👩‍💻 About Me

I design and build machine learning, AI, and computer vision systems that solve real-world problems.

My work focuses on:

  • ML / AI Engineering: training, fine-tuning, evaluating, and deploying models with strong reliability
  • Computer Vision: object detection, tracking, pose estimation, video analytics, and medical imaging
  • Agentic AI / LLMs: RAG pipelines, multi-agent orchestration, tool-using agents, prompt design and evaluation
  • Production Systems: Python services, FastAPI APIs, cloud deployment (AWS/GCP), CI/CD, Docker, monitoring

I enjoy taking ideas from research notebooks to production, with explainable behavior and measurable impact.


🚀 What I Build

  • Real-time computer vision pipelines
  • Vision-language model reasoning and evaluation
  • Agentic AI workflows and tool-using assistants
  • Retrieval-Augmented Generation (RAG) systems
  • Medical imaging and intelligent diagnosis platforms
  • ML model training, tuning, benchmarking, and deployment
  • Scalable backend services for AI applications

🔥 Featured Projects

🧠 Visual Agent with Explainable UI Actions

Problem: Automate complex desktop form-filling in a transparent, explainable way.

Impact: Built a computer-use agent that turns UI perception into structured JSON plans and executes precise clicks and typing actions via a perception–reasoning–action loop.

🏙️ Real-Time Pedestrian Analytics

Problem: Detect and track pedestrians across intersections for safety and planning.

Impact: Deployed a YOLOv8 + DeepSORT pipeline over hundreds of scenes, achieving high tracking accuracy and enabling trajectory-based analytics for urban environments.

⚖️ Gender Bias Detection with VLMs

Problem: Measure and explain gender bias in multimodal reasoning models.

Impact: Built an explainable pipeline using LoRA fine-tuned VLMs and Chain-of-Thought reasoning to classify bias with strong accuracy and human-readable rationales.

🤖 StorySprout – Multi-Agent GenAI Storytelling

Problem: Turn structured family memories and lessons into personalized children’s storybooks.

Impact: Designed a multi-agent GenAI platform where a root orchestrator coordinates Safety, Narrative, FactCheck, Pedagogy, Quiz, and Visual agents to produce safe, engaging stories with illustration prompts.

💬 WhatsApp Notification Router – Agentic RAG Workflow

Problem: Classify multimodal WhatsApp messages into notify / digest / mute actions.

Impact: Built an agent-style router combining metadata indexing, OCR, Whisper transcription, hybrid sparse+dense retrieval, rule-based safety filters, and confidence calibration to achieve high action accuracy on realistic message sets.

🩺 Multi-Disease AI Diagnostic Platform

Problem: Build a unified medical imaging pipeline for multiple diseases with interpretability.

Impact: Implemented a platform that supports diagnosis across five conditions, with Grad-CAM-style heatmaps to explain predictions to clinicians and support trust in model decisions.
