Backend Rust Developers

Designed Rust backend architectures for regulated workflows, including KYC review orchestration, audit trails, identity-provider abstraction, and signed URL security. Built distributed integrations spanning PostgreSQL, Redis, Stripe billing, blockchain notarization, and MCP-based tooling.

• Bayesian reviewer-assistance model
• SeaORM migration with feature continuity
• Subscription and usage-based billing
• Casbin authorization policies

Designed and migrated a carrier-integration platform serving millions of daily requests with availability above 99.99% and no customer-facing migration downtime. Implemented Rust/Axum accounting integration plus event-driven workflow services for shipment placement, invoicing, retention, and financial synchronization.

• Attribute-based authorization with CASL
• BullMQ event-processing workflows
• Kubernetes and Terraform platform operations
• GCP and AWS cloud migrations

Builds Rust services and data pipelines for viewership analytics, ingesting and processing nearly 100 GB of audience data daily from multiple providers. Maintains systems backed by more than 1 PB of historical records while supporting performance, availability, and reliability requirements.

• Standardized CRM extensions across Windows, Linux, and Android
• Developed Kotlin, Java, and C# business applications
• Worked across SQL-backed service and reporting layers

Built low-latency Solana and DeFi trading infrastructure in asynchronous Rust and Go, including multi-venue arbitrage, Drift automation, and Anchor-based on-chain programs. Implemented Yellowstone gRPC market-data streaming, Jupiter routing, Jito bundle submission, and transaction simulation for automated execution reliability.

• Bridged Rust services with Python using PyO3
• Built asynchronous backend services with Tokio and Axum
• Integrated PostgreSQL, MySQL, MongoDB, and Oracle databases
• Automated containerized delivery through Docker and GitHub Actions

Develops crash-resilient Rust and Python services around asynchronous event streams, binary protocols, WAL-backed storage, and POSIX concurrency primitives. Combines API security engineering with property-based testing, constant-time cryptography, and distributed resilience patterns.

• BOLA and IDOR authorization boundary audits
• PostgreSQL WAL and SQLite FTS5 systems
• Circuit breakers and concurrency bulkheads
• AST-based query gating for secure APIs

Built backend platforms for SaaS, AI/ML, CRM, mobility, and data-intensive products, including services developed from an empty repository to investor-demo readiness in two months. Delivered asynchronous processing and distributed-service architectures using PostgreSQL, message brokers, WebSockets, vector search, and cloud infrastructure.

• Qdrant-backed retrieval systems
• NATS JetStream event processing
• Terraform-managed AWS infrastructure
• RabbitMQ workload orchestration

Designed cloud-native microservices serving more than 10 million daily active users across advertising technology, financial technology, and ERP systems. Led legacy migrations and operated event-driven services on AWS and Kubernetes using asynchronous processing and distributed data infrastructure.

• Kafka streaming and Apache Druid analytics
• DynamoDB and Athena data platforms
• Go and C#/.NET service development
• Terraform infrastructure automation

Engineered a decentralized finance protocol on Ethereum, focusing on security and gas optimization. Developed smart contract frameworks for Solana, enabling efficient cross-chain transactions. Contributed to the core development of a blockchain consensus mechanism, enhancing throughput and latency.

• Created a custom Rust-based library for cryptographic operations
• Integrated TypeScript tooling for blockchain application interfaces
• Designed a Solidity-based tokenomics model for a new crypto asset
• Built a cross-platform wallet application with advanced security features

Engineered distributed systems in Go and Rust for payment processing, Web3 infrastructure, smart contracts, and cross-chain services, including ecosystems exceeding 200 microservices. Maintained tier-one transaction workloads on Kubernetes with operational practices centered on failure behavior, deployment safety, and observability.

• Open-source Go multi-agent orchestrator
• Cross-chain backend integration
• Prometheus and Grafana platform monitoring
• Docker-based production deployments

Architects real-time connected-device platforms and distributed compute systems in Go and Rust. An IoT backend handles approximately 350,000 concurrent devices and peaks near 300,000 messages per second, while a separate Rust platform combines Tokio, NATS, Raft, PostgreSQL, and WebAssembly.

• Designed versioned binary device protocols
• Implemented multi-level sharding for hot paths
• Built custom columnar time-series storage
• Performed zero-downtime PostgreSQL migrations

Provided expert consulting on Rust-based system architectures for financial services. Developed high-performance data processing pipelines for real-time analytics. Integrated cross-platform solutions with C# and Python for enterprise clients.

• Consulted on Rust architectures
• Developed real-time data pipelines
• Integrated cross-platform solutions

Builds backend systems, desktop software, API integrations, and AI automation workflows across Rust, Python, and native C++. Recent work includes payment reconciliation, operational platforms, distributed services, and document-context retrieval pipelines.

• Maintains PostgreSQL, MySQL, DynamoDB, and SQLite systems
• Deploys infrastructure with Kubernetes and Terraform
• Implements REST APIs and webhook integrations
• Builds LLM agents with n8n and Make

Developed asynchronous Rust and Tokio services for Solana MEV trading, including arbitrage, liquidation, Jito submission, and bundle lifecycle tracking. Also isolated transaction signing and key-generation workflows behind a dedicated Rust API for custody-sensitive operations.

• Built matching and pre-trade risk components
• Used ClickHouse for market-data workloads
• Implemented Kafka and NATS messaging
• Profiled p95 and p99 latency
