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. Through this mentorship, I've gained insights into different learning styles and challenges, which has further enriched my own engineering practice and approach to problem-solving.

Easy 🙂 **Backstory** I started programming in 2018 after my mentor told me that it really fits the way I think. Before I started I was learning marketing, working in Facebook Ads and Shopify Stores (with Google Analytics, VWO, and other website optimization softwares), I was more interested in automation, and building to do tasks only once. I started at first learning Python for automation (which is still my primary language and what I really enjoy coding in). Eventually, I learned that by itself, Python isn't that sharable if you want other non-coders to use the my apps, so I grew my way into web development, diving deep into Django, HTML & CSS, building multiple sites with only those to get experience, for example: - My website: https://www.zackplauche.com/ - A mini app I built: https://www.dollarperhourcalculator.com And more :) Then eventually learning JavaScript and the Vue.js framework to take my websites, designs, and User Experiences to the next level, building at first simple apps like my DollarPerHour Calculator (https://zackplauche.github.io/DollarPerHourCalculator/), and more advanced ones, like the current one I'm developing (still in progress, but it's the biggest app I've ever build, using both Vue.js and Django). I've been teaching programming since 2019, and my students have loved me. I have students I work with that have been working with me weekly since I first started (more than 5 years now!). They helped me keep both my coding and teaching career sustainable as I was helping them with their issues, training them to be effective developers, starting my own software agency, and building my own apps. I'm extremely grateful to my students and truly care about and do my best to support their success in whatever their endeavors.

I have been helping multiple companies since 2008. So probably somewhat qualified to answer the same. Being a code mentor, I will have the opportunity to get involved in different technical challenges that I really love. Next, I'm usually pretty good at answering odd questions.
