Rust Development

WAYF is a Rust Development Agency:
When Performance Isn't Optional.

Performance without compromise. Memory safety without garbage collection. For the parts of your system where those properties matter.

Rust isn't our primary language—React and TypeScript are. But some problems require what Rust offers: predictable performance, memory safety enforced at compile time, and the ability to run close to the metal. When we reach for Rust, it's because the problem demands it, not because we wanted to use it.

What We Build

Performance-critical services. Backend components where latency matters—real-time systems, high-throughput APIs, services handling thousands of concurrent connections. When Node.js or Python can't meet your performance requirements, Rust often can.

CLI tools and developer infrastructure. Build systems, code generators, development utilities. The startup time and resource efficiency of Rust make it excellent for tools that run frequently.

WebAssembly modules. Compute-intensive logic that needs to run in the browser at near-native speed. Image processing, cryptography, data transformation—tasks where JavaScript's performance isn't sufficient.

Blockchain and Web3 infrastructure. Smart contract tooling, indexers, node implementations. The blockchain ecosystem has embraced Rust for its safety guarantees and performance characteristics.

Systems integrations. Components that need to interface with operating systems, hardware, or legacy systems. When you need FFI, low-level networking, or direct memory control, Rust provides it safely.

What we build less of: everything else. Rust has a learning curve and a development velocity cost. For CRUD applications, admin dashboards, or services where developer productivity matters more than raw performance—use something else. We'll tell you when Rust is solving a problem you don't have.

Why Us

Honest Assessment First

Most projects don't need Rust. Web applications, APIs, mobile apps—TypeScript and the broader JavaScript ecosystem handle these well and with faster development cycles. We use Rust when there's a genuine technical reason: performance requirements, memory constraints, safety-critical systems. If your project would be better served by Node.js, we'll say so.

Integrated with Our Stack

Our Rust work typically complements our JavaScript/TypeScript applications—a high-performance service that a React frontend consumes, a WebAssembly module embedded in a web application, a CLI tool that supports a larger development workflow. We understand how Rust components fit into broader systems.

They've built Node.js services that scaled and inherited ones that didn't. They know what Node.js handles well—APIs, real-time apps, lots of simultaneous connections—and where other tools work better. They won't recommend Node.js for problems it wasn't designed to solve.

Seniority and Systems Thinking

Engineers who write good Rust understand computer science fundamentals—memory models, concurrency primitives, systems architecture. Our team brings that depth. They've shipped Rust in production and know the tradeoffs: longer compile times, steeper onboarding, smaller talent pool. They recommend Rust only when the benefits outweigh these costs.

Seniority and Systems Thinking

Not every backend needs microservices. Not every API needs GraphQL. We build what your application actually requires, not what's fashionable. Sometimes that's a simple Express server. Sometimes it's a more sophisticated architecture. We'll tell you which and why.

Range of Application

We've used Rust for startup prototypes where performance was a differentiator and for enterprise systems where reliability was non-negotiable. Different contexts require different approaches to error handling, deployment, and maintenance. We calibrate accordingly.

How We Work

Rust projects often emerge from larger engagements. A web application with a performance bottleneck. A system that needs a high-throughput component. A product that requires WebAssembly for browser-based computation. We identify where Rust adds value and scope the work accordingly.

When a project is primarily Rust—a CLI tool, a systems service, infrastructure software—we apply the same process we use everywhere: two-week sprints, working software at each checkpoint, decisions documented, direct communication throughout.

What makes Rust projects different: the feedback loop is slower. Compilation takes longer. The type system is stricter. Problems that would manifest as runtime errors in other languages become compile-time errors in Rust—which is the point, but it changes development rhythm. We account for this in planning.

What stays constant: clear communication about progress, honest assessment of timeline, and feedback that serves your interests even when it's uncomfortable. Some Rust projects take longer than clients expect. We'd rather set realistic expectations than promise speed we can't deliver.

Technical Approach

Memory Safety as Architecture

Rust's ownership model isn't just a language feature—it's a design discipline. We structure code to make ownership clear, avoid unnecessary allocations, and leverage the compiler's guarantees. When we need shared state, we choose the right primitive: Arc, Mutex, channels. Not by default, but deliberately.

Error Handling Done Properly

Result types, not exceptions. Errors as values that must be handled. We design error types that provide meaningful context and propagate gracefully. panic! is for programmer errors, not runtime conditions.

Async Where it Matters

Tokio for async I/O when we need concurrent connections. Synchronous code when we don't. Async Rust adds complexity; we use it when the performance benefit justifies that complexity, not because it's fashionable.

Testing That Builds Confidence

Unit tests for core logic. Integration tests for system boundaries. Property-based testing where invariants matter. Rust's type system catches many errors, but it doesn't catch logic bugs—tests do.

Dependencies Evaluated Carefully

The Rust ecosystem has excellent crates and unmaintained ones. We evaluate dependencies for quality, maintenance status, and security posture. Fewer dependencies mean fewer supply chain risks and faster compile times.

Performance Measured, Not Assumed

Rust enables performance but doesn't guarantee it. We profile, benchmark, and optimize based on data. Sometimes the fastest code is also the most idiomatic; sometimes optimization requires different approaches. We measure to know which.

Cross-Compilation and Deployment

Building for multiple platforms, containerization, CI/CD integration. Rust's compilation model is different from interpreted languages; we handle the infrastructure to make deployment smooth.

What We See Go Wrong

The most common mistake: choosing Rust for the wrong reasons. "Rust is fast" doesn't mean every project needs it. If your bottleneck is database queries, network latency, or algorithmic complexity, rewriting in Rust won't help. We've seen teams spend months porting services to Rust only to find the performance gains didn't matter for their actual users.

We also see teams underestimate the ecosystem gap. Rust's library ecosystem is excellent for certain domains and sparse for others. Authentication libraries, ORM-style database access, web frameworks—these exist but often require more configuration than their JavaScript equivalents. Teams expecting the same convenience as npm sometimes struggle.

Another pattern: treating Rust like other languages. Fighting the borrow checker instead of designing with it. Reaching for unsafe code without understanding the alternatives. Writing Java-style object-oriented code when Rust's idioms point elsewhere. Rust rewards learning its patterns; teams that resist them have a harder time.

We're not here to judge prior decisions. Sometimes Rust was the right choice but implementation struggled. Sometimes it was the wrong choice and the path forward is rewriting in something else. We assess the situation honestly and help figure out what makes sense now.

Who We Work Well With

Teams who have a specific performance or safety problem that Rust solves. Not "we want to use Rust" but "we need sub-millisecond latency" or "we need memory safety guarantees for this security-critical component."

Also: teams building WebAssembly for the browser, CLI tools for developers, or blockchain infrastructure where Rust is the established choice.

What both share: realistic expectations about Rust's tradeoffs—longer development time, smaller talent pool, steeper learning curve—and a genuine technical reason that justifies them.

Who We're Not For

If you want Rust because it's interesting or because it's perceived as modern—without a concrete technical requirement—we'll have an honest conversation about whether that's the best use of your resources.

If you're comparing agencies on rate and expecting Rust development at JavaScript prices, the math won't work. Rust engineers are scarcer, the development cycle is slower, and the work requires deeper expertise. Quality Rust development costs more.

If you need a team entirely focused on Rust, with deep expertise across its full ecosystem, you may want a Rust-specialized shop. We use Rust as one tool among several, integrated with our broader TypeScript and React work. That integration is valuable for many projects—but not all.
