Open Internet Proxy
Proxy server for mobile operators which is fully modular and is capable to handle various traffic, especially protocols like HTTP, RTSP, XMPP and many others.
It is capable to do many things from basic content modification through video optimization to almost anything due to its own scripting language which allow to create many customer based modifications.
Me and Radek Bartman came with idea of using OIP for charging customers for using "smart" messaging such a Facebook messenger, WhatsApp and other IMs. We came with proof of concept and won a second place in competition with more than 20 other ideas on "Prague Innovation Cup 2011". Our idea was also presented at GSMA Mobile World Congress 2012.

New Integration Platform
New Integration Platform (NIP) integrates other systems (old and new ones) which use different interfaces (such as web services, databases). Reason for replacing old piece of software is fact that company CETIN splits off from O2 Czech Republic and thus need independent systems, not only for legal reasons.
NIP consists of several application servers, one of them is exposed to internet for communication within other ISPs. Other ISPs can order infrastructure rental, send orders, create tickets, check for service availability on specific address and much more.

Project Selfcare
New integrated client portal built on greenfield.
The portal allows customers to order, configure and manage their assets (vehicles, toll units, fuel cards, etc.), view and download invoices, filter and export transactions and many more in modern and user-friendly fashion, that all on all kinds of devices, from mobile phone to PC. Intuitively, responsively and without issues.

Project Cash Loans
Project aimed on mortgages and cash loans, composite from several applications.
I was responsible for part called "Elbos", it has front-end and back-end, but in production only backend is used.
Elbos is responsible for crediting (sending requests to payment system) a loan to customer and debit payments from their account according to schedule of repayment. It is also responsible for coordination of guaranteed in case of mortgages.
It is brain of solution, it takes outputs from risk, customer database, internet banking and it gives output to IB, payment system and accounting.
