Daniel Szeles

• I joined my current company as an intern during a challenging job market and quickly demonstrated initiative by contributing to an internal project using Java 17, Spring, and MongoDB. My main achievement was developing an endpoint to export teams and athletes during a campaign. While the initial requirement was to generate raw data for Excel import, I exceeded expectations by delivering a fully formatted Excel file, significantly improving usability and adoption.
• Subsequently, I contributed to several support and enhancement projects, including a Flyway-based reporting system where I introduced repeatable queries to streamline monthly reporting delivered via AWS S3 buckets. My ability to work independently and proactively led to a promotion to medior developer.
• For the past two years, I have been working on a flagship project. I started by addressing dependency vulnerabilities across multiple applications and am now responsible for maintaining over 15 repositories. I lead epics related to dependency management—coordinating resources, guiding implementation, and ensuring all libraries remain up to date. Within three months, my work helped eliminate the backlog of vulnerabilities, and I was recognized internally for this contribution. Alongside these responsibilities, I also handle bug fixes and complex code investigations. My current stack includes Java 17–21 and Spring.
• Recently, I have been expanding my skills by mastering Python as a secondary programming language and deepening my knowledge of databases and cloud technologies, particularly PostgreSQL and AWS.

I previously worked as a call center operator, consistently ranking among the top for positive customer feedback. This reflected my strong empathy, problem-solving abilities, and commitment to customer satisfaction. I also took an active role in training new team members, further demonstrating my reliability and leadership potential.

• Contributed to streamlined workflows by completing assigned administrative tasks in an organized and timely manner.
• Recommended products to customers, thoroughly explaining details.
• Responded to customer requests for products, services, and company information.
• Assisted customers by answering questions and responding to inquiries.

As a C# development intern, I primarily focused on backend tasks, but I also contributed to UI design and database work using SQL. I demonstrated a user-centered mindset by emphasizing usability rather than just quick solutions. I worked independently, asked the right questions to clarify goals, and ensured that my work aligned with both technical requirements and user expectations.
