I've been developing applications in such areas as industry - Manufacturing Execution Systems, Warehouse Management Systems, banking Systems and applications for public administration. Extensive experience in databases and programming allowed me to smoothly switch to my current role as Data engineer. In most of the projects, I participated in the design of the application logic, data model and implementation. I believe that learning and good understanding of business processes is crucial to a successful design. Knowledge of general programming concepts - OOP, databases, procedural programing allows me to quickly learn and adapt to new various technologies. Also working as as system administrator in the past extended my overall IT experience and it is still very useful when communicating with other IT specialists. In my professional career I have been working with multiple different programming languages: Python, SQL, PL/SQL, T-SQL, Java, Delphi, C and even very rare programming languages like 4GL- Panther/jam or Clipper. Due to long experience I’m capable to understand and work with either legacy technologies as well as state of the art solutions like AWS. Regardless of technology the goal is always to deliver application/solution with clean, straightforward design and readable code that can be easily modified and extended by others. I'm rather a back-end minded developer, however in many projects I have implemented also client UI - mainly desktop applications. I’m very positive person with can-do attitude.Tech Stack
