Professional Portfolio Web Applications and Software I made for others

Summary

This management software helps Forex Brokers deal with all their day-to-day tasks, and provides a front-end for their customers to manage their accounts.

Customers fill in all their information, upload documents to verify their identity and address, deposit money into their trading accounts automatically using one of several payment options, request withdrawals, transfer money from one account to another, etc.

The system creates and maintains trading accounts automatically, deposits and withdraws funds from them when requested, monitors trading, pays commissions to affiliates, bills customers for services when necessary. All automated to save time for the broker's staff.

It has a huge amount of features, too many to list here; read about the most important below:

Highlights

• Reliable: Has managed money movements for over $100 million USD to date, for more than 10 thousand customers, without ever misplacing a penny. Also has many internal consistency checks, so when money pops up in an account unexpectedly, or pretty much anything goes wrong, it immediately warns the admins. Finally, it keeps an audit trail of everything that happens, for later verification.
• Automated: Automatically creates trading accounts, deposits, withdrawals, commissions, VPS server instances, etc. This saves admins enormous amounts of time compared to other brokers who normally do these manually.
• Multi-platform: Supports several different trading platforms. More importantly, the platform-specific details are subclassed and abstracted away from the core logic, so that adding new platforms to the system is a matter of days.
• Highly Configurable, Multi-lingual and Whitelabel-able: Everything that the user sees, from content to the types of accounts offered, email templates, plus a considerable amount of system behavior is configurable. In fact, right now the software is working for 2 completely different brokers with the same exact codebase, and is currently being offered to other brokers without modification to the code.
• Affiliates System: Has a very sophisticated affiliates system, allowing the broker to calculate and pay commissions in several different ways, and allowing affiliates to offer different commercial conditions to their customers.
• Automatic Billing: Customers get billed monthly for different services that the broker offers. This billing is fully automated, based on usage of these services.
• Salesforce Integration: Tight integration with the Salesforce API, to keep sales and support people up to date on everything that happens with a customer.
• Payment Processors: Integrates with several different payment processors giving customers more options to fund their accounts.
• Performance: I had a 2-year hiatus in this project, during which another company maintained it and added features. When I went back, one of my main jobs was getting performance back to an acceptable level. This was done mainly by improving access patterns to both database and trading servers, doing few large queries instead of thousands of small ones. On average, this resulted in a 40x improvement in speed, and a 250x reduction in the number of queries, and batch processes going down from over 10 hours to a few minutes per run. This improvement was vital in the case of trading servers which were getting swamped with queries to the point that their main functionality was being impaired.
