Projects
Volunteer Work
Homebuilder GK
We worked closely with local leaders and community members to erect sustainable, disaster-resilient homes for over fifty displaced families following the recent typhoons. This initiative wasn't just about mixing concrete and laying bricks; it was a deeply collaborative effort focused on restoring dignity and hope. Volunteers from all walks of life gathered on weekends, dedicating countless hours to painting walls, assembling roofing structures, and ensuring every new home met strict safety standards. The joy on the faces of the new homeowners during the turnover ceremony was an unforgettable reward.
Coastal Cleanup Drive
The annual coastal cleanup drive brought together hundreds of enthusiastic volunteers dedicated to preserving our fragile marine ecosystems. Starting at dawn, our team combed the shoreline, meticulously removing tons of plastic waste, discarded fishing gear, and other hazardous debris that threaten local wildlife. Beyond just picking up trash, we conducted detailed waste audits to help researchers track pollution sources. This massive collective effort significantly restored the natural beauty of the coastline while fostering a strong sense of environmental stewardship among the participants.
Campus Support - Greeter, Wayfinder and Event Support
Served as an ambassador of UCalgary and the GCEC conference and a friendly face GCEC delegates meet. Tasked with greeting and welcoming guests to the University of Calgary and to GCEC 2025. Conference attendees asks general questions regarding the Conference Sessions, Events, Campus, etc.
Youth Tech Mentoring
Recognizing the growing digital divide, we launched a youth tech mentoring program aimed at empowering high school students from underprivileged backgrounds. Over the course of six months, our dedicated team of industry professionals taught foundational programming concepts, web development, and essential digital literacy skills. The curriculum was highly hands-on, culminating in a hackathon where students built and presented their own functional websites. Watching these brilliant young minds transition from tech novices to confident creators has been incredibly inspiring and rewarding.
