🧠 About Me
I'm a hands-on architect and product strategist passionate about building intelligent, scalable, and modular systems.
With deep expertise across Spring Boot, Node.js, and AI-based architectures, I bridge the gap between product vision and engineering execution.
I love designing systems that are:
- ⚙️ Robust and maintainable — crafted with clean architecture
- 🤝 Composable and scalable — designed for distributed teams and services
- 🧩 Smart and adaptive — powered by automation, ML, and modern DevOps
- 🔭 12+ year of experience working with all sort of clients & technologies.
- 🔭 I’m currently working on enhancing my skills in Kubernetes and server management.
- 🌱 I’m currently learning more about cloud-native architectures and microservices.
- 💬 Ask me about software architecture, CI/CD pipelines, or anything related to Node.js and React.

🏗️ Projects & Work Highlights
🔹 AI-Enabled CCTV Security System
YOLOv5, OpenCV, Flask, SmolVLM
Built a real-time AI system for vehicle plate recognition, violence detection, and threat analysis.
Integrated vision-language models (VLM) for contextual live video understanding.
🔹 RAG-based Educational AI Assistant
Node.js, PostgreSQL, Vector DB, ChatGPT API
Developed a Retrieval-Augmented Generation (RAG) API that provides personalized study responses from PDFs and markdown notes.
Structured as API-first, tested via Postman, ready for mobile app integration.
🔹 OAuth2 Authorization Server (Spring Boot 3.2)
Designed a production-ready OAuth2 JPA-based authorization server with support for:
- Client registration
- Token & refresh token lifecycle management
- User approval flows
- Role-based authorities
🔹 Notification Workflow Engine
Integrated Camunda/Flowable BPMN for email notification tracking and inter-service event flow (e.g., payment triggers).
🔹 Fintech & Social Media Platforms
Built prototypes for:
- A loan distribution app for the Indian market
- A cross-platform social posting system with long-lived OAuth tokens for Facebook, X, and LinkedIn
☁️ DevOps & Architecture Highlights
- 🏗️ Designed microservice blueprints with secure inter-service authority sharing (non-HTTP access).
- 🔒 Centralized CORS and gateway security using Spring Cloud Gateway.
- 🧰 Implemented AWS IAM role-based access model: Root, Developer, Management, and Support roles.
- 🚀 Built reverse proxies for Solr and internal APIs to improve reliability and access control.
💡 My Engineering Philosophy
“Build systems that are simple at the surface, powerful at the core, and scalable for the future.”
- 🧩 Architecture First → clarity before code
- ⚡ Automate Everything → efficiency through scripting and workflows
- 🤖 AI by Design → integrate intelligence at every level of the stack
- 🧠 Learn Relentlessly → always exploring emerging tech like LLMs, Rust, and privacy-first AI
🛠️ Current Interests
- 🦀 Learning Rust for system-level performance and AI inference
- 🧠 Exploring local LLMs (Ollama) and open-weight VLMs (SmolVLM, Mistral, Phi-3)
- 🔍 Building privacy-preserving, explainable AI architectures
- 🔔 Workflow-based automation using Camunda or Flowable embedded in Spring Boot
