👤 About Me

Josiah Lamuel Rosell

I am a Computer Science student at De La Salle Lipa; passionate about software development, digital solutions, and communication- focused technologies. I enjoy building projects that balance technical depth with clarity, usability, and real-world impact. Beyond coding, I value clear communication, thoughtful design, and the ability to translate complex ideas into accessible solutions.

I believe technology isn't just about code — it's about creating tools that can help people, tell meaningful stories, and solve real problems. I carry a mindset of continuous and consistent learning, curiosity, and purpose in everything I build.

Open to internships, mentorships, and collaborations that create real-world impact through technology..

Financial Challenges and Coping Mechanisms Among Filipino Parents of Grade 11 Students
Published on International Journal of Academic Multidisciplinary Research (IJAMR)February 2023

This research paper employs a qualitative design to explore the financial difficulties and coping strategies of Filipino parents of Grade 11 students in Bulacan, Philippines. Through semi-structured interviews and thematic analysis, the study identifies key challenges such as low income, high cost of living, and limited resources. It also highlights common coping mechanisms like budgeting, saving, and side hustles, while noting the significant stress and anxiety parents experience. The study concludes by recommending policy interventions, financial literacy programs, and community support to better assist these families.
