I am a backend-focused full-stack developer specializing in C#, ASP.NET Core, and scalable RESTful API development. I build maintainable web applications with an emphasis on clean architecture, SOLID principles, and practical software engineering practices.
I have professional experience developing multi-tenant CRM, LMS, and POS SaaS platforms. My work includes end-to-end backend ownership, lead ingestion, business automation, subscription and payment features, database optimization, and cloud-based media workflows.
I work with ASP.NET Core, ABP Framework, Entity Framework Core, PostgreSQL, React, Angular, and TypeScript. I am comfortable applying Domain-Driven Design, CQRS, repository patterns, dependency injection, and modular monolith architecture.
I have implemented authentication and authorization solutions using OAuth2, OpenIddict, JWT, SSO, and RBAC. I also have experience with Azure Blob Storage, Cloudflare Stream, AWS services, Docker, GitHub Actions, and Azure DevOps.
I enjoy solving performance and scalability challenges, including query optimization, caching, pagination, full-text search, and direct-to-cloud uploads. I am seeking a full-stack developer role in the .NET ecosystem where I can contribute strong backend expertise while continuing to grow my React and Angular skills.
I work remotely as a core developer on two multi-tenant platforms: a CRM and a learning management system. I own and deliver backend modules end to end using ASP.NET Core, ABP Framework, React, and PostgreSQL.
My work includes lead ingestion from landing pages and Meta webhooks, rule-based scoring, round-robin assignment, WhatsApp messaging, and automated workflows. I also develop LMS media pipelines with direct Azure uploads and Cloudflare Stream integration.
I contributed part-time to a multi-tenant POS SaaS product built with ASP.NET Core, ABP Framework, Angular, and PostgreSQL.
I worked on payment gateway integration, subscription plans, query optimization, database-level pagination, and filtering. These improvements reduced query execution time from approximately 15 seconds to under 300 milliseconds in relevant scenarios.
I completed a remote full-stack development internship focused on industrial software development practices using ASP.NET Core, Angular, and PostgreSQL.
I contributed to the user interface of a POS SaaS application and built an open-source SSO ecosystem authentication server with an administrative panel.
