With over five years of experience in health logistics management systems, HealthTech, and EdTech, I specialize in developing cloud-based applications. I've participated and led key roles in large projects, optimizing processes, server management, and system performance for efficiency. Aside being experienced as a hands-on engineer, I have had the priviledge of teaching and mentoring a few tech enthusiasts helping them develop their enthusiasm into full technical proficiency and professional growth. It has been rewarding to see their passion evolve into tangible skills and career achievements, and witnessing their development has reinforced my own understanding and appreciation of the field.
