Engineer Ultra-Low Latency Cryptocurrency Market-Making Core on AWS

@AwaisChaudhry

Hello, I understand you want an ultra-low latency crypto market-making core on AWS using Aeron and SBE, with a single-server, multi-process IPC design to bypass the network stack, and tuned for c5n with Kernel Bypass and CPU Pinning. My approach is three milestones: Milestone 1 creates a solid foundation on Amazon Linux 2023 with a custom boot script to isolate CPUs, disable C-States, and set up HugePages, plus an optimized Aeron Media Driver config. Milestone 2 defines five core SBE schemas with explicit 64-byte padding and includes a C++ Ping-Pong latency harness to prove sub-5 microsecond IPC round-trips. Milestone 3 builds a minimal single-threaded, lock-free C++17/20 core pinned to a core, with a busy-spinning duty cycle, reading from an Aeron Subscription and writing to a Publication via putOrdered, ensuring zero allocations in the main loop. I’ll provide tests, baseline metrics, and clear acceptance criteria. Do you have a preferred AWS region and any VPC/network constraints for low-latency IPC?\n\nIs production target strictly AWS c5n instances, or open to other SKUs if latency is improved?\n\nDo you require a particular Aeron version or SBE schema version constraints?\n\nWill you provide hardware profiles, or should I generate from the target instance type (c5n)?\n\nAre you planning to run on Amazon Linux 2023 for all milestones, or should we support Ubuntu for dev and Amazon Linux for prod?\n\nWhat is your acceptance criterion for Milestone 2 Ping-Pong latency (p99

Hi,\n\nI’m excited about the opportunity to engineer an ultra-low latency cryptocurrency market-making core on AWS, fully integrating Aeron and SBE to push the boundaries of performance. With substantial experience in high-frequency trading and advanced networking architectures, I am confident in achieving your target of <50 microseconds tick-to-trade latency.\n\nMy approach would be to implement a robust single-server, multi-process architecture where internal messages use Shared Memory, enhancing communication efficiency. I’ll ensure the optimizations are compliant with AWS c5n instances and further reduce latency through precise Kernel Bypass and CPU Pinning techniques. Moreover, I am well-versed in crafting custom UserData Boot Scripts and have previously implemented SBE XML Schemas that comply with strict performance requirements.\n\nI propose completing the first two milestones within 2 weeks, followed by the core development in the subsequent phases.

@shanec35

I have deep experience building ultra-low-latency trading infrastructure in C++ using Aeron, SBE and careful kernel/CPU tuning on AWS. I’ll deliver the tuned Amazon Linux 2023 UserData script, a tuned Aeron media-driver configuration, SBE XML schemas (5 message types) aligned to 64-byte cache lines, and a local IPC ping-pong harness proving microsecond round-trip latency. I’ll follow with a lock-free, pin-to-core C++17/20 event-loop skeleton that uses Aeron Publications/Subscriptions with putOrdered semantics and avoids allocations on the hot path. I’ll test on c5n-like hardware profiles, document kernel-bypass, hugepages, C-state and CPU isolation changes, and deliver reproducible instructions to reproduce benchmarks. I work to strict performance goals, provide clear benchmark evidence, and hand over commented code + configs for each milestone. I can start your project right now.

*Hello!* With 15+ years experience in software development I'm excited to help you build an ultra-low latency cryptocurrency market-making core on AWS using Aeron and SBE. *Project Understanding* You need a greenfield project that achieves <50 microseconds (p99) internal tick-to-trade latency on the "Hot Path". The system should leverage Aeron and SBE to eliminate garbage collection and object copying, running efficiently on AWS c5n instances with Kernel Bypass and CPU Pinning enabled. *Approach* I'll work on the following milestones: 1. *Milestone 1: The "Tuned" Foundation* - Custom UserData Boot Script for Amazon Linux 2023 to isolate CPU cores, disable C-States, and configure HugePages - Optimized Aeron Media Driver configuration file tailored for specific hardware profiles 2. *Milestone 2: The Schema & "Ping-Pong" Benchmark* - SBE XML Schema definitions for 5 core message types with explicit padding for 64-byte cache line alignment - A C++ "Ping-Pong" latency test harness proving <5 microsecond round-trip time between two local processes via IPC 3. *Milestone 3: The Core Event Loop Skeleton* - A single-threaded, lock-free C++17/20 application skeleton that pins itself to an isolated core, implements a busy-spinning duty cycle, reads from an Aeron Subscription, writes to an Aeron Publication using putOrdered (Store-Release), and ensures zero allocation inside the main loop Let's discuss further.

@adisonw

How do you do? Your project aligns very closely with my experience building ultra-low-latency trading components where determinism, cache efficiency, and predictable microsecond-level execution are mandatory. I have hands-on expertise with Aeron IPC, SBE schemas, CPU isolation, kernel bypass, and lock-free C++ event-loop architectures tuned for HFT workloads on AWS-class hardware. I can deliver the three milestones exactly as structured: a fully tuned Amazon Linux boot profile with isolated cores and HugePages; rigorously aligned SBE message schemas and a <5µs “ping-pong” benchmark; and a single-threaded, zero-allocation C++17/20 core loop with Aeron publications/subscriptions, store-release semantics, and strict CPU pinning. My focus will be achieving stable p99 performance with verifiable metrics and clean, maintainable code. I’m accustomed to disciplined profiling, flame-graph analysis, and ensuring no hidden GC, heap, or syscall noise exists in the hot path. I can begin immediately and complete Phase 1 within the requested timeline. I would be glad to discuss architecture details and confirm hardware assumptions before starting. Adison W
