About Me

I'm a Senior AI Engineer focused on production RAG systems, LLM infrastructure, and multi-agent orchestration, with 3+ years of end-to-end ownership across AI integration, scalable backend architecture, and full-stack delivery. I enjoy turning ambiguous product ideas into reliable systems that are fast, observable, and genuinely useful in production.

My work spans LangChain, LangGraph, LlamaIndex, OpenAI APIs, Hugging Face, LangSmith, vector search, and modern frontend delivery with Next.js and TypeScript. I care a lot about strong architecture, prompt and retrieval quality, observability, cost optimisation, and shipping AI features that hold up under real usage instead of only looking good in demos.

When I'm not in full-on developer mode, you can find me hovering around on Instagram, Linkedin, or on Youtube, following early-stage product journeys, experimenting with new AI workflows, or refining the systems thinking behind the next thing I want to build.

    CinemaView is a free cinema seat simulator that lets you preview exactly how the picture looks from any seat — online, in your browser, before you spend money on tickets. Unlike flat seat maps on booking sites, CinemaView places you inside a procedurally generated auditorium built to realistic dimensions. You sit in first-person view, drag to look around like a real patron, and switch between Standard, IMAX, Dolby Cinema, ScreenX, and 4DX to see how premium formats change the experience.
