• As a valuable member of a small team, I developed and maintained an internal C++ event-based framework. I typically started with a loosely defined idea based on client requests, which our colleagues across the company clarified through customer communication. Occasionally, I coordinated with other departments when new features depended on their work. I then designed the required features for our framework, implemented them, and provided comprehensive documentation and training materials. My main goal was to deliver a simple, easy-to-use, and safe API, with clear implementation and high test coverage.
• I also volunteered to create and regularly deliver presentations to our customers about new features and how to use them properly. Additionally, I participated in promoting our framework to potential clients to attract new customers.
• Beyond new feature development, my role involved support. I investigated numerous bugs reported by our clients and examined their code when they encountered problems with our framework. This allowed me to quickly dive into code and troubleshoot issues based on logs and core dumps.

• As a C++ developer at Waves Audio, I collaborated with my colleagues on a cross-platform product for the audio industry. During this time, I gained experience in maintaining products for both Windows and Mac, which were used by famous musicians worldwide. I also successfully ported the C++ plugins infrastructure from Windows and Mac to Linux, working alongside a junior developer whom I guided and mentored. This task involved creating CMake configurations, writing new unit tests with gtest, implementing system-specific functions for Linux using Gtk, and creating and maintaining Jenkins jobs for different artifacts.
• Another significant achievement was optimizing the OpenGL ES engine used to render the user interface on embedded devices. I utilized tools like perf and Intel Graphics Performance Analyzers to identify and eliminate bottlenecks. By applying modern techniques to reduce the number of OpenGL calls and offload more computations to the GPU, I was able to double the performance.

• As a C++ developer, I have solved nontrivial bugs in complex distributed system environments involving multiple communication protocols such as TCP, UDP, SCTP, SIP, and SIGTRAN. These systems provided telecommunications operators with intelligent network services, handling call-related logic such as blacklisting, whitelisting, redirection, and more.
• One of the most memorable bugs I encountered was in a live system and led to a memory leak. It couldn't be reproduced in the testing environment, so I had to start with a 4 GB core dump and an overly complex C library for IP-telephony protocol parsing. With the help of GDB and a hex editor, I was able to identify the root cause of the problem and resolve it, even though my manager was prepared to pay penalties.
• When needed, I quickly ramped up on Spring framework programming and assisted my colleagues in completing a project on time.
• I also patched the Golang project Stolon to meet our project's requirements for data replication, significantly reducing downtime in our PostgreSQL cluster when the master node was lost.

• As a software developer, I designed and implemented utilities to automate the routine tasks of my colleagues, the radio engineers, based on their requirements. I led discussions and gathered feedback directly from the engineers.
• I successfully delivered a Qt-based application that collected the health status of Ericsson RBS 6000 and RBS 3000 series before and after software installation, helping engineers effectively identify problematic stations from a list of hundreds.
• Another major achievement was a web application that tracked the current software versions for thousands of Ericsson RBS 6000 and RBS 3000 base stations, detecting those that had been sporadically downgraded. This significantly reduced the time needed by the software upgrade team to identify such stations and perform timely upgrades.
• Additionally, I was involved in the initial setup of Ericsson RBS 6000 and RBS 3000 series (including parameters, transport, and other configurations). A mobatch script I created based on that experience helped the engineering team accelerate their work by 40%.
