About this gig

I build full-stack web applications where the frontend and the AI/ML layer are both done properly not a React shell calling a chatbot API and calling it "AI integration."


  • On the frontend: React 19 or Next.js with Tailwind CSS, clean component structure, responsive across all screen sizes, fast load times.
  • On the backend: Python with FastAPI, JWT-secured REST APIs, PostgreSQL or MongoDB, background scheduling where needed. The backend is production-ready, not a dev-server demo.
  • For AI/ML: I can integrate LLMs (OpenAI, Groq, open-source models via API), build custom ML models (classification, anomaly detection, recommendation), and wire in real data pipelines not just a prompt wrapper.


Recent projects:


  1. QuantLedger: fintech portfolio tracker syncing live prices across 14 asset classes, with a quant risk engine (Sharpe ratio, volatility, cross-asset sensitivity matrix)
  2. NetSentinel: ML-based network intrusion detection system using XGBoost + MLflow + Evidently AI drift monitoring
  3. Spark: LLM-powered project visualization tool using Groq + Supabase + Next.js


Message me before ordering I'll tell you honestly whether your project fits my packages or needs a custom quote.

Full-stack developer building products where React/Next.js meets real AI integration, not an API wrapper but actual ML pipelines underneath. Backend in Python/FastAPI, deploying ML models alongside REST APIs. Recent work – QuantLedger: A fintech portfolio tracker with live market data and quant risk metrics. NetSentinel: An ML-based intrusion detection system using XGBoost with full MLOps tracking (MLflow, Evidently AI). Spark: An LLM-integrated project visualization tool. I scope realistically, communicate clearly, and ship code that holds up past the demo, not just the pitch.
