    Hi and thanks for checking out my profile! I offer services in web analytics, safe personal blockchain usage, digital worklife optimization and in the other skills mentioned on my profile. I have worked in the analytics industry (web primarily) for 15 years and I know everything about setting it up technically, with numbers that you can trust. I prefer long term collaborations. Projects I find especially interesting currently are server side setups and consent setups but I can do most of everything, especially when it comes to the google products like ga4, google ads, tag manager and data studio. Regarding blockchain I stake ethereum and invest in bitcoin as well as doge. I know in-depth about how to keep your funds secure with your own mnemonic, seed and keys. I know how to store them, how to use them safely (offline signing) in multiple ways (hardware keys or other offline software) and can advice on how to share them with your trusted relations if relevant. As for digital worklife optimization I find it super useful to optimize and help both our professional as well as our personal life, with different IT software and processes which are relevant to each of us individually. Speaking about myself, it is the to-do lists, shopping lists, calendar, SMS texts as reminders, emails and much more. I will love helping you improve your setup and to a minimalistic one, that is easy to maintain and develop. Looking forward to collaborate with you! Simon

Diverse Freelance Experience Transitioning into freelance work as a software developer, I embraced a wide range of technologies. From building Shopify apps to developing custom APIs and solutions for large corporations, my freelance career broadened my technical expertise and adaptability. Current Endeavors Today, I am the co-founder and solo developer of Trendbook, a creator commerce platform that empowers content creators to share their outfits and earn commissions from sales.
