You will get Backend API Database System
Top Rated
Project details
I build production-ready backend systems using NestJS, Node.js, TypeScript, and PostgreSQL. Your system can include RESTful APIs, secure user authentication, role-based access, clean routing, webhooks, API integrations, and a database structured around how the product actually works.
I pay close attention to software architecture because weak decisions at this stage make future features slower and more expensive.
I also test the parts that are often overlooked, including expired tokens, failed API calls, duplicate webhooks, invalid data, permission gaps, and slow queries.
The backend can support a web application, mobile app, SaaS product, or internal system.
You receive the complete source code, API documentation, setup instructions, and post-launch technical support.
Message me before purchasing so I can review the requirements and confirm the scope.

Flutter Developer Needed for Quotation App with Django/Node Backend
I couldn't be more impressed with the results. From day one, Ahmed demonstrated exceptional technical expertise and professionalism that set him apart from other developers I've worked with. He didn't just code what I asked for but he actively suggested improvements that made the final product even better than I imagined. His API development was particularly impressive, creating seamless communication between the Flutter frontend and Django backend.

UI Enhancement for WordPress Frontend Admin
Ahmed delivered excellent work on my WordPress website, and I truly enjoyed collaborating with him. His communication was exceptional, he met all deadlines, and his skills were solid. At one point, I requested additional work beyond the initial scope, and he was transparent about it being outside his expertise. However, he went the extra mile to help me find the right support for the task. I appreciated his professionalism and dedication, and I am working with him on another project already :)

About Ahmed
Full Stack Developer | Next.js & API Integration

Job Success

Maybe the MVP is live, but every new feature takes longer.
Queries are slowing down. API integrations are breaking.
Payment flows feel fragile. Deployments still depend on manual steps.
The product works, but the codebase is becoming harder to control.
Leaving these problems unresolved makes development slower and more expensive. Small changes create unexpected bugs.
I'm Ahmed, and I step in as a Full Stack Developer and take ownership of the technical outcome.
I identify weak points, choose an architecture that fits your current stage, build the required features, connect complex APIs, deploy the system, and stabilize it for production.
WHAT I CAN OWN
1. SAAS AND MVP DEVELOPMENT
I turn founder requirements into a practical technical plan.
I build the frontend, backend, database, and cloud infrastructure. The goal is to launch quickly without creating a codebase that needs to be rebuilt six months later.
2. NEXT.JS AND BACKEND DEVELOPMENT
I build fast, maintainable applications with Next.js. With a guaranteed 90+ score in Google Page Speed Insights
For backend systems, I use NestJS, Node.js, or Django based on the product requirements.
I handle authentication, permissions, payments, webhooks, background jobs, business logic, and data workflows.
You get a structured codebase that is easier to test, extend, and maintain.
3. API INTEGRATIONS
As an API integration expert, I connect products with payment providers, booking systems, AI platforms, and external services.
I have worked with Stripe, PayPal, Payoneer, live hotel APIs, OpenAI, Meta APIs, MCPs, and providers with inconsistent response structures.
I also handle authentication, retries, rate limits, error handling, webhooks, and data mapping.
4. PERFORMANCE AND AWS
I diagnose the cause of slow or unreliable systems.
This may involve database indexing, query profiling, caching, frontend loading, background processing, or deployment configuration.
I also deploy applications using AWS EC2, RDS, S3, App Runner, Docker, logging, and repeatable release workflows.
MY PROMISE
I do not call a project finished because it works on my machine.
You receive clean code, clear documentation, production deployment, and post-launch support for issues related to my work.
If I fail to deliver an approved milestone according to the agreed scope, I will refund that milestone.
