Hi, Hallo, Grรผezi, Sascha here ๐ As an experienced online business strategist running my own business (Niavimi Oร) since 2019, I have not only been creating all my own websites, landing pages, and online sales funnels by myself over the years, I have also had the pleasure of working on various client projects.
My expertise is online sales funnels, email marketing automation, affiliate marketing, online course configurations, AI voice-over and text-to-speech (TTS) generation, and the Estonian e-Residency.
For years I used ClickFunnels and AWeber, but in 2023 I switched my entire business over to Systeme io, which is much more user-friendly, more modern, faster, and drastically more cost-efficient.
Instead of using a traditional website that doesn't convert your visitors into buyers, your business needs online sales funnels.
Let's get your Systeme io setup ready for your success so you can build and grow your customer base and increase your sales.
Whatever your needs are, get in touch and let's build your success. We can get it done.
โข Landing / Squeeze / Bridge / Thank you pages
โข Sales / Order form pages
โข Order confirmation / Offer wall pages
โข Order bumps, upsells downsells
โข Automation rules and workflows
โข Email campaign setup
โข Online course / Community setup
โข Integrations (e.g. scheduling, payment, automation, ...)
โข Tracking pixels setup
โข Custom code (e.g. on-page navigation, LottieFiles, etc.)
โข Migration help
โขโขโข
As a native German/Swiss German speaker, I have also assisted numerous clients in transcribing their videos and working on a variety of challenging other projects.
These include a 42-minute corporate interview with 4+ speakers conversing in a combination of Swiss German, German, and English, as well as a 16-minute street interview with the same mix of languages and heavy use of slang.
Additionally, I've helped clients with the translation and proofreading of short to medium-length texts, spanning various topics, including private and business correspondence, emails, and website content.
โข I will proofread your text in English or German.
โข I will translate and localize your text in English, German, or Swiss German.
โข I will transcribe your audio or video file in English, German, or Swiss German.
I also tutored German online for 6 years. Being a language and tech nerd with an aptitude for fast learning and someone who lived abroad for nearly a decade, I'm always eager to take on new challenges and expand my skill set.
As I like to say, "Change is permanent. Growth is a choice."
Please check out my project offerings below and let's chat to build your success together and get your questions answered.
