Hello there, I am Rizwan Ahmad Khan, a results-driven software engineer with 14+ years of experience in building scalable, secure, and innovative solutions across web, mobile, and backend platforms.

I started my journey in tech with a strong curiosity about how things work — from writing my first lines of code in Java to leading teams that deliver enterprise-level solutions. Over the years, I’ve worked with technologies like NestJS, Node.js, Angular, React Native, Python, and Django, while also diving deep into DevOps practices with Docker, Jenkins, and AWS.

In recent years, I’ve been exploring the power of Artificial Intelligence by integrating OpenAI’s GPT models into real-world applications — building features like chatbots, document summarization, and semantic search using embeddings and vector stores. This fusion of traditional backend expertise with next-gen AI tools excites me the most, as it opens endless opportunities to create smarter, user-centric applications.

Beyond coding, I enjoy problem-solving and mentoring — helping teams grow and turning complex challenges into streamlined solutions. My philosophy is simple: technology should empower people, simplify processes, and create value.

When I’m not coding or experimenting with new frameworks, you might find me reading about emerging tech trends, AI innovations, or exploring creative problem-solving techniques.

Recently, I have been working extensively on OpenAI GPT model integrations, implementing AI-powered features such as document summarization, chat interfaces, and semantic search using embeddings and vector stores. In my free time, I love tinkering with embedded systems and Raspberry Pi DIY projects, always experimenting and learning something new.
