Hi! I’m a dedicated and driven 4th-year BS Mathematics student, graduating this August. I’m eager to start applying my knowledge and training in real-world projects whether it’s in data analysis, academic writing, problem solving, or anything that requires logical thinking and precision. Throughout my studies, I’ve developed strong skills in mathematical reasoning, statistical analysis, and critical thinking. I’m comfortable with both numbers and words, and I thrive on solving problems efficiently and accurately. I may be new to Upwork, but I bring a strong work ethic, a learner’s mindset, and the determination to deliver quality work every time. If you’re looking for someone reliable, responsive, and committed to learning and growing, I’d love to work with you. Let’s collaborate!
