Research & external contracts
Deep engineering, from Africa to the world.
Our teams lead research in Rust, the Linux kernel, networking, AI and automation, and systems engineering. It's what keeps xlambda fast, and it's open for your hardest problems through external contracts.
Rust
Memory-safe, fearless-concurrency systems: our default for new performance-critical services and the language of our quant research engine.
- Async runtimes and networking
- Low-latency engines
- FFI with C/C++ pipelines
- Embedded and WASM targets
Linux kernel
Understanding the machine all the way down: tuning, tracing and extending Linux for the workloads we run.
- eBPF tracing and observability
- Scheduler and I/O tuning
- Kernel modules and drivers
- Container isolation
Networking
Moving bytes efficiently over imperfect African networks, from CDNs and streaming protocols to edge routing.
- SRT, WebRTC and HLS delivery
- Edge and CDN design
- Low-bandwidth protocols
- Traffic engineering
AI and automation
Applied AI that works with local data and local languages, from retrieval systems to autonomous agents.
- Retrieval-augmented generation
- Agents and tool use
- Swahili and multilingual NLP
- Evaluation and safety
Systems engineering
Distributed systems, storage and media pipelines that stay fast and correct under real load.
- Distributed data systems
- Media processing in C++
- Queues and back-pressure
- Reliability engineering
Research in production
C++ media workers, Go control services, SRT and WebRTC streaming and a Rust trading engine: our research ships in the products 100,000+ people use.

Open for external contracts.
For companies, governments, universities and NGOs, in Africa and worldwide.
Fixed-scope contracts
A defined deliverable (a driver, a service, a migration, a performance fix) at a fixed price and date.
Embedded engineers
Our engineers join your team for a quarter or more, working in your repos and rituals.
Research partnerships
Joint research with universities and companies, with publishable results where you want them.
Audits and reviews
Performance, reliability and security reviews of existing systems, with a prioritised fix list.
