Hire the Best Debuggers
in Ukraine

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. 🙂

If your system got slower over time and nobody really knows why — that’s usually where I come in. Most developers avoid messy data, slow queries, and systems nobody wants to touch. That’s where I do my best work. My core is .NET and SQL. Not just writing queries, but understanding why things break when data grows, and fixing it without turning everything upside down. What I work with: • C# / .NET — data processing, automation, background services, desktop tools • SQL (deep) — complex queries, performance tuning, execution plans, large datasets • APIs & backend — REST, Node.js, Linux deployments • Automation — Selenium, scraping, data pipelines, legacy integrations • Infrastructure — Docker, Linux, FastAPI, PostgREST, full stack setup • Frontend — AG Grid, WordPress customization I also use AI in real work — tools like Claude and AI agents help me move faster, understand unfamiliar stacks, and scale solutions without slowing down. So if your project runs on something new — that’s not a blocker. I’ve worked with old and undocumented systems too — where you don’t have docs, only behavior. If you already tried the obvious fixes and they didn’t work — that’s usually when I get involved. I don’t need long explanations. I read the system, find the real issue, and fix that. I won’t promise miracles. But I will tell you exactly what’s wrong and what it takes to fix it.

I am a seasoned software developer with over 10 years of experience specializing in Backend and Full-Stack development. I pride myself on my excellent problem-solving skills and have a strong passion for writing clean and testable code. Clear communication is one of my strengths, making me a valuable team member in any software development project. Preferred Tech Stack: Backend: Java, Spring Boot, Thymeleaf, REST API, PostgreSQL, AWS, Linux, Tomcat, Nginx Frontend (Web): HTML, CSS, Sass, Javascript Frontend (Mobile): Flutter, Dart Cross-Platform: Flutter, Dart I am also proficient in the following technologies: Languages: Java, Scala, Groovy, Kotlin, Golang, JavaScript, TypeScript, Python, Dart, SQL Databases: PostgreSQL, MySQL, Oracle, Cassandra, MongoDB, SQLite, Neo4j Frameworks (Backend): Spring Boot, Spring Security, OpenAPI, Kafka, Zookeeper, Grails Frameworks (Frontend): Angular, React, Flutter, jQuery, Bootstrap Security: Spring Security, OAuth, JWT Technologies: HTML, CSS, JSON, XML, REST API API: REST API, OpenAPI, Swagger Messaging: Kafka, ActiveMQ, RabbitMQ Search: ElasticSearch, Lucene, Kibana Logging: ElasticSearch, Logstash, Kibana Cloud Providers: AWS, Google Cloud Testing: JUnit, Mockito, TestNG, Selenium, Cucumber, Katalon Studio Development Tools: Intellij IDEA, VSCode, Android Studio

My current specialization is the powerful PHP frameworks - CodeIgniter (14+ years exp.) and Laravel (2+ year exp.). I am also heavy experienced in the following areas: HTML, CSS, MySQL, Maria DB, JavaScript, TypeScript, Ajax, JQuery, Bootstrap, Tailwind, Git etc. My past projects were related to full stack or backend developing - creating new website pages, creating and maintaining API, enhancing or boosting SQL queries, bugs fixing, integrating 3rd party plugins/services/APIs (AWS, payment gateways etc.) and so on. I like to learn something new and I don't afraid to use any software that I haven't used before. That's why I already successfully finished many projects with different difficulty levels. So I'll be glad to use my developing experience to please you with great results. Hope for our cooperation.
