Firt, let me explain how is that possible to have so many titles, have a very wide and deep knowledge in all of the roles, so I can be a IT "jolly-joker" professional.

The short answer is: beeing lucy, hardworking & passionate, visionary, thinking out of the box.

The more detailed answer is:
Beeing lucy to start to learn development when the IT sector born, and grow up with it. In early days the developer had to have all of the knowledge as there were just few IT persons, so beeing alone lead to be an enterpreuner and develop multiple skills all at high level, like very good planing and task management, prioritise and quick decision make, but also flexible and agile.

Beeing a hardworking & passionate: knowing unique things which helps others is part of my personality and is a main driven feeling which leads to passion, and when you learn & work with passion your knowledge and experience can't be stoped by the problems and issues, they became challenge and resolving them is an award for me.

Beeing visionary: Because there was no principles, standards defined individual roles, I has to create my own to keep organized and meet deadlines. Therefore I became a "Lazy IT professional" who didn't had the time and willing to do repetitive tasks. Being alone in all these roles resulted in time deffieciency. Thie has led me to deelevop and gain further skills. So I develeoped the planing and task management skills to a very high standard, as I realized a good planing save a lot of time in the future and reduce the stress. I had to learn the hard way to develop quickly but flexible (AGILE + SCRUM), bugfree - TDD driven development - (less Helpdesk support) and close to 0 maintenance (everything has to be automatized and monitored and logged - system/app/data backups and HA high availability).

Thinking out of the box : In many case, where issues arise, after a while you need to stop fixing the issues, lay back and start to think from different aspect. For example: I wrote a complex and good aplication which became victim of its success, started to have so many clients, and data that the server resource started to be not enough. Step 1: Code & data optimization is the first step, but there is level when you can't gain the necessary speed. That's when u need to stop, lay back and think about other steps. Step 2: fine tuning the system, database, applying caching method and mechanism. Step 3: updating the server resource, adding more memory, faster HDD, adding a new server,etc... Step 4: changing application flow. Separating the inputs and queries, putting the long queries/reports to be executed in background, and anounce the requester when it's done. Step 5: Changing the Application mechanism: Adding loadbalance, CDN, static serving, switching from serverside processing to client side process, optimize bandwith data transfer

How is that really possible to have really so wide experience and knowledge?

Started in early 90's with DOS on a XT 2MHz 640kb(0.65 Mb) RAM, 20MB MFM HDD IT just became my hobby. Code optimization, speed & data optimization at that time was a must, when the users had no idea what a PC means user friendly app was a must. Businesses not knowing what a PC/IT is, how the IT could improve their business. Because of that I had to be: a Sales manager, IT Project Manager, Customer realtionship manager / Business Analyst / CIO&CTO / IT & System engineering Manager & Asset Manager / Hardware technician/ Software administrator / Network Engineer & Network Administrator / DR (disaster recovery) specialaist storage & backups / Security officer (data security, later network security) / IT suppert / Application developer, Databaase administrator, later Web Developer / Help Desk Support At the begining I was doing all the roles alone, but I was not able to keep up with the technology grow, so I started to put more energy in learning and less in gathering new clients. I started with a 5 year learnig getting a professional advanced degree as developer.
