What I'm looking for

I’m looking for a role where I can build generative AI (including production-ready AI agents) and integrate it into full-stack web products. I value early prototyping, measurable outcomes, and collaboration with teams that move fast.

I’m an AI Engineering and full-stack development professional focused on turning business problems into working solutions through Generative AI and interactive web applications. I build systems that connect AI capabilities to real user needs, with an emphasis on measurable impact and practical delivery.

In my work as a Freelancer, I designed and developed high-conversion landing pages and web interfaces using HTML, CSS, and JavaScript. I also reduced the interface development cycle time by ~30% by creating interactive prototypes and validating requirements early with Figma, while managing projects end-to-end from discovery to delivery.

Currently, I’m supporting process and data improvement as an Administrative Assistant, managing daily operational data to strengthen accuracy and decision-making. Alongside experience, I’m actively developing my AI expertise with production-ready agent and model customization courses (e.g., Amazon Bedrock Agents and Amazon SageMaker), plus ethics and AI fundamentals.
