What I'm looking for

I seek Senior Fullstack Developer roles building secure, high-concurrency SaaS platforms, .NET backends, Salesforce integrations, and modern web interfaces designed for global distributed environments.

I am a Senior Full-Stack Developer with 13+ years designing and delivering high-scale multitenant SaaS products for remote global clients. I focus on creating robust web services, secure identity flows, and dependable cloud-data integrations.

I specialize in bridging .NET with the Salesforce ecosystem using Apex, Managed Packages, SFDX CLI, and REST APIs, and I architect secure OIDC/JWT-based identity solutions. I have led integrations, migrations, and ETL efforts across SQL Server and Oracle environments.

My full-stack work spans backend APIs (.NET, C#, Web API), frontend interfaces (JavaScript, jQuery, SCSS/Foundation), and database optimization for high-concurrency workloads. I also incorporate AI-driven tools into the SDLC to accelerate delivery and improve capacity.

I hold a Bachelor in Computer Engineering with academic honors and bring proven experience in systems architecture, secure interoperability, and remote collaboration over more than a decade.
