BSc. (Hons) in Information Technology, Geophysical Engineer, and MSc in Petroleum Geosciencewith strong mathematical, problem-solving, and analytical skills. I'm currently particularly interested in Data Analytics and Software Development.

Proficient in multiple programming languages, including Python, Java, JavaScript, SQL, and R. I have a huge interest in Machine Learning and Natural Language Processing. I've been recently working in areas such as Text classification and Sentiment Analysis. I have solid knowledge in several ML algorithms (Naive Bayes, Decision Trees, K-Nearest Neighbour) and in Time Series Analysis. I have experience working with Python (Pandas, NLPTK, Scikit-learn, SciPy, Plotly, TextBlob, Vader Sentiment), R, and RapidMiner.

Solid experience in Object-oriented programming and Web Development. I have developed several projects using Java, Python, React, Node.js (Express.js), and Dash.

I also have advanced experience with Linux (including Shell Scripting) and I have worked with Relational databases (SQL, MySQL, PostgreSQL) and Cloud computing (AWS and Google Cloud).

Senior Business Development Executive

I am responsible for creating new sales prospects and carrying out b2b outgoing calls to prospective clients. Additionally, I prioritize staying well-informed about each customer's current and future business practices and processes, allowing me to build and maintain strong relationships with them.

Building and maintaining a professional relationship with IT Managers is a key part of my role. This enables me to identify their needs and next investments. The gathered information is required by our clients (Largest Tech Companies) and used in the next step of the sales process.

  • I work in different markets and contact clients in French, English, and Spanish: France, Belgium, Luxembourg, Spain, Middle East, and Africa.
  • Gathering client details and Maintaining/Updating IDG database with accurate client details.
  • Train new team members and provide ongoing training:
  • Motivating, developing, and training staff at a BANT level.
  • Script delivery and how to effectively communicate.
  • How to construct specific campaign questions that encourage the prospect to expand on information.
  • Monitoring team members on a daily basis, providing support and encouragement where necessary to ensure all service levels and KPIs are reached.
  • Ensure Key Performance Indicators (KPIs) are met and constantly improved.
  • Collaborating with the Team Manager in the recruitment process of new agents.
  • I have experience leading campaigns. Liaise and work closely with the Client Manager, Team Leaders, and all key stakeholders involved in the team set-up.
