FinTech & Trading Systems
MT4/MT5 server plugins in C++, plugin management and licensing platforms, and the .NET backends around them, designed and built by an engineer who has shipped them for a forex brokerage.
What I build
Server-side MetaTrader plugins run inside the trading server process. A defect affects order handling directly, so the work needs C++ discipline, careful testing and an understanding of how brokers actually operate. Engineers who combine that with modern backend architecture are rare.
Dealing desk behavior with configurable, broker-oriented slippage management; copy trading; alarm and monitoring plugins for broker operations.
A control plane that holds plugin configuration and licences centrally and keeps customer-side runtimes in sync through a desired-state model.
.NET services, React administration, ABP-based broker CRM work, Hangfire background jobs and SQL reporting.
BSC/BEP-20 transaction-service R&D with Domain-Driven Design, and architecture review of an existing TRON payment system.
Experience
Projects where I worked on the same kind of problem.
Independently architected and delivered a plugin management and licensing platform, connecting backend services, administrative interfaces, and customer-side runtime components.

How to start
Every engagement starts small and ends with written outputs. Not trading strategies, signals, investment advice or financial regulation compliance.
For a new product or major capability, before serious development starts: clear system boundaries and an implementation direction.
Not included Full implementation, UI design and infrastructure provisioning.
Ask about system designFor a team with a running system, often on .NET, that is unsure about its structure or where to take it next: what to improve, what to keep, and where to start.
Not included Executing the full migration or refactoring, which can follow as a separate engagement.
Ask about a reviewFor slow responses, recurring errors or failing background processing, investigated before committing to a major rewrite.
Not included Ongoing production support or 24/7 on-call.
Ask about an assessmentScope, duration and pricing are agreed after a first conversation, once the problem is clear.
FAQ
Yes. I have designed and built C++ server-side plugins for MT4 and MT5, including a dealing desk plugin with configurable slippage management, a copy trader plugin and an alarm system for broker operations.
Yes. I architected and delivered a plugin management and licensing platform from concept to V1: a .NET control plane with React administration, where customer-side runtime components converge on a centrally recorded desired state.
Yes. My broker work includes .NET backend services, an ABP-based broker CRM, Hangfire job troubleshooting and SQL reporting. I usually start with an Architecture Review or a Backend Reliability Assessment.
Yes. I work remotely and project-based, in English. Scope, timeline and terms are agreed in writing before work begins.
No. My focus is server-side plugins and broker backend systems, not trading strategies, signals or investment advice.
