Thank you. If you need someone who understands the entire stack - from the metal to the cloud - we’ll be a good fit. Let’s talk. I am a server-side focused engineer who spent over 6 years honing my craft in C# even before my office career began. And I'm don't just write code; I build systems that work across Windows, Linux, and Android. Whether it’s a program communicating directly with hardware via USB or a high-traffic server processing complex data, I deliver clean, stable, and maintainable results. My work is rooted in 𝗧𝗲𝘀𝘁-𝗗𝗿𝗶𝘃𝗲𝗻 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 (𝗧𝗗𝗗). I believe in building it right the first time so it doesn't break later. Beyond writing code, I have a track record of setting up the infrastructure that runs it - from creating custom Docker images to orchestrating Kubernetes clusters and mentoring the next generation of engineers. 𝗪𝗵𝗮𝘁 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵: • 𝗟𝗮𝗻𝗴𝘂𝗮𝗴𝗲𝘀: C#, Java (native for android, Spring Boot), PHP (Laravel, Symfony), JavaScript (Vanilla, jQuery) • 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱: Angular (with adaptive/responsive layout expertise) • 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 & 𝗗𝗲𝘃𝗢𝗽𝘀: Kubernetes, Docker (Custom Image Creation), CI/CD Pipelines • 𝗗𝗮𝘁𝗮 & 𝗠𝗲𝘀𝘀𝗮𝗴𝗶𝗻𝗴: Kafka (Message Brokers), Elasticsearch (Full-text Search) • 𝗦𝗽𝗲𝗰𝗶𝗮𝗹𝗶𝘇𝗲𝗱 𝗦𝘆𝘀𝘁𝗲𝗺𝘀: WinAPI, USB-port communication, Security System Development • 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀: Windows, Linux, Android I’ve worked both in tight-knit teams and as a solo developer. I expect every project to have its own unique challenges - whether it's a legacy monolith or a greenfield cloud-native app. I’m 𝗿𝗲𝗮𝗱𝘆 𝘁𝗼 𝗮𝗱𝗮𝗽𝘁 my stack to your specific needs.
