What I'm looking for

I seek a role where I can apply data analysis and IT skills to improve operations, learn from experienced teams, and contribute measurable results in a collaborative environment.

I am an IT/Data Analyst with practical experience implementing POS systems, preparing sales and financial reports, and performing QA functional testing for web systems. I combine technical skills in SQL, Excel, and data management with strong analytical and communication abilities to support operational decision-making.

My background includes roles in retail operations, assistant management, and broadcasting technical assistance, where I monitored inventory, controlled expenses, scheduled programming, and supported advertising campaigns. I contributed to smoother transactions, organized daily sales data for management, and created user-focused documentation and video manuals.

I am committed to continuous learning and professional growth, holding certifications in Python, social media marketing, and UX foundations. I seek opportunities to apply my problem-solving mindset and technical proficiency to help teams improve processes and deliver measurable business results.
