A mid-level SQL Server developer with performance tuning experience plays a crucial role in optimizing database performance, ensuring data integrity, and developing efficient SQL queries. The candidate should be able to work independently on database-related tasks while also collaborating effectively with cross-functional teams to ensure the overall success of database-driven applications.
1.Database Design: Designing and implementing SQL Server databases, including creating tables, indexes, and constraints to meet application requirements efficiently.
2.SQL Query Development: Writing and optimizing SQL queries for data retrieval, modification, and reporting.
3.Performance Tuning: Identifying and resolving performance bottlenecks in SQL Server databases by analysing query execution plans, optimizing indexes, and fine-tuning database configurations.
4.Reporting: Creating and maintaining reports and dashboards using tools like PowerBI or alternatives.
5.Index Optimization: Creating, maintaining, and monitoring indexes to improve query performance.
6.Data Modelling: Designing and maintaining data models that adhere to best practices for normalization and denormalization.
7.Stored Procedures: Developing and optimizing stored procedures, triggers, and functions for data manipulation and business logic implementation.
8.Database Maintenance: Implementing backup and recovery strategies, as well as regular database maintenance tasks, to ensure data availability and reliability.
9.Security: Enforcing database security by configuring user permissions, roles, and authentication mechanisms.
10.Monitoring and Alerts: Setting up monitoring tools and alerts to proactively identify and address database issues.
11.Documentation: Maintaining documentation of database schemas, query optimisation techniques, and performance tuning efforts.

2.3-5 years of experience in a SQL development or maintenance role, preferably in a technology or finance-related industry.
3.SQL Proficiency: Strong knowledge of SQL, including complex query writing, subqueries, joins, and understanding of query execution plans.
4.Performance Tuning: Experience with SQL Server performance tuning, including query optimization, index management, and server configuration.
5.Database Design: Ability to design and implement efficient database structures, including normalization and denormalization principles.
6.Knowledge of reporting tools like Power BI or similar.
7.Query Optimization Tools: Familiarity with query optimization tools and techniques such as SQL Server Profiler and Database Engine Tuning Advisor.
8.Indexing: Knowledge of indexing strategies and the ability to create and maintain indexes for optimal query performance.
9.Stored Procedures: Proficiency in creating and optimising stored procedures, triggers, and functions.
10.Database Administration: Understanding of basic database administration tasks, including backup and recovery, security, and maintenance.
11.Monitoring Tools: Experience with SQL Server monitoring tools like SQL Server Management Studio (SSMS) and third-party monitoring solutions.
12.Version Control: Familiarity with version control systems (e.g., Git) for database changes.
13.Problem-Solving: Strong problem-solving skills to diagnose and resolve database performance issues.
14.Communication: Effective communication skills to collaborate with developers, DBAs, and other team members.
15.Continuous Learning: Willingness to stay updated with the latest SQL Server features and best practices in database development and performance tuning.
