Legal Firm involved in mass tort litigations against manufacturers of faulty medical devices and potentially harmful agrochemicals. In this role, I conducted phone interviews with clients to gather essential information about their claims to assess their eligibility. If a client qualified, I opened a request for their medical records, ensuring HIPAA compliance, as evidence to support their claims. After approximately six months, I got promoted to a senior legal assistant role where my primary responsibility was obtaining any missing information needed to file a case. In my docket, most of the time we would be missing the pathology report (a key piece of evidence), so I spent most of my time in communication with hospitals and laboratories until I was able to obtain a copy of this document. Lastly, I also provided support to junior legal assistants whenever needed.

White Shark Media® | Jun 2016 - Jan 2017

PPC Strategist

My role as a Pay-Per-Click Strategist involved managing a diverse portfolio of roughly 28 small to medium-sized businesses operating in different industries throughout the United States. One of my key responsibilities was to create and manage search engine marketing campaigns on both Google and Bing platforms, with the aim of boosting brand visibility and driving conversions.

Cargill | Mar 2015 - Jun 2016

Procurement Analyst & COE Analyst

Responsible for fulfilling the sourcing of supplies, equipment, repairs, and capital expenditure projects to keep production going smoothly and safely. That meant sourcing locally and internationally to find the best deals for each requirement while making sure we followed company policies and kept costs down. A few months into the purchasing analyst role I was offered the added responsibility of center of excellence analyst for the Nicaraguan procurement department. Under this new assignment, I was expected to work 50% as a purchasing analyst and 50% as a COE analyst. During my time as a Center of Excellence Analyst (COE), I handled a variety of important administrative duties for the Procurement Department in Nicaragua. These responsibilities included managing databases, data analysis, reporting, calculating key performance indicators, screening potential new suppliers, and more.
