SAP BTP foundations
Subaccounts, entitlements, Cloud Foundry vs Kyma, destinations, connectivity and the org model — the parts every project gets wrong in week one.

About
I design systems wherenothing is allowed to slip —and write about people who did.
SAP BTP Solution Architect and SAP Certified Professional designing and delivering enterprise-grade cloud applications across manufacturing, procurement, finance, sales, commercial and healthcare — with AI-assisted engineering woven into how the work actually gets shipped.
Currently leading solution architecture and technical delivery across nine concurrent SAP transformation initiatives for a leading chemical manufacturing client, driving cloud-native application development, stakeholder collaboration, Agile delivery and enterprise modernisation.
By day
Architect cloud-native SAP applications and run the delivery around them — design reviews, estimates, release plans, mentoring.
By night
हिन्दी में लिखते हैं — उन लोगों के बारे में, जिनसे ज़िंदगी में कहीं कुछ छूट गया।

Four columns, one job: get enterprise software into production without breaking the core. Everything here is something I have shipped, not something I have read about.

BTP LearningHub
SAP BTP, explained by someone who ships it on Monday.
Most SAP BTP material is either a 400-page official guide or a two-minute video that skips the hard part. BTP Learning Hub sits in between — production-grade walkthroughs written from live enterprise delivery, in plain language, with the mistakes left in.

What you will find inside
Six learning tracks, each written from something that actually shipped.
CAP (CAPM) end to end
From `cds init` to a deployed MTA: CDS modelling, services, custom handlers, authorisation, HANA Cloud persistence and multitenancy.
Fiori & SAPUI5 in practice
Freestyle vs elements, OData V2/V4 realities, performance patterns, Launchpad/WorkZone integration and Fiori design-guideline compliance.
Integration & events
Integration Suite iFlows, Event Mesh topics, API Management policies and how to keep S/4HANA extensions on the clean side of Clean Core.
AI-assisted engineering
How GitHub Copilot, Claude Code, SAP Joule and SAP AI Core actually change a delivery sprint — prompts, guardrails, review discipline and what not to delegate.
Architecture & career
Clean Architecture and SOLID applied to BTP codebases, estimation, design reviews, certification routes and how to move from developer to architect.
Who it is for
ABAP & functional folks moving to cloud
A route into BTP that does not assume you already write JavaScript.
UI5 / Fiori developers going full-stack
CAP services, HANA Cloud and deployment — the half of the job most UI developers never get shown.
Architects and leads
Reference patterns, Clean Core decision trees and reviewable checklists you can drop into a design workshop.
Certification candidates
Structured prep for the Fiori Developer and Extension Suite exams, written by someone who holds both.
Why it exists
Written from live enterprise delivery, not from the documentation index
Every walkthrough is something that shipped to a real production tenant
Plain English first, jargon second — with the failure modes included
Built and maintained solo on the MERN stack, so it stays fast and ad-free
Free to read. No paywall, no gated PDF, no sign-up to see a tutorial

लेखक
एक लेखक के रूप में विनय
Raised in Ghazipur, living in Noida. He spends the day building systems where every mistake is caught — and the night writing about the ones where it was not.
विनय कुमार तिवारी ग़ाज़ीपुर, उत्तर प्रदेश में पले-बढ़े और आजकल नोएडा में रहते हैं। इंजीनियरिंग (B.E.) के बाद से वे सॉफ़्टवेयर इंजीनियर हैं — बड़े सिस्टम सोचते, उनका ढाँचा खड़ा करते और उन्हें बनाते हैं। उनकी ज़िद एक ही है: जो बने, उसमें कोई कमी न रहे।
दिन में वे ऐसी दुनिया बनाते हैं जहाँ हर ग़लती पकड़ी जाती है और ठीक कर दी जाती है। रात में वे उस दुनिया के बारे में लिखते हैं जहाँ ऐसा नहीं होता — जहाँ कोई फ़ोन नहीं उठाया गया, कोई ट्रेन छूट गई, किसी का नाम पूछना रह गया, और उसे ठीक करने का कोई तरीक़ा नहीं बचा।
वे उन लोगों के लिए लिखते हैं जिनकी ज़िंदगी में कुछ छूट गया है, और जो उसे किसी से कह नहीं पाए। उनका मानना है कि ऐसी बातें ज़ोर से कहने की नहीं होतीं — उन्हें बस किसी को सुना देना काफ़ी होता है। इसीलिए उनकी कहानियों में लोग बहुत कम बोलते हैं, और चुप्पियाँ बहुत कुछ कहती हैं।
ग़ाज़ीपुर और नोएडा के बीच जितनी दूरी है, लगभग उतनी ही उनके दिन और उनकी रात के बीच है। यह किताब उस दूरी में लिखी गई है — ज़्यादातर उस वक़्त, जब बाक़ी शहर सो चुका होता था।
