At Havas Edge, I develop and maintain C# (.NET 8) WinForms applications that automate internal business processes and reduce manual effort across production workflows. I also troubleshoot production issues and improve existing modules using SOLID principles and design patterns.

At Locobuzz, I developed and maintained ASP.NET Core APIs for Salesforce CRM integration, supporting applications handling over 50,000 requests per day. I optimized SQL Server queries, stored procedures, and indexes, and worked on JWT and OAuth 2.0 authentication.

My project work includes a Salesforce CRM integration platform with real-time bi-directional sync and observability, plus a multi-vendor e-commerce application and a financial management SaaS platform. I work with C#, .NET, SQL Server, and Azure, and have experience contributing within Agile development teams.
