Julian Zieliński, Java Software Engineer
I design and build scalable systems and reliable software in Java.
I do not start by writing code for the sake of writing code. I start by asking what your business needs to achieve and what architectural demands the system must handle, and only then do I design and deliver stable Java solutions that make sense.
Approach
How I approach working together
Before I propose a solution, I want to know who it is meant to serve and which problem it actually solves. That is why the first conversation is about the business, not about website or system features.
I work directly: you talk to me, not to a project team that still has to learn your industry. If a project needs a bigger team, ONEXO joins in while the single point of contact stays the same.
What I do
Day-to-day work
- Designing websites and online stores
- Business consulting and idea validation
- Audits and growth work for existing companies
- Choosing tools, systems and automation
Career path
How I got here
- Start
First website projects
First builds for local companies, and the lesson that a good website starts with understanding the client, not with a template.
- Growth
Working with service companies and e-commerce
More and more projects that required thinking about the whole process: from the first visit to the completed purchase.
- Today
A personal brand and co-running ONEXO
I run projects myself, and for larger scopes I draw on ONEXO, the company I co-run, which covers branding and custom systems.

Larger projects
When a project needs a bigger team, I bring in ONEXO.
Some projects I deliver with my team at ONEXO, the company I co-run. That lets us handle larger builds covering the website, branding, marketing, ads, SEO, custom systems and automation, while you keep a single point of contact.

Got an idea and no idea where to start?
You do not need to arrive with a finished brief. Tell me what you want to do and we will work out together whether and how it is worth building.
