Vicky Paswan — Backend Engineer

I am a Senior Backend Engineer & Tech Lead specializing in Rust-based backend systems, distributed architectures, and AI agent platforms. With 5+ years of experience, I build high-performance, cloud-native systems that power ERP platforms, SaaS products, and AI-driven automation at scale. My work focuses on correctness under concurrency, predictable latency, and cost-efficient infrastructure, not just feature delivery. As a Rust Backend Developer, I design and operate systems using Rust (Axum, Tokio), optimized PostgreSQL, and stateless architectures that scale reliably under real-world traffic. As an AI Agent Developer, I build agentic AI backends using LangGraph and LangChain, where multiple agents collaborate through deterministic DAG-based reasoning pipelines to deliver explainable, reliable outcomes, not prompt-based guesswork. Core Expertise • Backend & Distributed Systems: Rust, Axum, Tokio, Node.js, NestJS • AI Agents & LLM Systems: LangGraph, LangChain, Gemini SDK, OpenAI SDK • Databases & Data Systems: PostgreSQL (performance tuning, partitioning), Redis, MongoDB • Cloud & DevOps: AWS, Docker, Kubernetes, CI/CD, GitHub Actions • Enterprise Platforms: ERP backends, Fintech systems, high-scale E-commerce Impact Highlights • Led migrations from Node.js to Rust, achieving ~60% infrastructure cost reduction and 3–10× performance gains • Partnered with 80+ businesses to deliver scalable backend and AI systems • Built ERP-grade platforms handling inventory, orders, logistics, and audits • Designed and deployed autonomous AI agents for analytics, decision support, and workflow automation My mission is to build backend systems and AI platforms that scale predictably, fail safely, and remain maintainable for years, while helping organizations adopt next-generation Rust and AI architectures with confidence.
