À propos de moi
I build production AI agents and RAG chatbots with Claude Code and Python, AI document-extraction pipelines (OCR), and cross-platform mobile apps with Flutter - including a real restaurant reservations app rolling out on Google Play, the App Store and web via AWS. Verified results: 92.85% ROC AUC churn model, Prophet R2 = 0.80 on 160K+ listings, SVM 86% on 4M+ reviews, across 20 portfolio projects. My promise: honest scoping before you order, plain-English answers, fast replies, and code you own outright.

IT Manager
Self Level • Temps plein
Apr 2004 - Present • 22 yrs 3 mos
IT Manager at MARSS Group Pvt Ltd, an auto-parts supply and manufacturing company. I own the IT infrastructure end to end: network administration, system operations, user support, and technology strategy for day-to-day business operations. Two decades of keeping business-critical systems running shapes how I build AI systems as a freelancer today — I scope realistically, design for uptime, logging and security from day one, and hand over solutions a client's own team can run without me.
