You will get Fix Website Speed, Core Web Vitals & Mobile Issues — 48Hr Delivery
Project details
Your website is slow, failing Core Web Vitals, or broken on mobile. I will fix it.
I specialize in front-end performance optimization for custom HTML, CSS, and JavaScript websites. Slow load times, poor PageSpeed scores, and broken mobile layouts are directly costing you visitors and revenue. I identify exactly what is causing the problem and fix it cleanly.
What I fix:
— Page load speed and render time
— Core Web Vitals (LCP, CLS, FID)
— Mobile layout and responsiveness
— Image optimization and lazy loading
— CSS and JavaScript bloat
— Render-blocking resource issues
— Cross-browser display inconsistencies
— Navigation and interaction problems
— Basic on-page SEO structure
My process starts with a full Lighthouse and PageSpeed audit. I prioritize by impact, fix the highest-value problems first, and deliver a documented report of everything changed.
You get a faster, cleaner site with a before/after score comparison.
Delivery within 48 hours. I work on custom HTML, CSS, and JavaScript sites only — not WordPress.

Hello, I’m Emmanuel (you can call me Michael) a Software & Automation Engineer with a strong foundation in computer science and hands-on experience building scalable automation systems, AI-powered workflows, and full-stack web solutions.
Over the years, I’ve worked extensively with JavaScript, Python, Node.js, Express, and modern web technologies, but my real specialization lies in automation engineering using tools like n8n, APIs, webhooks, and system integrations. I design workflows that connect platforms, eliminate manual work, and keep businesses running intelligently in the background.
I don’t just build interfaces, I build systems:
AI-driven automations
Custom workflow logic
Email, CRM, and data pipelines
Website and app automations
Backend logic with full control and no platform limitations
I’ve built everything from authentication systems (signup, login, email confirmation) to real-time chat flows, automated outreach systems, and AI-assisted processes that help businesses respond faster, scale smarter, and stay ahead of their users.
What sets me apart is how I think:
I focus on reliability, logic flow, and long-term scalability, not quick hacks. Every system I build is designed to be editable, extendable, and production-ready.
I enjoy working with founders, startups, and companies that want more than “just automation” they want solutions that actually work.
If you’re looking for someone who can turn complex ideas into clean, intelligent systems, you’re in the right place.
Let’s build something that matters.
