Senior .NET engineer at Raklet, a multi-tenant SaaS platform that clubs, associations, universities and nonprofits use to run memberships, events, payments and communities. I joined in 2018 to build the test automation from scratch, moved into full-stack engineering, and today lead hands-on delivery across the core platform.
What I work on
- 💳 Payments & billing: Stripe & Stripe Connect, SEPA/ACH direct debit, PayPal, Iyzico; recurring billing, scheduled payments, coupons, refunds, saved cards, provider webhooks
- 🧩 Multi-tenant membership SaaS: plans and multi-currency pricing, applications, checkout, member portal, CRM/admin workflows, localization
- ⚙️ Background processing: continuous and scheduled Azure WebJobs, Service Bus and storage queues, Node.js Azure Functions
- 🔐 Auth & APIs: ASP.NET Identity, OAuth 2.0 bearer tokens, JWT, external login providers, REST APIs documented with Swagger/OpenAPI
- 🛡️ Reliability: idempotency, webhook replay safety, null-safety guards, async/await deadlock prevention, parameterized SQL, telemetry-driven debugging
- 🧪 Testing & delivery: a C# Selenium WebDriver framework built from scratch, MSTest/VSTest and Jest suites, Azure DevOps and GitHub Actions pipelines with automated browser tests gating releases
- 🤖 AI-assisted engineering: repository agent instructions, reusable skills and MCP integrations; agent workflows (Claude Code, Codex) that take work from triage to a reviewed PR, with CI gates and human review kept in the loop
