At Apiko, I've built backend systems for Syntho, Vidico, Jobheron, and Procon using C# and ASP.NET Core.
For Syntho, I implemented Stripe subscription billing with automated payments and webhook processing, and integrated AWS S3 and CloudFront for secure video storage and streaming.
For Vidico and Jobheron, I architected GraphQL and REST APIs, optimized PostgreSQL queries, and implemented secure authorization for file sharing and recruitment workflows.
I've also built reusable CSV and XLSX parsing libraries and automated import pipelines that replaced manual data-entry processes. I focus on clean architecture, API design, secure integrations, and performance optimization.
