Yesterday, my son Adam turned sixteen. Sixteen. It feels strange to write that number. In my mind, he is still the little boy who needed help with everything, who would run around the house with endless energy, ask a thousand questions, and somehow make even an ordinary day feel louder and more alive. But time […]
Around 2010, I spent most of my days working as a Java and C developer in the electronic payment industry. At that time, things were very different compared to today. There were no fancy AI coding assistants. No Stack Overflow answers for every problem.And debugging production issues sometimes meant sitting next to a physical EDC […]
Most people think people management is about: But after spending more than 10 years managing teams in technology, I realized something: Managing people is actually about managing energy, trust, pressure, communication, and expectations.

In payment security and cryptography, we often hear terms like key variant and key block. Both are related to how cryptographic keys are used and protected, but they are not the same thing. A simple way to understand it: Key variant is about modifying how a key is used. Key block is about securely packaging and protecting the key itself. […]
Product management is often seen as a role that focuses only on features, roadmap, and delivery timelines. But in reality, product management is much broader than that. It is about understanding problems, connecting business needs with technology, and making sure the solution being built actually creates value. From my experience in IT and Product Development, […]
Assalamualaikum warahmatullahi wabarakatuh, After four beautiful days in Makkah, our journey continued to Madinah, a city that feels different from the moment you arrive. Makkah was powerful, intense, and deeply emotional.Madinah felt calmer, softer, and peaceful. It is a city that teaches you to slow down, reflect, and feel gratitude in a quieter way. Day […]
When people tap a card on an EDC machine or complete a payment at a merchant, the process looks simple from the outside. A few seconds later, the transaction is either approved or declined.

The Google PQC migration timeline for 2029 is an important signal for the cybersecurity industry. In March 2026, Google made it clear that post-quantum cryptography preparation is no longer a distant plan, but an immediate strategic priority.
