The Problem
What Happens When You Hire an Agency
Dev Roulette
Your project gets passed between junior devs. Each one re-learns your codebase — adding time and inconsistency.
Hidden Tech Debt
Quick fixes and shortcuts pile up. The site works "for now" but breaks when you try to grow or change things later.
Slow Timelines
Layers of project managers and handoffs mean your 4-week project becomes a 3-month saga.
The Difference
One Senior Dev. Start to Finish.
One Developer, Zero Handoffs
I personally handle every line of code. No juniors, no "team leads" who vanish after the sales call.
Built Right the First Time
Clean architecture, no shortcuts. Your site works today and scales tomorrow without expensive rewrites.

What Clients Say
Real reviews from Upwork and Trustpilot
“Hired Adrian on a tight deadline and he handled it like a pro. I gave him a punch list and he knocked it out item by item, acknowledging each task and communicating every delivery along the way. That kind of transparency is rare and honestly made the whole process stress-free. He covered everything, WordPress, Elementor, custom code, bug fixes, and the work came out clean and polished. Knows his stuff, doesn't overcomplicate things, and you never have to chase him down for updates. Would 100% work with him again.”
“Adrian KICK-ASS. Very competent and hard worker”
“Always reliable, professional and great communication skills.”
“Adrian is highly recommended as he works hard and delivers. His credo quality above speed, was one of the most important factors for hiring him. I would hire him again. (and he is a really nice guy!)”
“Adrian has been very accommodating. When hiccups came up Adrian took the trouble to look into it and settled them. I would recommend him for your jobs.”
“He is the best.”
