I’m Stepan, a .NET software engineer focused on e-commerce automation and Shopify apps. For the last 4+ years I’ve built production-grade integrations, background jobs, and admin tools that cut manual work, reduce errors, and surface real-time metrics.

What I do
• Shopify apps (embedded UI with Polaris/App Bridge), Admin & Storefront REST/GraphQL, webhooks
• Product & order automation (bulk listings, data cleanup/mapping, supplier-ready exports)
• Data pipelines & dashboards (Facebook CAPI/offline conversions, ROAS/CPA tracking)
• API integrations (ERPs/CRMs, payment/shipping, custom services)
• AI-assisted features (embeddings/semantic search, smart classification)
• Secure, scalable backends (auth, rate-limiting, background jobs, caching)

Tech I use
C#, .NET 8, ASP.NET Core, EF Core, PostgreSQL (incl. pgvector), Redis, Docker, Kubernetes, React/Next.js, Tailwind, ONNX/OpenAI, Hangfire/Quartz, GitHub Actions.
