Just shipped a full-stack business listing platform — Biziffy.
Built with React/Next.js on the frontend and Node.js/Express on the backend, deployed on a Hostinger VPS (Ubuntu 24.04) with PM2 and Nginx.
Key things I handled on this one:
Google Location API integration for accurate business listings, pincode validation, sitemap and robots.txt setup for SEO, and complete VPS deployment from scratch via SSH.
The part I enjoyed most — getting the deployment pipeline clean so the client could manage updates without developer dependency.

Looking for freelance work (Backend / AI / Full-Stack)
I’m currently open to freelance projects — mainly backend-heavy systems, AI integrations, or full-stack builds.
I’m a Software Engineer working with Java (Spring Boot), Python, and SQL, and I’ve built systems that are already used in real environments (not just demos).
Some of the work I’ve done:
• Built AI-powered document processing systems (LLM + FastAPI + validation pipelines) to extract and structure data automatically
• Developed a financial AI chatbot (RAG-based) that answers queries using real documents and reduces manual workload
• Created a real-time network anomaly detector using Python (Scapy + Suricata) for monitoring suspicious traffic
• Built API integration middleware (Java Spring Boot) connecting multiple systems with retry logic and structured logging
• Developed a smart inventory system with analytics (Node.js + PostgreSQL + MongoDB) used for tracking stock and sales trends
• Implemented ETL pipelines for data migration and reporting (Python + SQL + Pandas)
• Built an automated web security scanner detecting SQLi/XSS issues before deployment
• Worked on computer vision models for defect detection and image classification (CNN + TensorFlow)
• Developed full-stack apps (Flask / FastAPI + React) with real-time API integrations
I’ve also worked in enterprise environments, handling:
production deployments
debugging live systems
API integrations across teams
working with international clients
What I usually work on:
Backend systems & APIs
AI features (chatbots, automation, document processing)
Data-heavy applications
System integrations
MVPs that need to actually scale
I’m not here to just “build features” — I focus on making systems reliable, usable, and production-ready.
If you need someone who can:
✔️ understand your system
✔️ build fast
✔️ and not break things in production
send me a message.

Wow this is impressive! Nice work!
I work across the full stack—designing and developing AI-powered applications from the ground up. This includes everything from user-facing interfaces to backend systems, AI integration, and deployment. My focus is not just on building models, but on delivering complete, usable products.
Over time, I’ve worked on:
AI-powered chatbots and conversational systems
Generative AI applications using LLMs
Data-driven automation workflows
AI-enhanced search and recommendation systems
