Enterprise Application Modernisation & Cloud Transformation

Enterprise ArchitectureCloud MigrationAWSGCPAzure

Problem

A financial services organisation needed to migrate 15+ legacy enterprise applications from on-premise infrastructure to the cloud without disrupting mission-critical operations.

Solution

Designed end-to-end cloud migration strategy and target architecture across AWS, GCP, and private cloud. Led application dependency mapping, DR design, production cutover, and cost optimisation.

Impact

Migrated 15+ applications with ~25% infrastructure cost reduction and 99.9% uptime for mission-critical financial systems.

AI-Powered Enterprise Knowledge & Automation Platform

AI ArchitectureRAGLangGraphGenerative AI

Problem

Engineering teams spent excessive time searching documentation, depending on SMEs, and manually resolving incidents — slowing onboarding and increasing operational risk.

Solution

Built an AI-powered enterprise assistant with RAG pipeline, semantic search, multi-agent workflows (LangGraph, MCP), and a Next.js frontend on FastAPI infrastructure.

Impact

Reduced engineering effort through automated knowledge retrieval, faster onboarding, reduced SME dependency, and significantly faster incident resolution.

How I Work

Principles that guide my work

Architecture First

Good outcomes start with clear structure. I invest in architecture because it determines what's possible downstream.

Outcomes Over Outputs

Delivered software is an output. I measure success by the business outcomes it unlocks.

Honest Counsel

Advisory relationships only create value when they're built on trust — including hard truths.

Insights

Latest writing

Technical articles on architecture, cloud, and AI.
