I grew up building things — web apps, data pipelines, dashboards — before moving into business analysis and solution design. 10+ years helping non-tech companies modernize their IT by bridging stakeholders who think in processes with teams who think in systems.

Aiming for Enterprise Architecture
next
what i'm working on now
Building
– Composable eCommerce architecture at TCS — middleware selection phase
– Iterating on my template-app: adding OpenTelemetry observability layer
– This website (Astro + React, deployed on Vercel)
Learning
– TOGAF Foundation — self-study, exam planned Q2 2026
– Deepening Java/Spring Boot through personal projects
– ArchiMate notation for enterprise architecture modeling
Reading
– "Fundamentals of Software Architecture" — Mark Richards & Neal Ford
– "Building Evolutionary Architectures" — Ford, Parsons, Kua
– Re-reading "Enterprise Integration Patterns" — Hohpe & Woolf
Thinking about
– How AI agents will change the solution architect's role
– Whether TOGAF is still relevant or if lighter EA frameworks are better
– The gap between SAP architects and cloud-native architects — and how to bridge it
