Building intelligent, scalable solutions that bridge technology and real-world impact.
I'm a passionate engineer with a blend of expertise across Data Engineering, AI/ML, and Full-Stack Development. I build robust, enterprise-grade solutions that solve real problems — my work lives at the intersection of data intelligence and practical software engineering.
- 🤖 AI/ML — intelligent agents, LLM apps (MCP servers, Gemini), NLP, sentiment & causal analysis
- 📊 Data — ETL pipelines, text mining, topic modeling, reproducible notebooks
- 💻 Full-Stack — Spring Boot, Next.js/TypeScript, Laravel, modern architectures
- 🏗️ Architecture — multi-tenant systems, RBAC, real-time (WebSocket/CRDT), cloud on AWS
- 🌱 Always learning — advanced AI, DevOps (Docker/Kubernetes), system design
Polished, documented and released — a good place to start.
