Hi, Hallo, Grรผezi, Sascha here ๐Ÿ‘‹ As an experienced online business strategist running my own business (Niavimi Oรœ) 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. โ€ข Landing / Squeeze / Bridge / Thank you pages โ€ข Sales / Order form pages โ€ข Order confirmation / Offer wall pages โ€ข Order bumps, upsells downsells โ€ข Automation rules and workflows โ€ข Email campaign setup โ€ข Online course / Community setup โ€ข Integrations (e.g. scheduling, payment, automation, ...) โ€ข Tracking pixels setup โ€ข Custom code (e.g. on-page navigation, LottieFiles, etc.) โ€ข Migration help โ€ขโ€ขโ€ข 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. โ€ข I will proofread your text in English or German. โ€ข I will translate and localize your text in English, German, or Swiss German. โ€ข 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. โ€ขโ€ขโ€ข What others say... "Sascha was wonderful to work with. He took my website ideas and quickly executed. He was a joy to communicate with, was highly professional, and went above and beyond to help me build my Systeme io website. He used custom code to help me add a video to my Home page, a custom form to my Contact page, and a few other things. Both the quality of his work and Sascha as a professional made this project smooth and seamless, and I would definitely recommend his services." "I had the pleasure of working with Sascha, who created AI-supported voice-overs for my project. From start to finish, I was impressed by his professionalism and expertise. Not only did Sascha deliver top-notch work, but he also supported me throughout the entire process with extraordinary dedication and outstanding performance." "Sascha is a pleasure to work with, he deeply understands languages and sends great information about his work. I have learnt a lot from just a few messages and I appreciate the time and effort that went into the job." "I recently had the pleasure of working with Sascha to design my website, and I couldn't be happier with the results. From start to finish, Sascha demonstrated exceptional creativity, professionalism, and attention to detail. He truly listened to my ideas and brought my vision to life in a way that exceeded my expectations. The website is not only aesthetically pleasing but also user-friendly and responsive. I highly recommend Sascha for anyone looking for a website designer!" "Sascha applies himself to his work with great commitment and is always prepared to go the extra mile far beyond our expectations." "We have come to know Sascha as an absolutely trustworthy and reliable professional who possesses an extensive technical knowledge and has the ability to grasp new concepts quickly." "Sehr zufrieden, gute Arbeit und nette Kommunikation - gerne wieder!" "He is characterized by his target-oriented, enthusiastic and extremely flexible nature. Sascha proved a great deal of responsibility, takes decisive actions and proactively looks for solutions." "Great, he re-adjusted the order based on specific needs and was flexible. Enjoyed working with him and will do so again."

Many clients come to me as a Node.js Developer when a frontend already exists but API, data model, the business logic need to be done right. As a Backend Developer I keep the Node.js layer predictable, documented, as a Node.js Developer I handle API Integration third-party services, database, frontend. A typical Full Stack Developer React Node project for me looks like this: a SaaS platform or internal business tool with a React frontend, Node.js backend, structured database and an admin workflow for the team behind it. On every Full Stack Developer React Node build I design the database structure, the REST API , the dashboards, the permissions model so the product holds up as it grows. This Full Stack Developer React Node approach keeps frontend, backend in one system. Hiring one Full Stack Developer React Node engineer also keeps the React Developer and Node.js Developer decisions consistent across the whole build I also work as a Directus Developer | Headless CMS Developer . On 20+ content-driven, data-heavy products I use Directus CMS, Strapi as a headless backend, which gives clients a clean admin panel and an API-ready foundation. As Directus Developer I model the data, set roles and permissions, connect a React frontend through REST API ; as a Strapi Developer I do the same on Strapi. Headless CMS work with Directus CMS pairs naturally with my React developer firebase, Node.js Developer delivery Stack: React, React.js, Next.js, Node.js, TypeScript, JavaScript on the application side; ExpressJS, REST API , API Integration on the service side; SQL, MySQL, MongoDB, Firebase, Supabase for data; Directus CMS | Strapi for headless content.

Iโ€™m a software engineer with 20+ years of experience in low-level systems, reverse engineering, and performance optimization. I specialize in analyzing, decompiling, and reconstructing complex binaries across Windows, Linux, and embedded platforms. My focus is on understanding code others canโ€™t โ€” restoring logic, recovering algorithms, and making sense of obfuscated or legacy systems. Iโ€™m comfortable working with C/C++, .NET, and ARM codebases, using tools like IDA, Ghidra, ILSpy, and custom-built analyzers. I can help you with: - Binary or .NET decompilation and analysis - Control flow and data structure recovery - Anti-tamper and obfuscation removal for legitimate maintenance or migration - Code audits for security or compatibility - Low-level debugging and performance tracing
