Achievements & impact

Selected outcomes from enterprise AI, multi-agent systems, and production GenAI.

Credit approval AI

Intelligent multi-agent risk analysis for banking — external signals (news, competitors, financials) integrated into workflows. ~60% faster risk assessment and stronger decision quality. Architected cost-optimised LLM usage (~30% token savings).

Code modernisation agents

Multi-agent orchestration with LangGraph for large-scale modernisation — reverse and forward engineering at scale. Transformation timelines reduced from ~2 years to ~6 months (~75%).

Multi-agent SDLC platform

Centralised AI-powered SDLC platform for 200+ users — adopted across Orion Innovation for standardisation, automation, and efficiency.

Security & debugging agents

Enterprise-grade AI security and debugging agents — org-wide adoption, ~20% reduction in production defects, improved reliability.

Customer-service AI

Integrated AI into customer service — ~35% efficiency uplift. Low-latency RAG pipelines with sub–3s response targets.

Risk prediction engine

Advanced ML/DL for maritime risk — ~30% improvement in predictive accuracy.
