Where speed meets strategy

I'm Joris, a full-stack engineer and product-minded founder helping startups, SMBs, and solo founders ship faster without hiring a full dev team.

With 7+ years of hands-on experience, I've bootstrapped products to €50k/month, built white-label SaaS for B2B, and supported founders go digital through web platforms, custom apps, branded websites, or simply the right advice. I bring deep technical execution, product sense, and business logic. All in one.

At JustOnline, there's no bloated team, no outsourcing, and no fluff. Just one engineer who thinks like three — backend, frontend, and product — dedicated to getting things done.

From streamlining operations to launching MVPs, I work directly with you to turn your vision into real, working software. Subscription-based. Flexible. Results-first.

Let's create something extraordinary, together.

FAQ

Frequently asked questions

Most requests are completed within 5 business days or less. Bigger features or complex builds might take longer, but I'll keep you updated along the way.
Once you subscribe, you'll be invited to your own Trello board within an hour. From there, you can start submitting requests right away. Simple instructions are included on the board.
JustOnline is a one-man dev team, me, Joris. No outsourcing, no middlemen. You'll work directly with me, start to finish.
Use Trello to share what you need. That can be a quick text brief, a Google Doc, wireframes, or even a Loom video. Whatever works best for you.
You can submit unlimited requests, and I'll work through them one at a time in a queue.
Larger builds are broken into smaller chunks and delivered continuously (every 24–48h). That way, you get progress fast and we stay aligned.
Absolutely not. I treat every project like it's my own. The goal is to deliver value fast, not to drag things out. You'll see steady progress every week, and I always aim to build trust through results, not time.
No problem. I revise until you're 100% happy. Collaboration is part of the process.
Absolutely. Use it for a month or a year, you're always welcome to return when you've got new product needs.
You're billed for 31-day periods. If you pause after, say, 21 days of usage, you'll still have 10 days saved for future use. Pause anytime, no stress.
That's fine! Use the time you need, then pause your subscription. Come back when you're ready for more. No waste.
Yes. If you cancel in the first week, you'll get 75% back. After that, or once work is completed, no refunds are offered.
I choose the best tools for your needs. Commonly MERN, Python/Flask, PostgreSQL, and modern front-end frameworks.
Yes. I don't take on projects in: banking, insurance, gambling, alcohol, fashion, beauty, or music industries. For values-alignment reasons.
Yes, but only if it's urgent. I prefer keeping all communication in Trello to stay organized and efficient. That's where I track everything. If something is blocking progress or time-sensitive, feel free to ping me directly on WhatsApp.
If something falls outside the core dev service, I'll let you know and help find the best path forward — we'll figure it out together.
