What I work on
Engineering across the whole system.
I’m Ahmad Sadieh (s3dyeh), a software, full-stack and AI engineer. My work connects interfaces, backend services, databases and AI capabilities. Explore the areas below for my approach and related project experience.
Angular, TypeScript and Node.js applications
I build and improve frontend and backend applications, including existing codebases that need debugging or modernization. My core stack includes Angular, TypeScript, Node.js, NestJS and Express, supported by REST APIs, authentication and role-based access.
LLMs, RAG and AI agents
I integrate AI capabilities into products and enterprise workflows, including knowledge assistants, retrieval-augmented generation and agents. My toolkit includes FastAPI, LangChain, OpenRouter and Ragas, with attention to the application’s data, access requirements and evaluation.
Oracle, PostgreSQL and REST API performance
I trace slow APIs, expensive queries and integration problems across the frontend, backend and database. The work starts with understanding the existing architecture and the affected workflow, then making a focused change and checking the result.
Deployment and production preparation
Docker, Google Cloud, authentication and authorization are part of carrying an application toward production. My project work includes deployment and maintenance as well as feature development, with attention to maintainability and clear architecture.
