    20+ years as a developer using various technologies and programming languages, combined with knowledge of all major databases. My vast experience include (but not limited): a- embedded C for automotive industry b- C++/C#/Pascal/Delphi/Lazarus for Windows/Linux/Android/iOS/MacOS both desktop and mobile. c- PHP/Java/JavaScript/HTML for various web projects d- Databases include (but not limited): Access/Interbase/Firebird/MySQL/Oracle/MSSQL/PostgreSQL e- Office advanced knowledge (VBA) for Access/Excel (macros/scripts/forms) f- Raspberry Pi - General programming / Embedded for IoT g- Electronics and Hardware/Software integration (experience with various readers/sensors included). Also I like to design my own PCB's for various pet projects I use around my house - I use Altium (former Protel) and OrCAD for this. h- Cryptography - secure communication / protocol analysis i- AI on both speech and visual recognition. Neural network training for OCR was one of my first love 20 years ago and continued on this field ever since. Ask me any advice, programming related of course, I'll give it to you for your project for free, even if you don't hire me. I've seen way too many clients here on Upwork getting scammed with false promises only to get scammed out of their money but more importantly getting their time wasted for months. My motto: "If I will win the lottery and become multimillionaire I will still do programming, at least for my personal satisfaction". Programming is my hobby, along with electronics and chess. We're a team, husband and wife, she's the designer and I am the programmer. Account is made on her name due to official documents being easier to send/receive since we live in her house. That's it, no other reason - this last section was provided more as a clarification for Upwork staff then clients.

    I am coding more than 23 years now. Mostly with Delphi and databases (MS SQL, Firebird/Interbase) and on huge (from hundreds of thousands to millions of lines of code) projects, and usually it is supporting. That's why I love to write apps from scratch as well :). The second language I use extensively is C++. Besides of coding, other my valuable skill is (reverse-)engineering software architecture. I love unit testing, as well as automating other software development aspects, i.e. automated builds etc. Also have some knowledge of Java, JavaScript, HTML, Basic, Unix scripting.

At a Glance: Delphi

Introduced by Borland in 1995, Delphi is an integrated development environment (IDE) for the Object Pascal and C++ programming languages. If you wish to rapidly generate native code for Windows, Mac OS X, iOS, or Android, an expert Delphi developer can help you get your software project started.

Delphi developers on Upwork can quickly build stand-alone executables, GUI applications, and other software on a wide range of platforms. While Delphi is not as well known as similar languages, including C++ and C#, the IDE still has a market for modifying GUIs for legacy systems, generating standard DLLs, ActiveX DLLs, and native Windows widgets. A fast compiler, large visual component library, COM compatible interface, and the ability to quickly build apps with cross-compatibility on iOS, OS X, and Android have triggered a resurgence in popularity for the IDE. Experienced Delphi developers can take advantage of Rapid Application Development (RAD) principles to quickly build and deploy applications on a wide range of desktop and mobile platforms.
