I build two things businesses at scale need most right now: intelligent automation systems and production-grade ML/data pipelines. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📊 DATA ANALYTICS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Data analysis and business intelligence using Python, SQL, and Tableau. • SQL analytics — MySQL and SQLite for complex queries, joins, aggregations, cohort analysis, and reporting pipelines • Exploratory data analysis (EDA) — datasets from 25K to 850K+ records, outlier detection, encoding, correlation analysis • Tableau dashboard development — interactive KPI dashboards, customer segmentation views, market trend visualizations • Web scraping pipelines — Selenium and Playwright for dynamic site extraction (Notion, e-commerce, industrial sites) • Market basket analysis and retail analytics on 400K+ transactions • Business KPI design, risk frameworks, and retention strategy Data stack: Python · Pandas · SQL · MySQL · SQLite · Tableau · Matplotlib · Seaborn · NumPy · Selenium · Playwright ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚙️ PYTHON & MACHINE LEARNING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Python machine learning development for classification, regression, clustering, and deep learning using Scikit-learn, TensorFlow, and Keras. End-to-end ML pipelines — data ingestion, cleaning, feature engineering, model training, evaluation, and deployment-ready outputs. Delivered projects: • Churn prediction model — 90.9% accuracy on 850K+ records • Credit risk model — recall improved from 32% to 71% using Random Forest, SVM, KNN, and Neural Networks on 30K+ records • Visa approval prediction — EDA + classification pipeline at ~76% accuracy • IEEE-published Transformer model for industrial fault diagnosis (Dec 2021) Python stack: Pandas · NumPy · Scikit-learn · TensorFlow/Keras · Matplotlib · Seaborn · Jupyter Notebook · SQLite · Django · Flask ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🤖 AI AUTOMATION & AGENT DEVELOPMENT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ n8n workflow automation and AI agent development connecting LLMs, APIs, databases, and business tools into fully automated pipelines. Systems I build: • AI inbound receptionist — 24/7 lead capture, FAQ handling, appointment booking without human involvement • Speed-to-lead automation — AI-personalized outreach firing within 60 seconds of form submission via email, SMS, or WhatsApp • Lead reactivation systems — GPT-powered drip sequences re-engaging cold leads with personalized messaging • AI hiring & CV screening — automated parsing, scoring, shortlisting, and interview scheduling pipelines • Content generation pipelines — AI-written social, ad, and email copy auto-populated into Notion or Airtable content calendars • CRM automation — SharePoint, Power Automate, Airtable, HubSpot workflows eliminating manual data entry Automation stack: n8n · OpenAI API · Claude API · Webhooks · REST APIs · Twilio · Gmail API · Google Sheets · Airtable · Notion · Make (Integromat) · SharePoint · Power Automate · Python scripting ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎓 CREDENTIALS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • IIT BHU Varanasi — IDD BTech + MTech, Mining Engineering (CGPA 8.63) • IEEE Research Publication — Transformer model, Dec 2021 • IIM Ahmedabad — Analytics for Business Problem Solving • IBM — Product Management Certification • HackerRank — SQL Intermediate + Problem Solving Certified • Udemy — Python for Data Science and ML Bootcamp • Neural Networks and Deep Learning (AI) Certification ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✔️ KEY SKILLS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Python · Machine Learning · Deep Learning · TensorFlow · Scikit-learn · n8n Automation · AI Agent Development · OpenAI API · REST API Integration · SQL · MySQL · Data Analysis · Tableau · Data Visualization · EDA · Feature Engineering · Web Scraping · Selenium · Playwright · SharePoint · Power Automate · CRM Automation · Pandas · NumPy I work with startups, agencies, and mid-size companies who need reliable technical execution — not just consultation. Clear communication. On-time delivery. Built to hand off. Open to fixed-price projects, hourly contracts, and long-term retainers.
