Is your application slowing down due to sluggish database performance? Don't let unoptimized queries ruin your user experience. Let's fix it.


I am a Software Engineer specializing in relational databases. I will analyze, refactor, and tune your PostgreSQL database to achieve lightning-fast response times and robust data integrity.


What I Can Do For You:

- Query Optimization: Rewriting slow queries, fixing complex JOINs, LATERAL subqueries, and JSONB handling.

- Index Tuning: Applying proper indexing strategies to eliminate full table scans.

- Schema Design: Designing normalized, scalable table structures and relationships.

- EF Core Optimization: Fixing inefficient LINQ queries and array unnesting issues.

- Stored Procedures & Triggers: Building or debugging database-level automation and integrity.


Why Choose Me?

- In-depth knowledge of PostgreSQL internals and transactional integrity.

- Production-safe optimizations that protect your data.

- Clear explanations of the bottleneck and the solution.


Every database is unique. Please send me a message with your current setup and logs before placing an order so we can plan the best fix!
