Prompt Design & Optimization

Craft structured prompts that improve accuracy, tone, clarity, consistency, and task performance across chatbots, assistants, summarizers, and AI workflows.

LLM Behavior & Response Control

Guide models such as GPT, Claude, Gemini, and open-source LLMs using system instructions, few-shot examples, prompt chaining, and output formatting strategies.

Tool Use & Function Calling

Design prompts that enable AI systems to call APIs, trigger tools, schedule actions, retrieve documents, update CRMs, and interact with external systems.

Memory & Context Structuring

Create prompting strategies for single-turn and multi-turn interactions, including context retention, summarization, memory injection, and continuity across workflows.

Safety, Guardrails & Filtering

Implement prompt-level controls that reduce hallucinations, off-topic outputs, unsafe responses, and inconsistent behavior through better instructions and fallback design.

 

Domain-Specific Prompt Systems

Tailor prompts for industries such as legal, healthcare, education, HR, e-commerce, and customer support with the right tone, logic, and vocabulary for each use case.

Bird Disease Classification (MLOps)

Built an end-to-end deep learning MLOps pipeline for bird disease classification using TensorFlow/Keras, PyTorch, OpenCV for image processing, FastAPI for model serving, and Docker for containerization. Implemented automated training pipelines, model versioning, and deployment workflows.

U.S. Visa Approval Prediction (MLOps)

Developed a complete MLOps pipeline for visa approval prediction using Python, FastAPI, Docker, AWS (EC2, ECR, S3), XGBoost, and CatBoost. Implemented automated model training, versioning, deployment, and monitoring with CI/CD integration for production-grade machine learning.

Uber Data Analytics Pipeline

Built a robust time-series forecasting solution with over 90% accuracy using Python and statistical modeling.
It enabled a growing online retailer to better manage inventory, reduce overstock, and forecast seasonal demand shifts.

CareSage - RAG Medical Chatbot

Developed an intelligent medical chatbot using Retrieval-Augmented Generation (RAG) with Flask, LangChain, Pinecone vector database, OpenAI embeddings, and sentence-transformers. The system processes medical PDFs using PyPDF to provide accurate, context-aware responses for healthcare queries with citation support.

n8n Workflow Automation

Built 8 comprehensive automation workflows using n8n platform integrated with Retell AI, GoHighLevel, Twilio, OpenAI GPT-4, and PostgreSQL. Projects included AI Voice Agent for customer service, Multi-Channel Communication Hub, Lead Qualification System, CRM Sync Automation, Content Generation Pipeline, Customer Onboarding Workflow, Voice-Based Appointment Scheduler, and BI Reporting Dashboard.
