What I'm looking for

I'm looking to build AI-powered and backend products where I can lead delivery, integrate machine learning into production systems, and solve complex data and automation problems.

I'm building crop-identification AI at Arya.ag using OpenAI GPT-4, PGvector, and retrieval-augmented generation to handle intelligent queries. I also own backend development, satellite-data visualization, geolocation mapping, and farmer activity workflows.

I've integrated machine learning components into production APIs, implemented Google Sign-In and role-based access control, and collaborated with Java teams on microservices and Dockerized deployments.

Previously, I led cross-functional delivery at Nethues Technologies and development teams at Arkss Technologies, improving database schemas, queries, application reliability, and large-scale data systems.

My hands-on work spans fine-tuning Mistral-7B with QLoRA, building local GPT-2 training tools, developing knowledge-augmented chatbots, and delivering Django, Laravel, React, Flutter, embedded, and automation projects.
