01 / What I build
Practical solutions.
Where the work happens.
Your processes are unique. Your tools should fit the way your business actually works.
Software built for your people.
Purpose-built applications for support functions, back-office teams and manufacturing operators. Clear interfaces with solid engineering underneath.
Make your data useful.
Advanced Excel solutions and Power BI reporting that bring clarity to complex data. From preparing the numbers to making them actionable.
Different environments. Same pragmatism.
Comfortable with
complexity.
Grounded in reality.

I'm Xavier, the freelance engineer behind LOGINX DATA SRL, based in Romania. I bridge business operations and software engineering, with strong Python, front-end and back-end skills, and deep expertise in Excel and Power BI.
I use agentic development to extend what one person can deliver. AI-assisted implementation supports the work; architecture, review and delivery remain my responsibility. You work directly with the person building your solution.

What should
work better?
A repetitive task. A spreadsheet that has outgrown itself. A process that needs its own tool.
