Project details

You will get a fast, reliable fix for your API, backend, or database issue. I specialize in diagnosing production problems, tracing root causes, and delivering clean, stable solutions that hold up under real-world load. Whether your system is timing out, returning inconsistent data, failing under traffic, or throwing unclear errors, I’ll identify the bottleneck and resolve it with clarity and precision.

My process is simple: understand the symptoms, reproduce the issue, isolate the failing component, implement a clean fix, and verify the results. You receive a stable system, a clear explanation of what went wrong, and actionable recommendations to prevent recurrence.

This service is built for teams who need a senior engineer’s insight without the overhead or delay—fast turnaround, clear communication, and production-grade work.

About Nissim

Eatontown, United States - 8:09 pm local time
I specialize in backend/API glue work: securing webhooks, building serverless endpoints, normalizing messy data, handling auth (OAuth2/API keys), and building API integrations no-code tools can’t handle.

I’m offering introductory pricing while I build visible social proof here.

Steps for completing your project

After purchasing the project, send requirements so Nissim can start the project.

Delivery time starts when Nissim receives requirements from you.

Nissim works on your project following the steps below.

Revisions may occur after the delivery date.

Review Your Requirements & Reproduce the Issue

I analyze your description, logs, screenshots, and access details. Then I reproduce the failure locally or in your environment to fully understand the behavior.

Diagnose the Root Cause

I trace the problem through logs, API behavior, database queries, performance metrics, and recent changes. You get clarity on exactly why the system is failing.
