About this gig

I will optimize your website performance and fix backend bottlenecks to improve speed, stability, and scalability.

If your website loads slowly, APIs respond with high latency, or database queries are inefficient, I will analyze the root cause and apply proper optimization strategies. This includes SQL query tuning, indexing improvements, pagination optimization, and backend performance fixes.

I focus on clean, production-ready solutions not temporary patches. The goal is to reduce response time, improve user experience, and ensure your system runs efficiently under real traffic.
