 
        
              With over 9 years of dynamic expertise in software development and
              tech leadership, I bring a proven track record of designing and
              implementing scalable APIs, socket services, and robust user
              interfaces using TypeScript, JavaScript, and PHP. My experience
              spans over 20 projects across diverse industries, including
              fintech, E-commerce, CRM, IoT, and more, showcasing my ability to
              quickly adapt to new technologies and collaborate effectively with
              cross-functional teams.
              
              I specialize in data model design, backend test automation, and
              CI/CD workflow orchestration, with a deep understanding of server
              administration on Windows, Ubuntu, and CentOS. Having launched
              projects on major cloud platforms such as Firebase, GCP, AWS, and
              Cloudflare, I am adept at managing MongoDB servers and integrating
              payment gateways like Stripe, PayPal, etc.
              
              In addition to my software development expertise, I am proficient
              in DevOps practices, leveraging tools such as Bash, GitHub
              Actions, Docker, Kubernetes, and VMWare. I have extensive
              experience with databases including MongoDB, PostgreSQL, MySQL,
              Redis, and Firebase, and I excel at building real-time single-page
              applications and mobile solutions using React, Flutter, and
              Electron.
              
              My technical acumen extends to various network protocols,
              including TCP, UDP, HTTP, WebSocket, and MQTT, along with
              expertise in both SQL and NoSQL databases. I’m also experienced
              with a wide range of tools and frameworks, including NestJS,
              Express, React, Angular, and more. Additionally, I have a strong
              background in Agile methodologies, including Scrum and Kanban, and
              am proficient in version control systems and cloud integration.
              
              With strong communication skills and the ability to lead complex
              projects from idea to profitability, I thrive in fast-paced
              environments where innovation and collaboration drive success.
