     Faster deployments

   Led the cloud migration to React/TypeScript and ASP.NET Core, provisioning AWS infrastructure from scratch with CDK and decomposing core APIs into resilient Fargate microservices. Now serving 23,000+ daily transactions and 1,000+ concurrent users with zero-downtime deploys.

   Cut deployment time 86% (90 → <12 min) by building end-to-end Azure DevOps pipelines covering automated testing, SQL migrations, and multi-environment AWS rollouts.

   Architected an event-driven communication layer across microservices using Amazon EventBridge and SQS, with idempotent .NET consumer workers guaranteeing once processing and fault tolerance during peak traffic.

   Ended recurring data divergence by co-engineering a REST sync layer that keeps an AWS RDS source of truth consistent with two on-premises SQL Server instances.

   Private Tutor, Computer Science Admission

   Preparing candidates for the Babeș-Bolyai Computer Science admission exam — algorithms, data structures and mathematical logic.

   Teaching the fundamentals under exam pressure — algorithm design, data structures and formal logic — to candidates preparing for one of Romania’s more competitive Computer Science admissions.

   Explaining is the sharpest debugging tool I own. Breaking a recursion or an invariant down until a seventeen-year-old can rebuild it from scratch is the same skill that makes an architecture decision defensible in a design review.
