01 / About
I'm Ajay, an AI/ML engineer and M.Tech student at IIT Hyderabad.

I build perception and multimodal AI: from sonar and near-infrared object detection for autonomous vessels, to vision-language models, to LLM systems that retrieve, reason and respond.
Over 2+ years across three IIT Hyderabad labs, I've built datasets from scratch, fine-tuned VLMs and published my research at IEEE.
I engineer computer vision, vision-language and agentic AI, taking sensor data through fine-tuned models to systems that perceive, reason and act, and I lead that work from plan to delivery.

04 / Experience
Sep 2024 – Jul 2025
LFOVIA Lab, IIT Hyderabad
Evaluated and fine-tuned vision-language models (Florence-2 Base/Large, Llama 3.2 Vision and Qwen2-VL) for multimodal text-image understanding, and benchmarked task-specific models including RetinaFace, DeepFace and Siamese architectures for targeted detection, face analysis and visual tracking / re-identification.
Nov 2023 – Jul 2024
TIHAN, IIT Hyderabad
Worked on multimodal maritime perception: developed and curated near-infrared and sonar datasets, and built sensor-specific preprocessing, annotation, data-quality and model-training pipelines for robust object detection in complex maritime environments, resulting in an IEEE conference publication.
Jul 2023 – Nov 2023
WINET Lab, IIT Hyderabad
Built foundational sonar-based underwater object-detection datasets with annotation, Python preprocessing, data augmentation and markup pipelines to improve data quality and model robustness. Published at IEEE i-COSTE 2023.

Exploring how vision-language models and agentic systems can give autonomous systems and edge AI a higher-level, semantic understanding of the world.
08 / Beyond the lab
Curiosity does not stop when the lab closes. I build things for fun, learn from people who have gone further than me, and I am deeply curious about Japan, its language and its design.
