Ahmed A.

You are here because your product is no longer as simple as it was on Day 1. 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.
