I am a product focused R&D engineer. Last years attention has been on software development, and I have now 9+ years of experience on developing Android apps. I have worked on many published apps, and some of them have a large user base. I have learned a comprehensive knowledge of Android framework and how to build Android apps from bottom to top, and manage their publishing in Google Play. Android app development has happened in a close collaboration with product owner, backend team, design/UX people and QA. I have some experience of backend development and developing tooling app's to PC's too. In earlier years of my career, I have gained also much R&D experience from software development to embedded systems, electronics & hardware design, and hardware prototype building & testing, especially with medical devices.Programming skills:- Android: kotlin, java, MVVM, DI, jetpack frameworks, in-app camera, maps, positioning, device sensors, automated testing, obfuscation, REST/MQTT backend connectivity etc.- Developing for android & iOS with Flutter framework- Software architecture design- C, some assembler and low level programming, HW interfacing in microcontroller environments- Other languages: Python, JavaScript, QT, C++- Other frameworks & technologies been in touch: node.js, MySQL, PostgreSQL, REST, cloud APIs, Jenkins, vagrant- git, github- Scrum/agile methodologiesElectronics design skills:- Embedded control systems- High voltage power electronics (SCRs, IGBTs)- Mains part of an equipment, electrical safety- Sensor interfacing (e.g. temperature, biosignals)- MEMS gyroscope & accelerometer, magnetometer - EMC, 60601-1-2- Medical devices, 60601-1- PCB schematic and layout design- FPGA- Microcontrollers
