hi! I am Lefos
I build fast websites and run campaigns that convert.
Web developer and performance marketer in Athens. One person, both tracks: the site, the campaigns that fill it, and the analytics that prove it.
Trusted by real clients across both tracks
Current favorite tools, both tracks
What working with me looks like
Fast and optimized
Performance is a feature, not a finish line. I build static-first sites with performance budgets, and this site holds itself to the same standard.
Data-driven
Every decision traces back to a number: raw spend, raw revenue, real conversions. Ratios get computed from totals, never averaged from averages.
Full-funnel
From account architecture to creative testing to the landing page itself. When one person owns the whole funnel, nothing gets lost in handoff.
How I work
Static first, measured always
Sites ship pre-rendered with performance budgets, and every campaign ships with tracking that was planned before the first euro of spend. If it cannot be measured, it does not ship.
AI as a multiplier, not a replacement
Claude and ChatGPT are in my daily loop for code, analysis, and drafts; Midjourney for creative exploration. They multiply the hours, but the judgment about what to build and what to spend stays human. Mine, specifically.
Evidence over tools
No single SEO tool gets the final word: I cross-reference Search Console, Semrush, Ahrefs, Screaming Frog, Lighthouse, and the rankings themselves before recommending anything.
Featured work
Four builds and one campaign story. Full lists live on their own pages.
