I build scalable, high-performance backend systems with .NET Core and modern microservices — from clean API design through CI/CD and production operations. With 7+ years of experience, I help startups and growing businesses design maintainable APIs and backends that handle real-world traffic reliably. I’ve worked as both a hands-on developer and technical lead. My expertise includes: • ASP.NET Core & Web API • Microservices & RESTful API design • SQL Server, MongoDB, Redis • Auth (OAuth2, OpenID Connect, JWT) • Docker & CI/CD (Azure DevOps, GitHub Actions, Jenkins, Octopus Deploy) • Cloud (AWS, Azure, Google Cloud) • Legacy modernization & system integrations • LLM-backed features (OpenAI / Ollama) when the product needs them I’ve delivered complex backends, integrated third-party APIs, modernized legacy platforms, and supported production systems on cloud infrastructure. If you need: ✔ A solid backend for a SaaS or startup ✔ Clean, maintainable API architecture ✔ Performance, caching, and reliability ✔ Legacy system modernization ✔ Scalable microservices with real CI/CD and cloud deployment Happy to discuss your project.
