Systems & Architecture — An Overview
Enterprise Investment & Wealth Management platforms are composed of a set of core systems, data platforms, and external integrations. For a detailed, interactive breakdown of the core systems and the step-by-step business flows, see the Core Systems and Business Flows sections below.
The remainder of this section presents a high-level architecture diagram to visualise how channels, API gateway, backend services, data layers and external partners fit together. Use the detailed sections below for concrete system names, API examples, and the full end-to-end walkthroughs.
Technology Architecture — How Investment & Wealth Management Platforms Are Built
Modern Investment & Wealth Managementplatforms follow a layered microservices architecture. The diagram below shows how a typical enterprise system in this domain is structured — from the client layer through the API gateway, backend services, data stores, and external integrations. This is the kind of architecture you'll encounter on real projects, whether you're building greenfield systems or modernising legacy platforms.

Business Flows
Key Business Flows Every Developer Should Know.Business flows are where domain knowledge directly impacts code quality. Each flow represents a real business process that your code must correctly implement — including all the edge cases, failure modes, and regulatory requirements that aren't obvious from the happy path.
The detailed step-by-step breakdown of each flow — including the exact API calls, data entities, system handoffs, and failure handling — is covered below. Study these carefully. The difference between a developer who “knows the code” and one who “knows the domain” is exactly this: the domain-knowledgeable developer reads a flow and immediately spots the missing error handling, the missing audit log, the missing regulatory check.
Technology Stack
Real Industry Technology Stack — What Investment & Wealth Management Teams Actually Use. Every technology choice in Investment & Wealth Managementis driven by specific requirements — reliability, compliance, performance, or integration capabilities. Here's what you'll encounter on real projects and, more importantly, why these technologies were chosen.
The pattern across Investment & Wealth Management is consistent: battle-tested backend frameworks for business logic, relational databases for transactional correctness, message brokers for event-driven workflows, and cloud platforms for infrastructure. Modern Investment & Wealth Managementplatforms increasingly adopt containerisation (Docker, Kubernetes), CI/CD pipelines, and observability tools — the same DevOps practices you'd find at any modern tech company, just with stricter compliance requirements.

Interview Questions
Q1.What is the difference between a PMS and an OMS in investment management?
PMS (Portfolio Management System) tracks what you own — holdings, performance, risk, P&L. OMS (Order Management System) handles what you're doing — creating, routing, executing, and allocating trades. They integrate tightly: PMS identifies need to rebalance, OMS executes those orders. After trade settles, OMS sends confirmation back to PMS to update positions.
Q2.Explain T+1 settlement and its technical implications.
T+1 means trades settle 1 business day after trade date (India moved to T+1 in Jan 2023, one of first globally). Technical implications: 1) Tight SLA — all matching, confirmation, and position updates must complete same day, 2) Straight-through processing is critical — no manual intervention, 3) Fund managers need same-day NAV and margin availability, 4) Requires real-time integration between broker, NSCCL/ICCL clearing, and CDSL/NSDL depository.
Q3.How does NAV calculation work for mutual funds?
NAV = (Total Assets - Total Liabilities) / Number of Units Outstanding. Calculated daily after market close: 1) Mark-to-market all equity/debt holdings at closing prices, 2) Add accrued income (dividends, interest), 3) Subtract expenses (expense ratio accrual), 4) Divide by units outstanding. Published by AMFI by 9 PM. Investors who transact before cut-off (3 PM equity, 1 PM debt) get that day's NAV.
Q4.What is the FIX protocol and why is it important?
FIX (Financial Information eXchange) is an industry-standard messaging protocol for electronic trading. Key message types: New Order Single (place order), Execution Report (fill confirmation), Order Cancel Request, Mass Quote (for market makers). Important because it's universally accepted by exchanges and brokers globally — enables interoperability. India's NSE and BSE support FIX API for direct market access.
Q5.Explain how SIP works technically end-to-end.
1) Investor registers SIP → stored in platform DB and registered with AMC via BSE StAR MF / CAMS. 2) eMandate/UPI AutoPay registered with bank for auto-debit. 3) On SIP date: NACH/AutoPay debits investor account. 4) Platform creates purchase transaction. 5) Sent to AMC (directly or via RTA). 6) AMC allots units at that day's NAV after 3 PM cut-off. 7) Units credited to investor folio. 8) Confirmation sent. SIP can be modified or stopped by cancelling mandate.
