I will optimize your nodejs API performance and database queries
Farhad Ali
Sobre este Serviço
Stop Losing Users to Slow Loading Times! Is your API lagging? Are your database queries taking seconds instead of milliseconds? I specialize in high-performance backend engineering.
What I offer:
- Deep API Benchmarking: I use industry-standard scripts (tsx/npx) to profile every operation.
- Database Optimization: Identifying N+1 issues, missing indexes, and slow joins.
- Dockerization: Setting up local environments that mirror production for pinpoint debugging.
- Bottleneck Analysis: Determining if your issue is Network Latency, Cold Starts, or inefficient Code.
My Recent Success: Reduced a Student Management API's response time from 1.7 seconds to 6 milliseconds using optimized local DB architecture.

Perguntas frequentes
What information do you need to start the benchmark?
To get precise results, I typically need access to your repository (Node.js/TypeScript preferred) and a connection string to a staging or development database. If you prefer not to share access, I can provide a benchmarking script for you to run locally and send me the logs.
Can you optimize my API without changing my Database provider?
Absolutely. While I often find that "Cold Starts" or "Serverless" tiers cause latency, many speed issues come from missing indexes, N+1 query patterns, or heavy serialization. I focus on optimizing your code and query structure first.
Will you perform the optimizations on my live production server?
Never. I follow a strict "Safety First" protocol. I replicate your environment using Docker or a staging branch to identify bottlenecks. Once the improvements are benchmarked and verified, I provide the optimized code or migration scripts for you to deploy.
My API is fast locally but slow for users. Can you fix this?
Yes. This usually indicates a Network Latency or Geographic Routing issue. I will analyze your server-to-database "Wall Time" vs. internal execution time to determine if you need a better VPC configuration or a different deployment region.
What tools do you use for benchmarking?
I use a custom suite of high-precision scripts (typically using tsx, autocannon, or k6) that measure the full lifecycle of a request: Authentication, Route Parsing, DB Fetching, Serialization, and JSON Payload delivery.
Do you support databases other than PostgreSQL/MySQL?
Yes, I can optimize any SQL-based database (PostgreSQL, MySQL, SQLite, SQL Server) as well as NoSQL options like MongoDB. My focus is on the logic between your API and the data layer.
Will I get a report of the "Before" and "After" results?
Yes. Every "Standard" and "Premium" package includes a detailed Performance Comparison Table (similar to my gig gallery) showing the exact millisecond improvements for every operation tested.
