Characterized by fostering discussions on best development practices and cultivating a culture of continuous improvement within the team.I take immense pride in my track record of delivering defect-free functionality, a testament to my meticulous attention to detail. Additionally, I actively engage in technology knowledge sharing, ensuring that my team stays up-to-date with the latest advancements in our tooling. Worked closely with quality assurance teams to swiftly identify and resolve issues.Furthermore, my expertise in optimizing SQL queries, JavaScript, and C# code has played a pivotal role in significantly improving system performance. I'm excited to take on new challenges and continue contributing to innovative projects in the future.

Performed debugging operations on CMS platforms like WordPress, built new CMS solutions from scratch, migrated several processes, services, and API endpoints from Azure VMs into Azure Functions, and developed cloud-based solutions, optimizing scripts to import and handle data into Cloud SQL.Also, I used Google Cloud Platform and the Speech API on a list of recorded calls daily, automating processes that were previously completed by hand.Collaborating with various clients from multiple countries, I proposed and implemented optimized solutions for database management, Virtual Assistant, or Captcha integration, scoring 100% Job Success that earned me the Top Rated Plus badge.

Used C#, ServiceStack, Redis, Elasticsearch, and Sphinx to develop new features into a real-time bidding/ad exchange distributed system, performed 3rd party integrations with multiple APIs, and developed a distributed data hydration service that pulls data from druid tables and injects information from MySQL into Redis to quickly access the information from any device or environment.Enhancing user interfaces by developing new Angular-based components, I also build Go-based modules after a successful collaboration with various developers that took place by using modern pair-programming techniques.Also, I pulled in insurance policies and advertising business metrics into the company’s databases using AWS (Lambda, S3, RDS), Java, Maven, and Spring, by developing several ETLs that interacted with external APIs through secure channels and authentication methods.

Actively involved as a Customer Service Representative for Walmart.com’s phone account, being temporarily nominated as a supervisor due to exceptional results in the previous role.Also, I developed business metrics reports in Excel for internal use that helped in taking rough and decisive decisions to ensure continued stability and a high-performance level.

Created and presented a Social Media action plan that generated expected results, ported the backup system for the current Enterprise Content Management System to a secure external server using the Bash scripting, and developed SQL Server and PostgreSQL databases using modern optimization concepts that helped in serving data faster, facilitating their maintenance and future extension.I was also involved in addressing the needs of doctors from the Guatemalan Stomatological School by developing and implementing a friendly and engaging internal website that responds to the client’s requests in a highly secure and scalable environment.

Maintained Linux servers, designed and developed various scripts using Python, Bash, and Perl to solve business problems, and also debugged Java-based applications, ensuring that the access to classes is handled using the security manager.Working with tons of data, I managed Oracle databases by modifying data and writing procedures to capture and deliver information as requested.Also, I collaborated with various institutions, offering support to EBT, ECC, and EPC systems for the Government Solutions division, proposing ideas that were quickly adopted and put into practice.

Extended and developed new Joomla components that ensured a stable connection between the website and the main system database, letting customers verify, control, and update their information in real-time.Also, I implemented the Alfresco Enterprise Content Management System to store insurance policies, payment slips, customer documentation, and other documents, as well as developing and implementing a temporary email server due to unexpected failures caused by the main one.Performing analysis and optimizing workflows, I improved the requirements tracking system from the IT department by implementing an Action & Information Management System OneOrZero, as well as developing a highly-responsive instant messaging system, combining Spark and OpenFire to handle internal communications better.

Built applications and technical solutions using Delphi, implemented GUI software and created SQL Server and PostgreSQL databases using indexing, triggers, and other components to enable faster access for data.

Provided technical support for multiple customers, maintaining computers both from a hardware and software perspective to ensure that every device works as expected.
