Hire
Fintech Rust Developers

Leads backend architecture for a production trading platform handling real user funds, with single-writer state, idempotent workflows, atomic settlement, and fail-closed reliability controls. Builds low-latency Rust services using Tokio and Axum, including real-time gRPC and WebSocket data pipelines.

• Normalized multi-source market data with freshness handling
• Designed bounded-channel backpressure and workload-isolated job queues
• Operated PostgreSQL, Redis, ClickHouse, Kafka, and Flink systems
• Developed Solana programs for on-chain transaction workflows

Architected electronic trading systems for FX and digital assets, including exchange connectivity, FPGA market-data adapters, trade capture, portfolio management, and risk controls. Also developed online machine-learning systems under extreme latency constraints and transactional platforms requiring extensive auditability and correctness.

• Embedded Rust for performance-sensitive devices
• OTC pricing and streaming infrastructure
• PostgreSQL trade-booking database design
• Mechanical-sympathy low-latency architecture

Designs Rust services for latency-sensitive trading, signal generation, asynchronous networking, and Kafka- or RPC-driven distributed workflows. Security work covers wallet hardening, MPC/DKG signing, HSM and TEE integration, while product delivery spans backend, web, and mobile clients.

• WebSocket market-data services
• KDB+ financial data workflows
• AI-agent prompt security
• Solidity smart-contract integration

Builds Rust financial infrastructure for blockchain networks, including a WebAssembly execution engine, transaction processing, staking and rewards logic, and developer SDKs. Has designed production systems for exchanges, crypto-fiat payments, big-data pipelines, and cloud platforms using Kafka, BigQuery, Kubernetes, Knative, and Terraform.

• EVM and L2 execution components
• Reth node infrastructure operations
• Centralized exchange backend integrations
• Cloud SRE architecture

Builds backend platforms around PHP 8+, Symfony, Laravel, and NestJS, using domain-driven, hexagonal, and event-driven architectures for REST APIs and microservices. Has implemented distributed integrations across AWS messaging services, Kubernetes deployments, relational and document databases, and regulated authentication flows.

• Designed OpenAPI contracts for service integrations
• Implemented OAuth2, OIDC, JWT, and Keycloak security
• Applied TDD with PHPUnit, Jest, and SonarQube
• Built event workflows with AWS SNS and SQS

Designed and delivered a multi-tenant SaaS platform end to end, covering architecture, backend services, testing, cloud deployment, and production operations. Builds event-driven microservices and state-machine workflows for banking, payments, supply-chain, and enterprise integration systems, with measured 45% throughput improvement and 30% lower API latency.

• Rust and Go asynchronous service development
• REST API and enterprise integration architecture
• Database refactoring for high-volume workloads
• Cloud-native deployment and production hyper-care

Works across kernel-space networking, low-latency trading infrastructure, and on-chain financial protocols, including Linux drivers, order books, and automated market makers. Builds Rust systems ranging from no_std components and C-interoperable modules to high-load Axum services.

• Implemented Solana governance using program-derived addresses
• Developed token-based voting smart contracts
• Built Rust backends with Rocket and Axum
• Integrated eBPF traffic-control instrumentation

Develops Rust-based partner integrations for fintech and e-commerce platforms using gRPC and Protobuf, covering API design through AWS deployment and production operations. Works on payment, budgeting, and supplier-connectivity workflows requiring idempotent retries, observability, and reliable transaction processing.

• Kafka-backed distributed data pipelines
• Neo4j relationship-data modeling
• Kubernetes deployment automation
• Canary releases through Jenkins

Built distributed microservices, low-latency quantitative trading engines, and high-concurrency communications platforms serving hundreds of thousands of users. Current systems work includes Rust market-making, deterministic AI agent control layers, multimodal document pipelines, and semantic enterprise search.

• On-chain quoting, hedging, and risk-limit enforcement
• MCP infrastructure for agentic workflow orchestration
• Neural raster-to-blueprint vision processing
• Sub-60-second commit-to-production delivery pipelines

Built a Rust crypto payment processor with invoice lifecycles, liquidity balancing, exchange-rate aggregation, and exact fixed-point monetary arithmetic. Also developed decentralized Bitcoin-wallet infrastructure covering blockchain indexing, low-latency data services, binary protocols, and Haskell/Rust concurrency.

• Rocket and Tokio services
• PostgreSQL payment persistence
• 3D game-engine architecture
• Embedded battery monitoring

Designed low-latency messaging systems using Kafka and Aeron in Rust. Developed high-performance data processing pipelines integrated with PostgreSQL for real-time analytics.

• Designed low-latency systems with Kafka
• Built data pipelines in Rust
• Integrated PostgreSQL for analytics

Engineered a scalable event-driven system in Rust for IoT device management. Developed a cross-platform communication protocol using Go and C++.

• Built a TypeScript-based dashboard for real-time monitoring
• Optimized Python scripts for data aggregation
• Utilized Node.js to enhance backend efficiency

Built cloud data platforms and migration architectures, including an on-premises SQL Server warehouse transition to Azure Synapse and SAP S/4 extraction pipelines. Works across infrastructure automation, observability, performance engineering, security compliance, and cost optimization for data-intensive systems.

• Terraform-based Azure infrastructure provisioning
• Polars and Dremio analytical data processing
• Splunk observability for production platforms
• SAP extraction tooling compliant with SAP Note 3255746

Designed privacy-focused financial systems spanning self-custody blockchain infrastructure, DeFi, and enterprise platforms. Applies fully homomorphic encryption, zero-knowledge proofs, multiparty computation, and distributed key generation to production financial products while working across protocol and cloud-service layers.

• Solana and Sui ecosystem development
