Who I am

I'm a full-stack software engineer with deep experience across generative AI, Django/Python backends, cloud infrastructure, and mobile development with Flutter.

I have a passion for building systems that impact people. I'm always researching new areas to expand my reach and put my skills to use — bringing the best products to clients and consumers.

Recently I've been finetuning large language models, building voice-call solutions between clients and AI agents, and shipping AI agent integrations to platforms like Discord, Slack, WhatsApp and Webex.

Willing to relocate: anywhere.
