Frontend developer who ships.

Solo dev. Direct contact. No agency overhead. For founders and small teams who want things done.

Weeks, not months

Most launches in 4-8 weeks. Phases for the rest.

Built for production

TypeScript, tests, and code your team can extend later.

Predictable delivery

Clear scope, honest timelines, on-time launch

For app & SaaS founders

What are you building?

Product UIs that make users come back. Built with React, Next.js. Shipped on schedule.

What I deliver

Products users come back to

  • Next.js frontends shipped on schedule
  • Dashboards users understand at a glance
  • Onboarding flows that activate users
  • Accessibility-ready interfaces from day one
  • Design systems your team can build on

The friction

Where growth stalls

  • Onboarding flow that loses users on signup
  • Users churn before finding their aha moment
  • Every new feature takes twice as long to ship
  • Designs that never match the live product

The outcome

What ships differently

  • Onboarding that delivers value in minutes
  • Product that looks like the company behind it
  • Architecture that scales with your roadmap
  • Code your next dev can extend without me
Let's build your app

I usually reply within 24h. No commitment.

FAQ

Frequently asked

Answers to the most common questions about working together.

  • Most projects fall between $8k–$20k. Smaller themes and fixes start around $3–5k. Headless builds go $18–25k. I always send a fixed quote, no hourly billing, no surprises.
  • Depends on scope. To give you a sense:

    1. Landing page or simple website: 1–2 weeks
    2. Shopify Plus build/migration: 3–8 weeks
    3. SaaS MVP: 4–8 weeks
    4. Full custom rebuild: 8–12 weeks, shipped in phases

    Bigger projects always go in phases. You see working code every week, not a black box for 3 months.

  • I always show you the result after every week. If something is going off track, you'll know after week 1, not after 3 months. If you're genuinely not happy with the direction, we stop. You only pay for completed work.
  • The best way to find out is to just reach out. Use the contact form below and I'll get back to you within 24h. If I'm fully booked, I'll tell you upfront and point you to someone I'd trust with my own projects.
  • Three reasons:

    1. Direct contact: you talk to the person writing the code, not a project manager.
    2. Faster shipping: I don't have agency overhead, so 80% of agency work happens in 50% of the time.
    3. Better economics: agencies bill 2–3× what I do for the same output.

    The tradeoff: I'm one person, so I can't take on a 10-engineer enterprise project. For everything else, same quality, lower price, faster.

  • That's actually fine. I work better with a rough idea than a 40-pagespec. We'll spend the first 30 minutes scoping it together, for free, and you'll leave with a clear plan whether we work together or not.
  • If you're in the US, UK, or EU: yes. ADA lawsuits hit small businesses every week, and the EU Accessibility Act became enforceable in June 2025. I build all sites WCAG 2.1 AA compliant from day one, not as a $5k add-on later. For existing sites, I offer audits that flag what needs fixing before someone files a complaint.
  • I keep communication simple and efficient:

    1. Async-first: Email, Slack, Loom
    2. Weekly Loom updates instead of recurring calls
    3. Clear proposals, async decisions
    4. Direct communication - no middle layers

    This works best for founders and teams who value focus and trust specialists to execute.

    If you prefer frequent meetings and structured, agency-style check-ins, we might not be the best fit. If you want to move fast with minimal overhead - let's talk.

  • Three steps:

    1. Send me a message via the form above with what you're building, timeline, and budget.
    2. I'll reply within 24h with either a quote or a quick call to scope it.
    3. We sign, kick off, and you see first working code within the week.
Testimonials

Client stories

I highly recommend Mr. Marcin Szabłowski for personal branding websites. We had a great brainstorming session where I could explain my idea and Mr. Marcin advised on technology for my website.

Soon after aligning the details I had the results delivered with the highest quality. Everything works perfectly and I got all what I needed to progress with my business. Thank you!

We wholeheartedly recommend working with Marcin. We had the pleasure of completing three projects together and we keep coming back. We have been working long-term, so we know we can count on him in any situation - he always finds solutions to technical problems quickly and effectively.

I wish every collaboration were at this level - if someone wants something done well, efficiently, and without hassle, this is definitely the right address.

I have been working with Marcin for years. Thanks to him I have a new, beautiful blog. He migrated me from an unintuitive, template-based WordPress to a brand new website he wrote specifically for me, tailored to my vision and needs. Marcin is a specialist who pays attention to detail and never overlooks even the smallest things.

On the new website he also built a shop with a complete payment module, so I can sell my product independently without paying commission to anyone. I highly recommend Marcin for anything related to your website.

We worked together on an online store project. Marcin delivered the project in under 3 weeks. I was kept up to date on progress, which gave me full control over what was happening.

The collaboration went smoothly and I am very satisfied with the final result. Highly recommended!

I worked with Marcin on a new sports website project.

Very good communication, everything explained logically, clear scope of cooperation. I hope it was not the last project together.

He is a wonderful person whom I would love to work with again in the future.
