If you'd like to book a free 30-minute mentoring session with me, check out my ADPList profile: https://adplist.org/mentors/harold-park?session=55649-mentorship-session-for-entry-juniors Struggling to break into tech in this tough job market? Feeling stuck in your job search and overwhelmed by imposter syndrome? Or perhaps you're looking for guidance on navigating a toxic workplace? 🤔 You've come to the right place. 🚀 Hi, my name is Harold, and I’ve been developing websites and web applications professionally for over 7 years across diverse industries, with a focus on front-end development. Like many of you, I come from a non-traditional background. I was on the path to pharmacy school, then a teaching credential, before discovering coding. I attended an intensive three-month, in-person JavaScript boot camp. After a tough job search, I finally landed my first opportunity through an internship. Having gone through a similar journey that you are about to embark on, I firmly believe that, with time and dedication, you too can break into tech. 💪 I find deep fulfillment in helping others. I can support you with industry insights 🌐, pair programming 🤝, code reviews 📝, capstone project planning 📊, and job search strategies 📈. As a former teacher and mental health advocate, my mentoring approach is rooted in empathy, the Socratic method, and constructive feedback. My goal is always to adapt to your unique learning style and the problems you’re facing, bringing an objective lens rather than enforcing my own opinions. After all, coding can be intensely subjective, and the best solutions come from collaboration and knowledge transfer. I look forward to meeting you and wish you the best on your tech journey 🙂
