🧑‍💻 About Me

I build production-grade full-stack applications that combine .NET microservices, Angular frontends, and Python ML pipelines. My projects span e-commerce intelligence, InsurTech, real-time financial systems, and computer vision — all with real metrics and deployed models.

  • 🏦 Finance-aware engineer with a Minor in Financial Markets — built production FinTech systems (credit risk, real-time market intelligence, RAG pipelines) not just tutorials
  • 🏗️ Comfortable with Clean Architecture, microservices, event-driven systems (Kafka), Docker, CI/CD
  • 🤖 Shipped 10+ ML models in production — from XGBoost & LSTM to FinBERT and transfer-learning CNNs — across FinTech, e-commerce, and computer vision
  • 📊 Data Science background with RAG pipelines, NLP, Computer Vision, and time-series forecasting
  • 🔨 Currently building StreamPulse — a Kafka-based real-time financial platform, now in AWS deployment
  • 🎯 Actively targeting roles in ML Engineering · AI/ML Full Stack · Data Science

🚀 Featured Projects

🏗️ Full-Stack Platforms

⚡ StreamPulse — Real-Time Financial Intelligence Platform 🚧 In Progress

Apache Kafka · ASP.NET Core 10 · Angular 21 + PrimeNG Aura · Python FastAPI · TimescaleDB · Redis · SignalR · Prometheus + Grafana · AWS EC2

Event-driven platform processing live stock ticks through Kafka, with Python ML microservices for LSTM price forecasting, Isolation Forest anomaly detection, and news sentiment analysis — delivered to an Angular dashboard in real time over SignalR WebSockets, with full observability via Prometheus + Grafana.

  • 🏗️ 12 services across .NET, Python & Angular, communicating through 4 Kafka topics
  • 📈 Live candlestick charts, real-time ticker, and severity-based alerting with email notifications (Gmail SMTP via MailKit)
  • ✅ 15 end-to-end integration tests (NUnit + FluentAssertions) tracing the full data pipeline
  • 📊 Prometheus scraping all 7 services into a 7-panel Grafana monitoring dashboard
  • ☁️ Currently deploying to AWS EC2, with GitHub Actions CI/CD up next

🛍️ ShopSense — AI-Powered E-Commerce Intelligence Platform ✅ Completed

Angular 21 · ASP.NET Core 10 (6 microservices) · 6 Python FastAPI ML services · Ocelot · Docker (17 containers) · SQL Server · Redis · RabbitMQ

21-day build. Full e-commerce platform with a complete AI intelligence layer — recommendations, dynamic pricing, churn prediction, sentiment analysis, demand forecasting, and fraud detection.

Model Algorithm Metric
Sentiment Analysis TF-IDF + Logistic Regression 96.68% accuracy
Churn Prediction XGBoost ROC-AUC 0.9857
Demand Forecasting Holt-Winters MAPE 42.9%
Dynamic Pricing Gradient Boosting R² 0.47

🤝 NexHire — AI-Powered HRMS

Angular 21 · ASP.NET Core 10 (3 microservices) · Groq API (Llama 3.1-8b) · Docker · GitHub Actions CI/CD

Built in 5 days for the FWC IT Services hackathon. AI-assisted recruitment, employee management, and performance evaluation with LLM integration via Groq.


🏥 SmartSure — Enterprise Insurance Management System

Angular 21 · ASP.NET Core 10 (4 microservices) · Clean Architecture · Razorpay · RabbitMQ · MailKit OTP · Docker

Production-grade InsurTech platform covering policy management, claims processing, fraud detection, and payment integration. Includes 117 NUnit tests with 90%+ coverage.


🧠 ML / Data Science Projects

💳 CreditIQ — FinTech Credit Risk Intelligence

FastAPI · XGBoost · FinBERT · PyTorch LSTM · SHAP · Streamlit · Docker

253 features engineered from 307K+ loan records. 4-model calibrated ensemble with SHAP explainability, FinBERT news sentiment scoring, and LSTM 12-month default forecasting.

XGBoost ROC-AUC: 0.7875 · FinBERT F1: 98.45% · 🌐 Live Demo


🍊 Orange Defect Detection & Classification

Python · OpenCV · Scikit-learn · PyTorch (MobileNetV2 transfer learning) · LBP/GLCM texture features

4-class citrus quality-control pipeline (Greening, Canker, Black Spot vs. Fresh), built as a real assignment for Green Pod Labs. Two independent approaches — a handcrafted classical CV pipeline and a transfer-learning CNN — are trained and compared head-to-head on the same held-out test set, with pixel-level spoilage estimation and a packhouse-ready demo script.

  • 🧪 Classical pipeline (HSV/Lab color + LBP/GLCM texture + Random Forest): macro-F1 0.954
  • 🧠 MobileNetV2 + MLP head (frozen backbone): macro-F1 0.955
  • 🩹 Pixel-level spoilage % estimation per defect class, validated with a healthy-fruit sanity check
  • 📄 Full written report covering EDA, class-imbalance & background-bias mitigation, and deployment trade-offs

📚 FINsight RAG — Financial Document Intelligence

Anthropic Claude · HNSW Vector Indexing · Agentic Pipeline

RAG pipeline with HNSW vector search and an agentic Decompose → Retrieve → Synthesise workflow for intelligent financial document Q&A.
