Bachelor's Degree in Computer Science, Postgraduation in Data Science and Artificial Intelligence (in progress 2021/2022). Presently a Data Engineer, SQL Developer, and Senior Software Engineer with more than 18 years of hands-on experience in building SQL Databases and over 9 years of software development (C# and VB).Throughout my career, I have developed solutions for clients from different sectors: Clothing, Health, Car Rental, International Visas, Human Resources (HR), Finance, Tax, Accounting, among others. I am good as a team player who can also work independently, and one of my strengths is the ability to understand clients' needs.I have led Software Projects with SQL Server and .NET technologies (C# and VB), using Microsoft Project, with active participation in business analysis, requirements analysis, feasibility analysis, creation and maintenance of databases, systems development and maintenance, quality assurance, and validation tests.Recently, I built a Data-driven project in which I applied ETL techniques (Extract, Transform and Load) to tens of thousands of files (formatted and unformatted texts, spreadsheets, dBase database files, CSV, and XML files) to cross and validate them following Brazilian taxes obligations and rights. The result was a set of detailed reports and dashboards indicating missing documents and adjustments in taxes of 40 companies of the same group over the last five years, preventing fines up to R$ 33M (5 million Dollars).Another project to be highlighted was the development of an e-commerce platform (B2B and B2C) integrated with freight services (prices, terms, tracking, and delivery status), payment services (authorization and capture of credit cards, issuing and confirming payment of bank slips, and charge-back), a proprietary ERP system (automatic retrieval of products with stock, values, and information) and an electronic invoice system (NFe) of the Brazilian government. From the initial phase of business analysis, through development to implementation, the project lasted 2 years in which I had the opportunity of managing a small team of developers, and today the e-commerce is one of the most effective sales channels of the company.My specialties are related to problem-solving, focusing on customer service, using the best practices of systems analysis, requirements gathering, and project modelling. Also, database creation and management, being responsible for integrity and scalability, with great interest in Database Tuning techniques, aiming to increase the performance of complex queries.
