I will migrate your python node backend script or app to rust
Ahsan
About this gig
Your system already works. I help you move the slow, risky, or memory-heavy parts to Rust without breaking what is already working.
This gig is for founders and teams with an existing Python, Node.js, JavaScript, TypeScript, backend, API, worker, bot, CLI tool, data pipeline, or automation system that now needs better speed, memory safety, and reliability.
I can migrate:
- Slow Python scripts to Rust
- Node.js APIs or workers to Rust
- Backend modules and microservices
- Bots, queues, schedulers, and event workers
- Data processing and file processing tools
- CLI tools and internal automation
- WebSocket or high-concurrency services
- Performance-critical business logic
I do not push a full rewrite unless it is actually needed. The usual best move is to identify the bottleneck, rewrite that part in Rust, keep the same behavior, add tests, document how it runs, and make it easy to integrate with your current system.
You get practical Rust migration, not experimental code.
Message me before ordering with your repo, current stack, the slow or unstable part, sample inputs/outputs if available, and the result you want.

I’m a Lead Software Engineer with 4+ years of deep technical experience building and optimizing production-grade AI systems that perform at scale. I don’t just stitch APIs together, I architect, optimize, and deploy high-performance solutions. Core Focus Areas: Complete RAG systems, autonomous agents, automation, voice agents, and chatbots and fine-tuned LLM deployments. Transform messy prototypes and vibe code into clean, scalable applications with CI/CD, monitoring, and AWS/GCP deployments. When Python hits its ceiling I migrate to high-performance Rust (pyO3, Maturin) for 10-100x speedups.

FAQ
Do I need to migrate my whole app to Rust?
Usually no. Most products should not be fully rewritten at once. A better approach is to migrate the bottleneck first: one worker, API route, script, bot, module, or service. That gives you Rust benefits with less risk.
How do you avoid breaking my existing system?
I first understand the current behavior, inputs, outputs, edge cases, and integration points. Then I rewrite the scoped part in Rust and keep the same expected behavior. If needed, I add tests or comparison checks against the old version.
Can you show performance improvement?
Yes, if you provide a sample workload, input data, or current benchmark. I can compare the old implementation with the Rust version and share practical before/after results. I do not promise fake speed numbers before seeing the code.
Can the Rust code work with my current Python or Node.js app?
Yes. The Rust part can be delivered as a separate service, CLI tool, worker, API, Dockerized service, or module depending on your system. The goal is to improve the critical part without forcing you to rebuild everything.
What do you need from me?
I need the repo, setup instructions, current tech stack, the exact part you want migrated, the problem you are seeing, sample inputs/outputs, and your target environment. Do not send passwords or secret keys in the order requirements.
