Backend Rust Developers

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

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

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

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

Designed and implemented distributed systems for high-availability services using Rust and Python. Led teams in developing blockchain-based applications with a focus on smart contract security.

• Optimized SQL databases for performance and scalability
• Authored technical documentation for complex system architectures
• Contributed to open-source distributed ledger projects

Designs and operates distributed services and data infrastructure in Go and Rust, including modernization of legacy advertising platforms into AWS and Kubernetes microservices. Recent systems work also covers event processing, workflow engines, and integrating agentic LLM capabilities into production applications.

• Built analytics pipelines with Apache Arrow Flight and Parquet
• Implemented messaging flows using NATS and RabbitMQ
• Used AWS Kinesis, Firehose, Glue, and Athena
• Developed local-model workflows with vLLM and LangGraph

Built high-throughput Go backend services benchmarked at 8,420 requests per second with 11.45 ms p95 latency and zero errors. Designed Kubernetes infrastructure with custom HPA/KEDA autoscaling, gRPC services, WireGuard networking, and OpenTelemetry tracing, reducing cluster expenditure by 35%.

• Multi-provider LLM routing gateway
• MCP server and Claude Code integrations
• Multi-tenant RBAC with OAuth2/OIDC
• PostgreSQL indexing and PgBouncer tuning

Develops asynchronous concurrent Rust services on Tokio for algorithmic digital-asset trading across more than 140 centralized and decentralized exchanges.
