I specialise in AI-driven software engineering using Python, JavaScript, and AWS, building everything from fast APIs to full end-to-end SaaS platforms. Front-end to back-end, I turn ideas into smooth digital experiences. SQL or NoSQL — I design and optimise databases that run clean and handle real load. APIs & automation — I build scalable REST services and workflow automation that keep products running smoothly. My approach is simple: engineer clean systems, automate the boring parts, and make everything feel seamless in the real world — from the UI to the database to the cloud. Over the past few years, I’ve been working hands-on with AI across practical, production-ready use cases: chatbots, trading bots, analytics tools, talking avatars, object detection, and image generation. My focus is always the same - making AI engine that actually get used, make sense, and deliver value to the product. Whether it’s Python microservices, JavaScript front-ends, AWS cloud architecture, or building a full SaaS system from scratch, I aim for clean engineering and a result that feels remarkable in the real world.
