Built "SoundTrek" in early 2024, when Replit AI was still finding its footing. It mapped your favorite sounds and found similar artists, a fun little experiment powered by last.fm Crazy to think how quickly these tools have come since then, you can build production-ready apps at lightning speed. ⚡

In this web design project, I explored the possibilities and different approaches to scrolling animation, fine-tuning the timing and flow of transitions to different scenes, and engaging users in website interactions through simulating game mechanics, all while working in a style uncharacteristic of my own. https://80s.studio-template.com/ The web design was completed in Wix Studio using the Velo API. I love and am proud of this work—the website was showcased on the Wix Studio Inspiration Page. https://www.wix.com/studio/inspiration/site/the-museum-of-adventures

https://www.horizont.net/ is a digital media platform focused on industry news and analysis, designed for high editorial throughput and frequent updates. The system is built around a robust server-side architecture with a structured content model, optimized for performance, SEO, and scalability. The frontend follows a classic web approach, enhanced with JavaScript-driven components for dynamic content, user interaction, and responsive layouts, rather than relying on a full single-page application

Firewood Delivery Logic & Maps Integration ➤ The Challenge: A local firewood supplier needed to automate delivery quotes. Manual distance checking was slow and prone to errors. ➤ The Solution: I built a custom Vanilla JS tool with deep Maps API integration: • Google Maps API: Automated real-time distance calculation for every order. • Dynamic Pricing: Logic that factors in wood type, volume, weight, and mileage. • UX/UI: Lightweight, mobile-first interface for instant customer quotes. ➤ The Result: • Automation: Zero manual checks needed; instant pricing for customers. • Efficiency: Eliminated pricing disputes and optimized the booking flow. • Performance: High-speed tool with zero external library dependencies.

Industrial B2B Growth & Maintenance Value ➤ The Challenge: A legacy industrial site was invisible to engineers. Goal: Transform it into a lead-gen tool via technical excellence. ➤ The Solution: I deployed a comprehensive technical and content strategy: • Custom JS Engineering: Developed an intricate lifespan calculator for parts. • 100/100 Speed: Reached perfect performance scores via deep code refactoring. • Expert Content: Launched a research-driven blog that dominated technical search intent. ➤ The Result (The Evidence): • Growth Spike: Deployment led to a 400% surge in organic traffic. • The Maintenance Gap: As shown in the chart, the cessation of expert support ("Too Expensive") coincided with a clear loss of momentum. • Proven ROI: Technical excellence isn't just a setup - it's the engine that sustains market leadership.

Achieving 99/100 Mobile Speed & Breaking the Traffic Plateau ➤ The Challenge: The site was stuck in the "Yellow Zone" (~70 PageSpeed). High-quality content was held back by technical overhead, resulting in a stagnant traffic plateau. ➤ The Solution: I executed a deep technical overhaul to unlock the site's ranking potential: • 0ms Blocking Time: Eliminated JS execution delays for instant interactivity. • Visual Stability: Achieved a 0.001 CLS, ensuring a perfect UX. • Speed: Optimized the rendering path to hit 0.9s FCP and 99/100 Mobile score. ➤ The Result: • Plateau Broken: Technical fixes (last green dot on chart) acted as a catalyst for new organic growth. • Elite Performance: Sustained 99+ PageSpeed scores on mobile. • Business Impact: Improved rankings and higher conversion rates.

100% Organic Growth via Technical Refactoring The Challenge: Stagnant traffic and poor mobile UX due to bloated legacy scripts (jQuery), unoptimized media, and weak semantic structure. The Solution: I executed a deep technical overhaul to modernize the stack: • Vanilla JS Migration: Replaced jQuery with pure, high-performance JavaScript. • Smart Media: Implemented WebP/AVIF, responsive sizes, and lazy-loading. • SEO Foundation: Cleaned HTML semantics and added Schema.org microdata. • On-Page: Refreshed Meta Tags to align with search intent. • Bootstrap 5 Tuning: Optimized CDN delivery and CSS path for zero speed impact. The Result: 99–100 Mobile PageSpeed: Perfect scores even with a CSS framework. Traffic Surge: Organic growth from 14K to 30K+ monthly sessions in 12 months.
