You will get I will fix optimize and debug your PHP backend applications
Project details
You will get a deep SQL performance optimization service focused on reducing query latency, improving database efficiency, and ensuring scalable system behavior under load.
With extensive experience in backend systems, complex SQL analysis, and performance tuning (MySQL/MariaDB), I specialize in identifying bottlenecks in execution plans, JOIN strategies, indexing, and data access patterns.
Each optimization is based on real execution profiling (EXPLAIN, query tracing, temporary table analysis) and results in measurable improvements such as reduced response time, lower DB load, and improved concurrency handling.
This is not just query rewriting — it is full system-level performance analysis aimed at making your database production-ready and scalable.

About Kirill
Engineering Owner | Backend Systems (PHP / Fintech / APIs)
Podgorica, Montenegro - 3:31 pm local time
I architect and build scalable PHP (Symfony/Laravel) systems including payment workflows, integrations, and high-load MySQL databases.
I have led backend design decisions in production systems, improving database performance by up to 8x through query optimization and architectural redesign.
My focus is system reliability, scalability, and real-world production delivery — not prototypes.
Steps for completing your project
After purchasing the project, send requirements so Kirill can start the project.
Delivery time starts when Kirill receives requirements from you.
Kirill works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements & Data Collection
Client provides available information about the issue, such as slow SQL queries, table structures, expected vs actual behavior, or a general description of the problem. Even minimal input is enough to start the analysis.
Database & Query Analysis
I analyze SQL queries, execution plans (EXPLAIN), joins, indexes, and data access patterns to identify performance bottlenecks and inefficient operations.
