I am a proficient mathematician and gained my PhD degree in mathematics in 2008. My field of research is mainly partial differential equations analysis but also includes ordinary differential equations and numerical modelling. I have published a number of high-level research papers, worked as a referee for scientific journals and wrote reviews for Mathematical reviews. I can help you with understanding research papers in this field, writing mathematics-related texts and reviews, and research tasks. I have teaching experience with university courses on partial differential equations, numerical analysis and calculus. Also I can help students with courses on algebra, geometry and ordinary differential equations. I use Octave for numerical modeling and teaching. I worked as a web developer in the past (mainly back-end, PHP and SQL) and can write code for mathematics to include it in the main program. I am also familiar with Python and C on a basic level.

Are you looking for a professional software developer who can solve unsolved tasks, is highly organized, and has deep knowledge and experience developing optimized and robust code? I'm an experienced and dedicated professional with over 16 years of experience in designing, developing, implementing, and supporting software solutions. My aim is to create fast, lightweight, and highly optimized solutions that perform well with minimal use of system resources. My favorite kind of work is solving unsolvable problems. My main skills are fast learning and ongoing professional development. Last two years I made mostly cross-platform desktop/mobile applications on the Qt framework using C++, QML, and CMake. Difficult unsolvable problems are my favorite job. And I am sure that my experience, knowledge, and enthusiasm will help to solve any of your problems.

Music Notation & Engraving | MuseScore | Choral & Orchestral Scores | Sacred Music I'm an academic composer and professional music engraver with 8+ years of experience delivering publication-quality notation for soloists, chamber ensembles, choirs, and orchestras. What clients hire me for: Music Notation & Engraving (MuseScore 4) I produce clean, performance-ready scores from scratch or from your existing materials. Whether it's a solo piece, a string quartet, or a full symphonic work, the result is a print-ready file that meets publisher standards. Choral & Sacred Music Editing I specialize in liturgical choral settings — hymns, antiphons, and ancient church melodies harmonized for SATB and other vocal configurations. I handle prosody carefully, ensuring every syllable falls naturally on the correct beat and stress. Orchestration & Original Composition From academic chamber works (including unconventional ensembles like Trio + Organ) to full orchestral arrangements — I write and orchestrate in styles ranging from tonal to contemporary. Transcription from Audio/Video I transcribe music by ear from recordings with high accuracy and format it into clean, editable scores. Live recordings, studio tracks, or archival audio — all handled professionally. Non-Standard & Contemporary Notation Experienced with music without barlines, proportional notation, graphic scores, and other non-traditional formats. If you need a choral score edited for an upcoming performance, an orchestral transcription completed on deadline, or an original sacred anthem composed for a specific liturgical occasion — I deliver precise, detail-oriented work with deep respect for musical tradition. Message me with your project details and I'll respond promptly. Keywords: music notation, music engraving, MuseScore, choral score, orchestral arrangement, sacred music, liturgical music, SATB, music transcription, sheet music, score editing, music composition, hymn harmonization, choral music editing, orchestration, chamber music, string quartet arrangement, music copyist, academic composition, contemporary notation, church music, vocal score

C++ / Qt engineer, 20+ years. I build the software that runs machines and instruments: embedded Linux firmware, Qt/QML operator HMIs, and the cross-platform desktop workbench engineers use to configure, calibrate and log. RECENT WORK - HPLC syringe pump - control software for an analytical laboratory instrument. - Firmware, control suite and workbench for the Multistage cable-stripping machine. - ScanScore / Forte / Bandora - 8 years on cross-platform music-notation software in Qt: optical score recognition, MIDI, PDF export. - Debian POS server - multithreaded C++ service, PostgreSQL, ESC/POS thermal printing, deployed onsite. 18,000 hours on Upwork at 100% Job Success, Top Rated Plus. WHAT YOU GET I lead a small Lviv team - firmware, HMI and desktop under one contract - and I stay hands-on in C++/Qt myself. You talk to me, not to an account manager. - Embedded & HMI: STM32, Arduino, embedded Linux, Qt/QML touch panels, industrial operator screens. - Desktop: cross-platform Qt for Linux and Windows; C#/.NET (WPF, WinForms, DevExpress) when the Windows side needs it. - Data: PostgreSQL, MS SQL, multithreaded C++ services, reporting, printing, installers. HOW I RUN PROJECTS - YOU SEE EVERYTHING Offshore teams fail on visibility, not on code. The process is built to remove that risk: - Private Jira server - you get an account and watch the board in real time. - Every code change is linked to its Jira task. Nothing lands untracked. - Code lives on our BitBucket Git server; you get access. - Every reported developer hour carries the developer's own comment explaining it. - Weekly and monthly reports, generated - not improvised. - A working demo build every week. You judge progress by running it, not by reading a status update. Scope is agreed as Work / Time / Budget with defined milestones before anything starts. Background: SoftServe 2002-2008, developer to tech lead; then my own team since 2014. ALSO AVAILABLE: legacy Windows rescue - MFC, Win32, COM/ATL, Visual C++ 6.0, WinForms/.NET. The desktop applications other developers won't touch. I have been maintaining and modernizing them since 2002. Send me the machine, the instrument or the old application - I will tell you honestly whether we are the right fit.

Hi, my name is Arsen. I’m a Senior C++ and Python developer with 5+ years of experience building software for Linux, Windows, and embedded systems. I focus on clean, efficient, and reliable solutions for low level, backend, and performance critical tasks. What I bring to projects: • C/C++ development: STL, Boost, Boost ASIO, Qt, WinAPI, OCCI, V8, POSIX, multithreading • Python development: automation tools, data pipelines, backend logic, Django • Database engineering: Oracle, SQLite, MongoDB, data export tools, batch processing, custom type conversion • Linux systems programming: networking utilities, driver level interaction, Linux kernel headers, OpenWRT, desktop and CLI tools • Wireless and low level networking: Generic Netlink, nl80211, libnl/libmnl, Wi Fi scanning tools, protocol and frame parsing • Reliability and performance: profiling, transactional workflows, data integrity focused design, Dockerized builds, CI/CD with TeamCity • Cross platform delivery: Linux and Windows applications, Make, CMake, Conan, Git/SVN, GDB, Valgrind, Doxygen, Bash I have built tools ranging from high performance Wi Fi scanners in C that interact directly with the Linux wireless stack, to cross platform C++ command line utilities that export Oracle data into SQLite with transactional safety and performance profiling. I am comfortable working close to the system, optimizing throughput, handling large datasets, and designing software that is maintainable and stable in production. Clients usually trust me with complex backend, systems, and infrastructure related tasks where performance, correctness, and long term reliability matter. If you are looking for a developer who can work on C++, Python, Linux internals, networking, or data heavy applications, let’s talk. 🙂
