Portrait of Subhadip Dutta
Subhadip Dutta SME & Solution Architect · Deloitte

Hello!

Hi, my name is Subhadip Dutta, an Oracle Cloud Solution Architect based in Bangalore, India. I architect Oracle Cloud solutions that connect Fusion, OCI and the wider cloud - and automate the boring parts with AI.

I’m a SME & Solution Architect at Deloitte, leading solution design and delivery for 3 Oracle Fusion clients as their primary SPOC. 🤖

Before that, five years inside Oracle as a techno-functional consultant: 8 Fusion go-lives and a Shining Star Award. ☁️

My core expertise is system integration, cloud architecture and intelligent automation - simplifying complexity through scalable design. 💡

I hold a Post Graduate Diploma in Data Science from the International Institute of Information Technology, Bangalore. 🎓

01

Enterprise Integration

Designing resilient integrations across Oracle Fusion, SaaS platforms and on-prem systems with OIC, REST/SOAP services and event-driven patterns.

02

Cloud & SaaS Architecture

Architecting on OCI and cloud ERP/CX landscapes - data models, security, extensions and performance tuning for enterprise-scale workloads.

03

Automation & AI

Building intelligent automation, chatbots and data science solutions with Python, LLMs and applied machine learning to remove manual effort.

04

Product Engineering

Shipping full products end to end - React and FastAPI apps, Android builds, APEX tools and bots, from first prototype to live users.

Architecture stories from the field

Client work, anonymised. Each one covers the problem, what I built, and the decisions that shaped it.

  • Consumer goods
  • Global MNC
  • OIC3 · Fusion ERP · ATP · APEX

Cross-cloud, event-driven integration hub

AP and PO data had to reach third-party platforms outside Oracle reliably, in near real time, and with a full audit trail.

  • 40integrations
  • 50,000records a day
  • 3h → 30mend-to-end latency
  • −60%errors

What I built

  • Fusion ERP business events feed OIC3 orchestrations.
  • Metadata-driven routing: rules live in ATP and are maintained through an APEX admin UI rather than hardcoded.
  • Outbound REST connects to the external platforms.
  • A central audit and error store in ATP, with an APEX operations dashboard.
  • Documents are transformed from base64 to PDF in-flow.

Key decisions

  • Event-driven over scheduled batch to cut latency.
  • Routing as data, not code, so new targets ship without redeploying integrations.
  • Governance on ATP and APEX to keep operational control inside OCI.

  • Deloitte internal initiative
  • Fusion AI Agent Studio · Microsoft Graph

Agentic AI on Fusion, bridged to Microsoft 365

A known class of Fusion failure always needed the same fix, yet it still meant a ServiceNow ticket and people chasing each other to apply it and close the issue.

  • 8resolution steps automated
  • 2clouds: Oracle and Microsoft 365
  • Humanapproval before every commit

What I built

  • An Oracle Fusion AI Agent Studio agent identifies the resolution step and calls external REST tools against Fusion and other APIs.
  • A human-approval node sends email through Microsoft Graph, authenticated with M365 / Entra ID.
  • Scheduled async workflows resume once the approver responds, and write the result back to Fusion.

Key decisions

  • Humans stay in the loop for anything that commits a transaction.
  • Async by design, so long-running approvals never hold sessions open.

Architecture governance at run-time

On a live Fusion estate, ownership across support tiers was unclear and every Oracle quarterly update carried risk.

  • 400 → 150backlog
  • 3d → 1dFusion post-clone release cycle

What I built

  • An operating model with L1.5 / L2 / L3 tiering and a RACI.
  • Environment-aware release planning around P2T refreshes, quarterly updates and close freezes.
  • Regression and evidence tooling for quarterly update certification.

Key decisions

  • Sequence changes around Oracle’s quarterly cadence, not against it.
  • Tier ownership so L3 architects aren’t pulled into L1 noise.

Domain Depth

Industries I’ve worked in

The same integration craft lands differently in every sector - different systems, different compliance shape, different definition of “urgent”.

🚗5 yrs

Automobile

The deepest run of my career - order-to-cash, dealer and supply-side integrations across a manufacturing operation that never stops.

🛒3 yrs

Consumer

High-volume, low-margin, and unforgiving about latency. Order and fulfilment flows where a slow integration is a lost sale.

🏭2 yrs

Manufacturing

Work orders, production reporting and material movement - plant-floor execution wired back into Fusion, where a stalled interface stalls the line.

🏢1 yr

Real Estate

Long-lived projects, heavy documentation, and money that moves in milestones rather than transactions.

Short but sharp. Controls, audit trails and reconciliation first - every integration has to be able to explain itself.

Queen Beth Bot · Telegram

A chess-playing bot deployed on OCI, serving moves and games straight inside Telegram.

PythonOCI

Queen Beth Bot · Telegram

Queen Beth plays a full game of chess inside a Telegram chat - you send a move, the engine replies with its own and a freshly rendered board. It runs as an always-on Python service on Oracle Cloud Infrastructure, holding game state per chat so several games can run side by side without tripping over each other.

Queen Beth Bot · Discord

PythonOCI

Queen Beth Bot · Discord

The Telegram engine repackaged for Discord, where a game belongs to a channel rather than a private chat. Slash commands drive the moves, and the same OCI-hosted Python service backs both bots - so a fix to the engine lands in each of them at once.

I have known Subhadip for almost seven years, and he is among the most qualified people in Oracle Cloud ERP and CRM. It is amazing how he can handle different fields, from one project to another, with much ease. There is no other person who can be compared to him when it comes to solution and integration development; his output has always remained at the top level.
