What I do - and what I don't.
Core competencies and honest boundaries.
🚀 What I do best
- Complex database logic, PL/SQL, and data-heavy backend systems
- Commissions management, reporting, and internal data workflows
- Oracle Cloud infrastructure and APEX applications
- Custom internal tools built around how your business actually works
✅ What I can also help with
- Personal websites and smaller internet business cards - clean one-pagers that present you or your business professionally
❌ What I prefer not to take on
- Large public-facing marketing websites
- SEO, analytics, and conversion campaigns
- E-commerce platforms where design and sales performance are the core product
I'm not a native web developer - and I won't take on work where I'm not confident I can deliver real value for your money. If your project falls into this category, I'll tell you upfront and point you in a better direction.
Zero infrastructure cost. Just bring your idea.
For small businesses put off by the price of developers and infrastructure.
You don't need a €500/month cloud bill to have a real, working application. Using Oracle Cloud's always-free tier, I can take your idea from zero to production - with a custom domain being your only recurring cost.
Database
Production-grade Oracle DB
Application
APEX or a modern stack
OCI
Oracle Cloud — always-free tier
Mailing
Transactional email
IAM
Identity & access management
You own everything. The infrastructure is in your name, under your control. No vendor lock-in - if you ever want to move or bring in another developer, nothing is holding you back.
Personally, I think this approach is ideal for proof of concepts, smaller applications, or anything that doesn't expect massive traffic. It's the easiest way to get everything - database, application, email - in one place, without paying a dime. For many small businesses, it stays the right choice long after launch.

Key projects I've worked on
O2 Czech Republic
- Hard to access Informatica logs and schedules — built a custom app to manage Informatica with logs, dependencies and scheduled runs
- Old data piling up with no cleanup — built a data-aging app for automatic archiving and gradual deletion
- Data checks were scattered across the system — built a generic framework for data validation
- Data model changes deployed manually with no checks — set up a CI/CD pipeline using Liquibase, SQLcl and TypeScript
