The short version

How I got this fast.

Then

15+ years of shipping products, not just sites

I started with WordPress sites for small businesses. For the last 7+ years I've been a full-stack developer on the Xagio team, the SEO & AEO platform behind a WordPress plugin with 10,000+ active installs, where a team of about a dozen people covers everything from DevOps to design. Along the way I also worked on Keyword Supremacy, SerpScout and Viral Supremacy, and built the unglamorous software that keeps real companies running: Balextra inventory and wholesale, the TailoredPitch CRM, the Vabis product catalog.

Now

AI agents do the grunt work. I do the senior part.

I don't paste into ChatGPT. I run agent workflows that scaffold, test and refactor overnight, then I review every line the way I'd review a junior's pull request. The repetitive 80% went from days to hours. The 20% that decides whether it actually works (architecture, edge cases, taste) is still me.

So

Which is why the prices look wrong

When a landing page takes an afternoon instead of a week, I don't need to charge a week. Flat prices, fixed dates, 30 days of free adjustments. If agencies could work this way, they would. Most of them have a payroll that says no.

How I work

Six rules I don't break.

  1. 01

    A number, not a feeling.

    Every job ends with a measurement: speed score, ranking, conversion, uptime. If I can't measure it, I tell you before we start.

  2. 02

    Fixed price, fixed date.

    You get one page: what, when, how much. If I misjudged the work, that's my problem, not your invoice.

  3. 03

    Reply within hours.

    8:00 to 23:00 Belgrade time, I answer. Not an auto-responder, not a ticket number. Me.

  4. 04

    Boring technology, on purpose.

    WordPress, PHP, Node, Postgres, Astro. Things that will still run in five years and that the next developer can read.

  5. 05

    No plugin soup.

    If three lines of code do the job, I won't install a 40-plugin stack and call it a build. Fewer moving parts, fewer 3 a.m. emails.

  6. 06

    You own everything.

    Code, accounts, domain, hosting. Full access from day one. I'd rather earn next month's work than lock you in.

Stack

Tools I reach for every week.

Picked for longevity and speed, not for the logo wall. If your project needs something else, I'll say so.

What I've actually shipped.

  1. SEO platforms

    Xagio (team), Keyword Supremacy, SerpScout, Viral Supremacy

    7+ years as a full-stack developer on the Xagio team. The ecosystem: a WordPress plugin with 10,000+ active installs, the Cloud App, the Agent X and Studio AI site builders, hosting, AI-traffic analytics and a marketplace, 1,150+ sites hosted. I also worked on Keyword Supremacy, SerpScout and Viral Supremacy for keyword research, SERP monitoring and referral links.

  2. Business apps

    Balextra, TailoredPitch, Vabis

    Inventory, wholesale and sales for a retail business; a CRM with orders, invoices, tickets and a client portal; a product catalog platform. The kind of software a company runs on every single day.

  3. Client sites & my own sites

    Shops, service businesses and lead-gen sites

    Client work: the Bob's Leathercraft store, the Vabis catalog, a photographer's site in Ljubljana, a junk-removal site in Miami. My own lead-gen sites in Philadelphia, Portland and Akron and my own wedding-photography site in Slovenia rank on Google's first or second page for their money keywords.

  4. Today

    TailoredFix

    One senior developer with AI agents on a leash, selling fixed-price builds and monthly subscriptions to businesses that want things done this week, not this quarter.
