👩‍💻 About Me | Behind the Tech

I am driven by technology that combines data, cloud systems, and IT infrastructure to deliver solutions.

This combination allows me to understand how data is collected, stored, processed, and analyzed while also seeing how servers, networks, and cloud platforms support these operations. Whether I am analyzing datasets in Python, writing SQL queries, configuring Windows servers, exploring Microsoft Azure, or reviewing network diagrams, I am motivated by solving practical problems through technology.

Technology excites me because it provides solutions to real-world challenges. Data allows us to uncover trends and make informed decisions. Cloud computing enables scalable and reliable solutions that reach users everywhere. Networking and infrastructure form the backbone that keeps organizations operational. Cybersecurity ensures these systems remain safe and resilient. Together, these areas create a solid foundation for a well-rounded IT professional, which is the path I am committed to pursuing.

From a technical perspective, I work with Python, SQL, Power BI, PostgreSQL, MySQL, HTML, CSS, JavaScript, Linux, and Windows Server. I am also familiar with cloud platforms such as Microsoft Azure, Amazon Web Services, and Google Cloud Platform. For data exploration and learning, I use Jupyter Notebook, Anaconda, Excel, and Kaggle. On the infrastructure side, I have experience with Active Directory, DNS, DHCP, Group Policy, virtualization basics, and network configuration using Cisco concepts and Packet Tracer. This combination allows me to develop both technical depth and practical versatility.

Professionally, I aim to grow into roles including Data Analyst, Cloud Engineer, IT Support Engineer, Network Technician, or Systems Administrator. I thrive in environments where I can contribute knowledge, deliver practical solutions, and continue developing as a versatile professional. I value teamwork, problem-solving, and reliability, and I strive to bring a positive and professional attitude to every task.

I approach technology with a strong sense of responsibility. Systems need to be secure, data handled ethically, and networks maintained reliably. My interest in cybersecurity sharpens my focus on safety and resilience, encouraging me to consider technology not only for functionality but also for protection and continuity. I enjoy the creative side of technology, whether it is writing code, designing dashboards, connecting servers, or configuring cloud services and feeling that sense of accomplishment.

Continuous learning is central to my professional growth. I take online courses, practice on various platforms, explore documentation, and learn from hands-on projects. I break complex concepts into simple steps and celebrate milestones along the way. Overall, I see myself as a curious, disciplined, and dedicated professional, eager to use data, cloud platforms, and networking expertise to create secure, scalable, and impactful IT solutions.
