What I'm looking for

I'm looking to build production full-stack and AI-enabled products where I can work on REST APIs, data systems, LLM integrations, and scalable multi-tenant applications.

At Stemphor Techlabs, I build full-stack features for multi-tenant web and WhatsApp bot systems, from React and Express workflows to AWS S3 and MySQL.

I've built SEO infrastructure with JSON-LD, Open Graph and GA metadata, admin-managed configuration, and Nginx-routed dynamic sitemaps. I also integrated business-specific FAQ handling into an LLM-driven intent-classification flow without adding a second model call.

I resolve cross-service authorization and SQL data-integrity issues across voucher and promotion systems, while building audit logging, admin review tools, and audience targeting for WhatsApp promotions.

Outside client work, I've built a Python anomaly detection project that improved accuracy by 25% and reduced manual effort by 40%, a Django fitness tracker, and a RAG-based customer support AI agent using Langflow, Astra DB, and Gemini.
