Monika Tenšić

Monika Tenšić

Born in 1994 in Varaždin, I’m a senior frontend engineer with a strong focus on clean code, team collaboration, and building sustainable software. I started my academic path in mathematics, but discovered a passion for programming and shifted to the Faculty of Organization and Informatics, where I found the perfect fit between theory and practice.

During my first year of graduate studies, I began working at Emil Frey Digital as an iOS developer. As the company’s focus evolved, I transitioned to frontend development with Angular — a path I’ve followed ever since. I spent 3.5 years honing my skills there. Over the years, I’ve worked across several roles and companies: as a Product Owner at Porsche E-Bike Performance (formerly Greyp), as a Senior Angular Developer at Endava, and as a Teaching Assistant at the Faculty of Organization and Informatics (a role I continue to hold). In April 2024, I returned to Emil Frey Digital to apply my broad experience and lead key projects.

My core interests include writing clean, maintainable code, improving developer workflows, and helping teams grow through better communication and feedback. I believe that great code is built by great collaboration — and that learning to give and receive feedback well is one of the most valuable skills a developer can develop.

When I’m not coding, you’ll often find me behind a camera lens or building intricate LEGO sets — two hobbies that fuel my creativity and attention to detail.

This venture evolved into Net Nerds in 2014, a brand that became synonymous with cutting-edge technology services, including networking, web design, and cybersecurity. At the same time, Dean’s passion for teaching led him to found WeTeachTechnology.com in 2009, empowering individuals and businesses to navigate the fast-changing digital landscape with confidence.

In 2018, Dean anticipated the transformative potential of artificial intelligence and launched WeTeachAI.com, a platform designed to help businesses and individuals embrace AI and integrate it into their operations. Building on nearly three decades of experience, he expanded further in 2022 with ITeachAI.com, offering private consulting tailored to help clients maximize their technological potential in an ever-evolving world.

\\Konzepterin und Moderatorin für Themen der Nachhaltigkeit in Bildung, Kultur und Zivilgesellschaft\\

Als selbständige Diskurgestalterin für die sozial-ökologische Wende und Nachhaltigkeitsmanagerin mit Schwerpunkt Programmatik in Bildung, Kultur und Zivilgesellschaft habe ich viel erforscht, beobachtet, gelernt und verstanden. Meine breite Praxiserfahrung in der Konzeption und Kuration von Bildungs- und Veranstaltungsformaten hilft mir, drängende gesellschaftlichen Fragestellungen mit Workshops, Beratung und Konzeptionen nach nach vorne zu bringen. Ich arbeitet mit Teams an passgenauen transformativen Diskursformaten und nachhaltigem Wissensmanagement, berate und moderiere Prozesse und leite durch eventbasierten Austausch.
Angesichts multipler globaler Krisen, fokussiere ich seit einigen Jahren auf drängende sozial-ökologische Transformationsvorhaben: Postwachstumsökonomien, Umwelt- und Naturschutz, eine nachhaltige Digitalisierung, lebenswerte Städte, Mobilitätswende ... all diese Bereiche (und noch viel mehr) müssen in die öffentliche Wahrnehmung. Dabei steht die Frage im Mittelpunkt, wie Austausch und gemeinsames Lernen in und für die Transformation gestaltet sein müssen, wie soziale Kipppunkte (im positiven, transformativen) Sinne erreicht und gleichzeitig der demokratische Diskurs gestärkt werden kann: systemisch, feministisch, diskrimierungskritisch und empowernd. Neue Formate zu erproben und nicht immer alles so zu machen wie immer schon, ist mir zugleich Herausforderung und Vergnügen!

Ich lebe seit vielen Jahren in Berlin, bin berührt und inspiriert von der Klimabewegung, Openeverything und einer Kultur des Teilens. Vor meiner Tätigkeit als selbständige Diskursgestaltung war ich fünf Jahre als Innovatorin und Projektleiterin der politischen Medienbildung bei mediale pfade tätig. Ich bin Teil der Bits & Bäume Bewegung und Co-Kuratorin der re:publica.

Mandy Lile

Mandy Lile

Potency is defined as “The power of something to influence or make an impression” which is what Potency No. 710 is setting out to achieve.

When Aesthetician Mandy Lile created Potency No. 710, she was already working with plant based ingredients some 20 years, but she became very intrigued by the mystery of what she felt may be the long lost secret ingredient in skincare, cannabis. After embracing cannabinoids like CBD and CBG in her product formulas, and seeing the results and abundance of testimonials, the answer was revealed, and Potency No. 710 has been disrupting the skincare scene with cannabinoid skincare products since 2018.

Since childhood, Mandy has had a gift for taking an ugly situation and making it beautiful. Unfortunately,thanks to draconian cannabis prohibition, her late father spent 15 years incarcerated on cannabis charges encapsulating much of her childhood. This is, without a doubt, something that fuels her fire to change the stigma surrounding this plant, and she is doing so through beauty.

Since opening her first skincare clinic at the age of 20, Mandy has gained a plethora of firsthand knowledge on the importance of safe ingredients. It is this force and the intentions that she puts into the products Potency offers that stand them apart from the rest, making it more than a brand but rather a lifestyle—a lifestyle of self-care powered by nature and higher intentions.

From hometown high school pals to celebrities, Potency No. 710 products are being embraced by thousands of people around the globe. In honor of the ones that have supported her along her journey, Mandy loves to give back through various philanthropy efforts. She is the sponsor of many small events, businesses, and organizations not only in the cannabis culture but in her local community as well.

Mandy works with several causes including the following.

 Watts Community Core
 Cannabis for Children International
 Women Empowered in Cannabis
 Cannabis Spa Association
 Cannabis Physicians Association

Mandy along with her Fiance’ Harry are the owners of 2 dispensaries in Needles California, H Street Patient Care and The Bud Farmacy. Both of these dispensaries are vertically integrated and have been serving Southern California and the surrounding areas for over a decade!

Mandy’s story and Potency No. 710 products have been featured in a variety of publications including Allure, Medium, Modern Luxury, Hello Giggles, Elevated Lifestyle Magazine, Vanilla Plum, Refinery 29, The Social NY, and many others
