WebGuysFull-stack development, light and lean.
I build fast, lightweight, and reliable web applications — from SaaS platforms to educational systems — working solo but with full team-level responsibility.
A developer, not an agency. And that's the advantage.
Hey! I'm Maciej (Magic, or Theran) — a full-stack developer running WebGuys as a one-person brand. I work remotely, currently from the Costa del Sol in Andalusia, for clients in Poland and abroad.
I don't sell "enterprise solutions". I build concrete, working products — no WordPress, no unnecessary dependencies, no abstraction layers that slow down both the code and communication with the client. One person who understands the whole stack from database to UX means fewer misunderstandings and faster rollouts.
For a few years I've also been using AI agents (OpenCode, Claude, Grok, ChatGPT, DeepSeek, Gemini and others — depending on the need) in implementation — but as a senior architect and reviewer, not a prompt operator. That lets me deliver more while keeping the code quality I'd sign with my own name.
What I do
A pragmatic stack without forced trends.
Full-Stack Development
PHP, Next.js, MySQL — frontend and backend built by one person means coherent architecture from day one.
SaaS & Product Development
From idea to working product: architecture, payments (PayU, Stripe), multilingual support, gamification, admin panel.
AI-Assisted Development
Modern AI tools in everyday work — faster delivery, the same architectural control, full code review of every line.
Entrepreneurship
I build not only for clients but also my own products — from white-label LMS to e-commerce platforms. I understand the business behind the code.
Who I help
Startups
An MVP before your runway runs out.
Online education
A course platform with no monthly subscription.
Real estate
Multilingual listings without manual translation.
Creators & personal brands
A website and newsletter you fully control.
What does it cost
An exact quote always comes after a short conversation — here are rough ranges so you know which direction to look.
Brochure site
from 1500 PLN
A simple site with the essentials (Home, Services, Contact) — for businesses that need a professional online presence without advanced features.
Website with CMS / blog
5000–15000 PLN
For businesses that want to update content themselves, run a blog, or have a more extensive offering.
Online store / SaaS / web app
15000–25000+ PLN
For projects with payments, user login, external integrations, or custom business logic.
Featured projects
Case studies and deliveries — from idea to production.
How I work
A proven process that delivers projects.
Discovery call
We start with what you actually need — not a feature list everyone has. Realistic quote, no hidden costs.
Architecture before code
I design the data structure and API before writing a single frontend line — saves weeks when changes come mid-project.
Iterative rollouts
Regular demos, not "you'll see it ready in 3 months". Production releases step by step, with full testing of migrations and permissions.
Support after launch
Code I understand from the ground up means fast responses to bugs and changes — no waiting for someone to recall how it works.
Why WebGuys
Lightweight, not bloated
No WordPress or unnecessary frameworks. Effect: your site loads instantly and doesn't slow down as you add new features.
One person, full responsibility
You don't go through sales, design, and development departments. Effect: one person knows the full context from start to finish — fewer misunderstandings, faster decisions.
Modern stack with real experience
PHP, Next.js, AI-assisted development. Effect: solutions tailored to your actual problem, not to whatever is currently trendy.
Pragmatism over trends
I pick tools for the project, not the other way around. Effect: you don't pay for features you don't need, or to maintain tech that exceeds your business scale.
What clients say
“Maciej built EspanaSol for me from scratch — a fast, multilingual property presentation platform that just works. The website loads instantly, looks professional in four languages, and I no longer have to manually translate any listing — the AI pipeline does it for me. The collaboration was quick and stress-free, he knew exactly what I needed.”
Katarzyna Tomczak
EspanaSol“I met Maciek in what you'd call an 'emergency.' My computer crashed — for a YouTuber recording regularly at the time, that was close to a disaster. Back then (the second decade of this century), we each edited our own videos, and the computer was more important than the fridge. 'Come over,' he said — so I got in the car and drove 150 km for the 'repair.' That same evening, I was back to work and edited my new video. That's how our friendship began. Regardless of the many hours of fascinating conversations we've had over the years — about life and death, wisdom and ego, consciousness and lucid dreaming — computers and how we use them remained the leitmotif of our increasingly warm bond. Maciek helped me set up a discussion forum, helped launch my subsequent blogs, migrated my mailboxes from server to server, helped with hosting, and has been — and still is — my constant IT support for many years. He was my WordPress teacher, and continues to be my advisor on communication platforms and new messaging apps. And by the way — he's a wonderful partner for conversations about how similar a computer is to our mind. Because it is... I wholeheartedly recommend working with Maciek. First and foremost in the realm of computers and the internet. Although not only :)”
