    Hello, my name is Andrii. In my childhood, I spent a lot of time with a soldering iron, making different interesting things. At high school, I got a PC at home and started... Dos, Win, Linux, FreeBSD. At the present time, I have more than 20 years of Win experience and more than 16 years of *nix experience. I like to build systems and solve interesting issues. OS - FreeBSD, Linux (CentOS, Alma, Rocky, RHEL, Ubuntu, Debian, Gentoo, etc), Windows (3.1-2019) Virtualization - vSphere 5.x, 6.x. Standalone ESXi and clusters with SAN storages (iSCSI).

    I have formidable Linux (RHCA, RHCSE) and Java (SCJP) experience, but I am more interested in Python and Android recently and I gathered some knowledge in many distinct areas (Novell, Oracle, MySQL, PHP, Cisco, etc.). I'm a general IT specialist - non-trivial / multidisciplinar problems gravitate to me, as I like to tinker and dissect problems. Having a bit of OCD (even though I prefer the term "perfectionist") I also enjoy menial tasks like cleaning up databases, commenting code or creating user training manuals. I am looking for side jobs, projects.

On a daily basis, I usually deal with providing consulting services, managing whole networks, Cloud Engineering on AWS / GCP and Azure platforms as well as handling lots of dedicated servers for various professional needs. What I usually do are listed below - Installing / Upgrading your system and scripts This is what I usually deal with on a daily basis. - Setting up your servers, RAID, ESXi, Proxmox etc. I personally run a dedicated server/mail / antispam business. - OS and Application level Linux Administration. / DevOPS I currently have clients that I look after. I usually keep their systems up-to-date, roll new releases of their software on the system, configure their servers, monitor their servers and whatever else they need. - Network Administration Although it is not my strong suit, I personally run my own ASN using Bird and Mikrotik announcing my own IPs through anycast BGP for my own use as well as client machines and VMs. - Mail Administration As I provide Mail services AND Anti-Spam Gateways, I do know a bit about what gets delivered, what gets stuck and I can try my best to work it for your needs as well. - DNS Server Administration I run various Bind and PowerDNS nodes for Geo DNS purposes. This includes Reverse DNS servers as well as your regular domain.com servers. - Monitoring Systems Zabbix / Smoking and such are the usual tools that I frequently use to run my businesses smoothly. - Plesk / cPanel / LAMP / DirectAdmin Are some panels I use for business, used or installed.

I am willing to learn new stuff and work towards a common goal as long as we can communicate our needs and requirements from the start and thank you btw for reading these lines as most usually tend to skim the text and move to the next person. I can tell you here that even if you didn't see what you are looking for, chances are that I already know about it. Just try asking me or inviting first. As I already have a company of my own, some of my time is already sold out. We can discuss it in detail when you tell me what exactly you want to do, what do you expect me to do and such. I strongly believe that we can find a way to do what you need to be done.

    ABOUT ME I have 20 years of embedded software and firmware experience. I am versatile and always eager to learn something new. I have worked on all phases of embedded software development. Ranging from board bring up to bare metal, RTOS, and embedded Linux systems. Over the years, I've also picked several graphics frameworks and mobile development. I will always guide my clients to the best solution for their use case. All the development work will be done by me, no outsourcing. HARDWARE • Work closely with hardware engineers, read schematics and able to understand the full system of an embedded project. • Assist with board bring up and handle low level components like DDR configuration and calibration. • SoC interfaces like I2C, SPI, UART, USB, I2S, as well as hardware peripherals like GPS, ADCs, LCD (LVDS), LTE Modem, BLE, WiFi. • Comfortable using oscilloscopes, DVM and logic analyzers. PLATFORMS • Worked on several processors with limited resources that were either bare metal, Arduino or have some kind of RTOS (FreeRTOS, TI-RTOS). Low level driver code, application code, and system level design (FW Update and config). • Experienced with Embedded Linux projects. Drivers, kernel config, bootloader (u-boot) modification, system level design and config. • System services/applications written in C/C++, IPC and network sockets/API. • Complex Linux build systems including Yocto, buildroot, AOSP (Android Open Source Project), Pi-Gen (Raspberry Pi OS builder) and custom Debian OS deployments. • The goal of creating a good platform is to develop processes that are repeatable and other team members can leverage and build on top of. APPLICATIONS • Once the low-level embedded code is in place, I will usually get involved with the application and GUI frameworks that run on the embedded system. • Develop GUIs to test the low-level hardware. • Provide reference implementations to guide app developers on how to interface to hardware. • Settings/Configuration UI for production systems. • Examples of UI work: PyQt GUI or web app running on an embedded Linux device. A Java Android app running on the custom hardware that runs Android OS. A mobile app (iOS Swift) to receive BLE (Bluetooth) data from an embedded device. Electron based desktop app to communicate with REST API or hardware device. LANGUAGES C/C++, Python, Java, JavasSript, HTML/CSS, Swift, Bash/Shell scripts.
