Most people learn Git backwards. They get a list of commands to memorise — git add, git commit, git push — and then spend months not quite understanding why things work or why things go wrong. This post does it differently. It builds the mental model first. Once you understand what Git is actually doing, the commands stop being a checklist and start making sense on their own.
APIs are one of the most targeted attack surfaces in modern software. This post covers the essentials every developer and architect needs to know — API keys, OAuth tokens, rate limiting, input validation, and the OWASP API Security Top 10. A practical reference whether you are building, reviewing, or securing APIs.
REST API design principles have been the foundation of web APIs since 2000 — and they have not changed. This post explains the core principles clearly: resources, HTTP methods, statelessness, status codes, versioning, and idempotency. Whether you are building your first API or reviewing a design, this is the reference you will come back to.
Still deploying your custom SAP Fiori applications by logging into a BTP sub-account and running CF commands manually? It works — until it doesn't. As your landscape grows, so does the risk: no audit trail, no approval gates, no guarantee that what you tested in QA is what lands in production. This guide walks you through the complete setup of SAP Cloud Transport Management Service (CTMS) integrated with the SAP CI/CD Service on BTP — so your Fiori app deployments are automated, controlled, and fully traceable from the moment a developer pushes code to Git, all the way to production. Whether you are setting this up for the first time or refreshing your knowledge of the 2026 toolset, this post covers everything: CTMS subscription and landscape configuration, transport nodes and routes, BTP Destinations with technical users, MTA project structure, CI/CD job setup, and the Release Manager import workflow — with troubleshooting tips and FAQs included.

"I spent 10 years building SAP systems in India, then moved to Helsinki. That shift — between two very different ways of working and living — changed how I think about technology, people, and what good architecture really means."
Previously with Accenture; currently at Vivicta (formerly TietoEvry).
