Varun G.

I build high-performance backend systems, APIs, and applications using Rust, Golang, and WebAssembly. My focus is on writing fast, reliable, and memory-efficient software that can handle complex workloads and scale without unnecessary infrastructure costs. With 9+ years of software development experience, I work across systems programming, backend engineering, real-time applications, and AI-powered solutions. What I Can Help You Build: Rust Development - High-performance backend services and APIs - Async programming with Tokio and concurrent systems - Memory-safe, efficient applications - WebSocket servers and real-time communication - Performance optimization and Rust integrations Golang Backend Development - Scalable REST APIs and microservices - Concurrent applications using Goroutines and Channels - Backend architecture and third-party integrations - PostgreSQL, Redis, Docker and cloud deployment - Real-time systems and background workers WebAssembly (WASM) - Rust to WebAssembly development - Browser-based high-performance modules - JavaScript/TypeScript and WASM integrations - Existing application performance improvements - Cross-platform modules and reusable components AI & Python Engineering - AI Agents, LLM integrations and RAG pipelines - Python/FastAPI backend development - AI workflow automation and MCP integrations - Real-time AI applications and external API integrations Where I Fit Best: I work best on projects that need more than basic CRUD development, particularly when performance, reliability, concurrency, or complex backend integrations are involved. Whether you're building a new backend, migrating performance-critical components to Rust, developing Go microservices, or integrating WebAssembly into an existing application, I can help with architecture, implementation, testing, and deployment. I value clean code, practical solutions, clear communication, and long-term maintainability.
