01 · Who I amAbout

Koushik Deb — professional portrait
🧠 GenAI & Agentic AI
🌏 EN · HI · BN

I wear two hats. By profession I am an AI Engineer and Tech Lead at Accenture, where I design and ship Generative-AI and Agentic-AI solutions for global healthcare clients — proposing new use-cases, building POCs and turning them into deployed products.

In parallel, I am a part-time PhD candidate at IIIT Kalyani (final year), researching bias detection and mitigation in multilingual large language models across English, Hindi and Bengali — how prompts manipulate models, and how to measure and reduce that vulnerability.

Across 13+ years at Accenture, Cognizant, IBM and Capgemini I have built software for Apple, IKEA, Cigna, Roche, Tiffany & Co. and Sanofi. Along the way I picked up three granted patents — from offline NLP on devices to drone-augmented pest control — and a habit of tinkering with ESP32 boards and smart-agriculture hardware on weekends.
