Solution architect: SAP BTP, integration and AI
Solution architect and technology lead with 9 years in SAP and enterprise platforms. I design platforms end to end (architecture, data, integration, security and delivery) and lead the teams that build them: SAP BTP and CAP at Cellnex, and now AI services for mobile-network engineering at Cyient. Outside work I build AI agent systems: multi-model orchestration, MCP tools and local models.
Selected builds
Two things I built on my own time, both running live.
Not So Fast AI
Multi-model AI orchestrator
A multi-model AI orchestrator: it classifies every task and sends it to the cheapest model that can do it, from local models to Claude, then reviews the result. It built most of these sites and apps.
Job Hunter
Local AI job matcher
Collects job offers from public job APIs, ranks them against my profile with a local LLM and drafts a tailored CV and cover letter for the best matches.
