About this Gig
Slow queries, timeouts or a messy database design can hold back your whole application. I help businesses design, fix and optimize SQL Server databases and the Entity Framework Core code that uses them.
With 14+ years building data-driven .NET applications, I focus on practical fixes you can measure.
What I can do:
- Analyze slow queries and execution plans
- Add or fix indexes
- Rewrite stored procedures, views and functions
- Fix inefficient Entity Framework Core queries (N+1, tracking, over-fetching)
- Design normalized schemas with ER diagrams
- Write complex T-SQL reports and queries
- Also MySQL and SQLite on request
What you get:
- Optimized scripts or code changes
- Before/after timings where measurable
- A short report explaining what changed and why
Please message me before ordering with your database type, approximate size and the problem you see, so I can confirm the right package. I never need your production passwords in chat; we can agree on a safe way to access a copy of the data.
FAQ
Which databases do you work with?
Mainly Microsoft SQL Server. I also work with MySQL, SQLite and MongoDB. Tell me your database and version before ordering.
How do I share my database safely?
Ideally share a backup or a copy with test or anonymized data, or a script of the schema. If live access is needed, create a separate limited account; never send production passwords in chat.
Can you fix Entity Framework Core performance?
Yes. I review the generated SQL and fix common issues such as N+1 queries, missing indexes, unnecessary tracking and loading too much data.
Will I receive the full source code?
Yes. You receive all scripts and code changes made for your order, plus a short report explaining what changed and why.
Is my data kept confidential?
Yes. Your database, code and business details are used only for your project and are never shared with anyone else.
What if my project is bigger than Premium?
Message me with the details. Larger work is best handled with a custom offer split into milestones, so you pay and review in stages.
