What I do

What I can do for you

Focused on three things that actually move the needle for your business.

⚡

Custom Development

Hand-coded HTML/CSS/JS, PHP/MySQL — no WordPress, no page builders. You get exactly what you need, nothing you don't.

📈

Speed Optimization

I fix slow sites. 90+ PageSpeed scores, core web vitals, and hosting that doesn't suck. Results in days, not weeks.

🔧

Maintenance & Support

Security updates, backups, and small tweaks on demand. Flat monthly rate, no surprise invoices, no contracts.

Who I am

I'm Chesea Dev.

Full-stack developer since 2024. I don't do page builders, I write clean, fast code that loads instantly and ranks on Google. I've built for startups, e‑commerce brands, and agencies.

My work is 100% custom, 100% mine, and built to last. When you work with me, you're not getting a template — you're getting a site engineered for performance from line 1.
