You're missing a voice for your project? Hi, I am a voice actor from Bremen/Germany. • Warm, bassy voice for audiobooks, voice-overs, image films, explanatory videos, commercials... • Own studio • High-quality setting • Remote recording via Teams, Skype, Zoom. I'm looking forward to our next project, let's get started! Best, Jonas

I sit at the intersection of precise front-end engineering, high-fidelity design, and cutting-edge AI orchestration. If you are an early-stage founder, a fast-moving startup, or a professional service brand, you don’t just need a web developer—you need an independent solution architect who can take a blueprint and ship a launch-ready MVP in weeks, not months. By combining advanced Prompt Engineering, Replit sandboxing, and Vibe Coding workflows, I bypass traditional development bottlenecks. I operate a full-scale digital development lab independently, ensuring that your web application is built cleanly, fully responsive, and performance-optimized at extreme speed. 🛠️ The Technical Stack I Command: Platforms: Webflow (Certified Professional), Premium WordPress Architecture AI & Prototyping Stack: Replit, Advanced System Prompting, Agentic Developer Frameworks Front-End & Interactions: Semantic HTML5/CSS3, responsive frameworks, interactive UI transitions, and clean bento-box layouts. Integrations & Data Flows: Custom forms, advanced analytics tracking, automated email capture, and background workflow automation (Zapier, custom hooks). 🎯 What I Deliver: End-to-End Execution with Minimal Supervision: I handle everything from hosting configuration and domain routing to basic SEO setup and responsive QA independently. Absolute Discretion: Highly comfortable working on stealth-mode, early-stage, and founder-led initiatives under strict NDA requirements. Clean, Scalable Codebases: Whether launching native code inside Replit or clean structures in Webflow, your site will be lightweight, easily manageable, and built to convert traffic into trust. Stop wasting time with generic template installers or slow development agencies. Let’s collaborate to leverage modern AI acceleration and bring your technical vision to reality. Click the "Invite to Job" button to hop on a screening call and discuss your project scope. 🚀 Key Improvements Made: The First Paragraph is a Hook: It explicitly targets founders and startups, making them realize you understand business outcomes, not just code. Highlighted the AI Advantage: By explicitly putting Prompt Engineering, Replit, and Vibe Coding right at the top, you immediately match clients looking for fast-to-market execution who want to capitalize on modern AI-driven development. Kept the Focus Monolithic: Notice there is zero mention of digital assets, print layout, or unrelated services. This strict technical separation keeps your profile's internal Upwork score perfectly locked into the high-paying Web Development category. Clear Call to Action (CTA): The final sentence literally tells the client what action to take next, which heavily increases conversions on profile views.

I specialize in building high-performance, robust web scrapers using Golang. If you need clean, structured data from complex websites, I can help you automate the collection process, save your time, and ensure data accuracy. My expertise includes: Golang Expertise: I use the power of Go to create fast, concurrent scrapers that handle large-scale data tasks efficiently. Advanced Scraping: Experience in bypassing anti-bot protections, managing residential proxies, handling dynamic content (JavaScript-rendered pages), and managing session persistence. Data Delivery: I provide data in the format you need (CSV, JSON, Excel, or direct integration into databases/Google Sheets). Reliability: I focus on building resilient scripts that monitor themselves and handle errors gracefully, ensuring you don't lose data due to site structure changes. Whether you are looking to extract real estate listings, e-commerce product data, or need to automate a repetitive data entry task, I deliver scalable and maintainable solutions.
