I am a hardworking, proactive Full-Stack Developer with over 10 years of professional software development experience, proficient in both .NET and Java technology stacks. I specialize in building stable, scalable, and enterprise-level web applications and business systems. On the .NET side, I am skilled in C#, ASP.NET, .NET Framework / .NET Core, Web API, JavaScript, MSSQL, MySQL, and Oracle databases. On the Java side, I am experienced in Spring Boot, Spring Cloud, backend service development, RESTful API design, and enterprise system architecture development. I have independently developed and participated in multiple large-scale commercial projects, including OA systems, workflow management systems, government administrative approval systems, and ERP enterprise resource management systems. I am capable of requirement analysis, full-cycle development, database design, system debugging, deployment, and performance optimization. Additionally, I am highly proficient in AI-assisted development. I am experienced in writing high-quality AI prompts, utilizing various AI tools to accelerate coding, optimize logic, troubleshoot technical issues, and improve overall development efficiency and code quality. I can quickly understand technical requirements and deliver standardized, stable, and maintainable project outputs. I have 4 hours of stable available working time every day and can provide long-term, consistent, and high-quality development support for ongoing projects.

I help regulated businesses and high-growth technology teams build secure, scalable cloud systems and bring infrastructure costs back in line with actual usage. Cloud architecture across AWS, Azure, and GCP is one half of the practice. The other half is enterprise systems integration: Microsoft Dynamics 365, Salesforce, SAP, and Oracle, including a SAP architecture for a European heavy industrial manufacturer under strict defense-sector compliance, and a full legacy-to-current Oracle migration carried out with training and complete data integrity. Dynamics 365 in particular runs on Azure and Dataverse, so the enterprise systems work and the cloud architecture work are not two separate practices. They inform each other directly, the platform a business runs on and the infrastructure underneath it. Built for production load, not demo load, audit-ready for SOC 2, ISO 27001, and GDPR standards. What I deliver for your business: Cloud Architecture and Migration: planning and migrating existing workloads to high-availability multi-cloud environments. Enterprise Systems Integration: architecting and integrating Dynamics 365, Salesforce, SAP, and Oracle, spanning regulated industrial, manufacturing, and enterprise sectors. Infrastructure as Code: designing clean, modular Terraform configurations for policy-based resource provisioning. Container Orchestration: deploying and managing Kubernetes platform infrastructure, observability, and release pipelines. DevSecOps Hardening: implementing access controls, firewall constraints, and securing CI/CD pipelines through GitHub Actions, GitLab, and Jenkins. Cost Optimization: conducting cloud billing audits, setting up budget alerts, and removing resource waste. Available for project-based work or ongoing infrastructure and systems support. Send over what you are building or what is not working, and you will get a direct technical read back, including an honest answer on whether I am the right fit for it.
