Who I am

I am a Full-Stack Software with a deep passion for building intelligent SaaS platforms, scalable backend integrations, and AI-driven automation workflows that solve complex engineering challenges.

My Engineering Approach

I believe that great software is built at the intersection of robust architecture and cutting-edge AI. My focus is on writing clean, maintainable code, architecting resilient CI/CD pipelines, and integrating Large Language Models (LLMs) securely into production environments.

  • AI-Powered Features: RAG pipelines, document-ingestion systems, and AI FAQ agents using LangChain, pgvector, and Cohere Embeddings.
  • SaaS & Integrations: Multi-tenant platforms, RBAC systems, billing engines, and channel integrations (WhatsApp, Messenger, Shopify) from design to deployment.

Tech Stack & Tools

Languages & Frameworks: TypeScript, JavaScript, C#, Node.js, NestJS, Express.js, ASP.NET, React, Next.js
AI & Integrations: LangChain, RAG, pgvector, Cohere Embeddings, n8n, Shopify API, Paymob
