Fintech backend systems and observability dashboards

Senior .NET Backend Engineer for fintech, trading, and distributed systems

Backend systems that stay fast when the business gets complex.

I design, modernize, and stabilize business-critical software across fintech, trading, SaaS, insurance, automotive, and retail. My strongest zone is where C#/.NET, SQL, messaging, observability, and production ownership meet.

Positioning

I turn fragile, expensive backend flows into measurable engineering leverage.

The pattern across my work is consistent: understand the business process, expose the technical bottleneck, simplify the service contract, optimize the data path, add observability, and leave the team with a system they can operate with confidence.

What I bring

Senior backend range, with production scars.

FinTech and trading backend

Production services for trading environments, MT4 data retrieval, event synchronization, WebSockets, Kafka, Redis, and low-latency workflows.

Distributed systems design

Microservices, event-driven architecture, gRPC, API contracts, fault-tolerance testing, backup switching, and resilient service integration.

Legacy modernization

Extracting business logic from legacy platforms, moving services to modern .NET stacks, Docker, Kubernetes, CI/CD, and GitOps deployment flows.

Performance and SQL depth

Execution plans, stored procedures, distributed queries, backend bottleneck analysis, data retrieval optimization, and measurable speed gains.

Production troubleshooting

Deep debugging, observability, incident support, code reviews, test coverage, logging flows, and root-cause analysis in complex systems.

Technical leadership

Team leading, mentoring, task decomposition, engineering estimates, quality control, documentation, and cross-functional delivery.

Experience

Career evidence, not buzzwords.
