  • Connection and Session Management: Proficiency in Entity Framework Core, strategies for efficient connection pooling, handling, and session management.
  • Load Balancing and Multi-Tenant Optimization: Experience with best practices in multi-tenant applications, including horizontal scaling and load distribution techniques to optimize databases for high-demand usage patterns.
  • SQL Optimization: Skilled in using database profiling and query optimization tools like SQL Profiler and Extended Events. Knowledge of advanced query rewrite techniques, indexing strategies, and performance tuning for highly efficient SQL databases.
  • Problem Solving and Analytical Skills: Strong problem-solving skills and an analytical mindset to systematically identify and address performance issues.

What We Offer:


  • Impactful Work: Directly influence the performance and cost-efficiency of our SaaS platform, ensuring our systems remain blazing fast and cost-effective.
